Do electric cars need oil changes?

Engine oil is an extremely important factor that helps your car operate more efficiently. So, do these types of oils work in electric cars? Or simply put: do electric cars need an oil change? This concern will be clarified in our article.

Do Electric Cars Need Oil Changes?

Traditional gasoline and diesel engines require oil to lubricate the many moving parts of the engine as well as the transmission. The pistons, valves, and other engine parts must slide smoothly against each other at very high speeds, so oil is added to the engine to lubricate these close interactions.

Adding oil to the engine will prevent overheating. Over time, microscopic metal particles accumulate in the oil from all the engine contacts, so it is necessary to change the oil and provide new oil for the engine to run better. If you do not change the oil, the engine will wear out quickly and reduce the car engine’s lifespan.

But on the other hand, in an electric vehicle, none of this happens. Unlike internal combustion engine vehicles, electric cars operate using batteries and electric motors. There are no engine pistons, valves, or moving parts that require lubrication, so oil changes are not necessary for electric vehicles.

Electric vehicles are an important goal for the automotive industry, paving the way for a greener future. Electric vehicles do not need to use engine oil to lubricate moving parts like internal combustion engine cars. So “Do electric vehicles need oil changes?”

Our answer is “Electric cars do not need regular oil changes.” Instead, new fuel sources are being sought to optimize the performance of electric vehicles and help reduce the problem of environmental pollution. However, if the vehicle is a gasoline/electric hybrid vehicle and it still has the same engine as a conventional vehicle, it will still need an oil change.

Only electric vehicles do not need to change engine oil. Although oil changes are not necessary, electric vehicles still need to change other fluids such as coolant, brake fluid, and transmission oil.

Which Parts Do You Need to Lubricate on Electric Cars?

The powertrain of the most popular electric vehicle has eliminated up to 20 moving parts compared to an internal combustion engine vehicle. Therefore, maintenance will be increasingly simpler, but there are still important parts of electric vehicles that need to be lubricated. Electric vehicle lubricants are manufactured based on research into the specific properties of electric motors to achieve superior performance.

Electric vehicle lubricants have higher technical requirements than internal combustion engine oils. They are made with the aim of ensuring vehicle specification performance, improving anti-wear performance, reducing friction, increasing performance, electrical and insulating compatibility, as well as cooling the electric motor and battery system.

EV Battery Cooling System

For the operation of electric vehicles, battery temperature is a big issue, so lithium-ion batteries are the part that needs to be checked and have coolant added periodically. Because electric cars, if not guaranteed for their cooling capacity, can lead to a very dangerous fire and explosion situation. This is the most important category in electric car maintenance.

Like the coolant in gasoline and diesel cars, drivers must regularly check and add battery coolant for electric cars to ensure the most stable and safest operation. Many electric cars have caught fire, perhaps because owners let the batteries overheat. So, keeping the coolant at the standard level is the best method.

Lubricating the Electric Motor

The electric motor not only helps the vehicle operate and move but also plays a role in energy regeneration. It can be simply understood that when using the brake or decelerating, the powertrain generates electrical energy and recharges it into the battery, thereby increasing the vehicle’s performance. Electric vehicle models can be equipped with one or more electric motors to form a drive system similar to cars using internal combustion engines such as FWD, RWD, AWD, etc.

Compared to gasoline engines with hundreds of components that need to be checked periodically, the electric motor has a much simpler structure. However, this is not a reason for users to be subjective in controlling and maintaining electric motors. Some tasks to pay attention to when maintaining this part include: cleaning the motor; checking and lubricating bearings and electrical conductors.

EV Transmissions

Most electric car gearboxes today are single-speed gearboxes, with a much simpler structure than manual transmissions and the automatic transmissions of cars using internal combustion engines (some electric car models don’t even have a transmission). Due to such a simple structure and lubrication with high-quality synthetic oil, the electric car’s gearbox is almost free from worrying damage and has great durability. Thus, this part does not require too much time and expense in electric car maintenance.

The category that requires the most attention when maintaining electric car gearboxes is the lubricating oil. Vehicle owners only need to check, top up, and replace the lubricating oil if necessary to ensure ideal performance and avoid damaging mechanical components.

The Brake Pads

Electric cars use regenerative braking with a mechanism of reversing the electric motor to slow down the wheels. Thus, the brake pads will not wear out as much as the brakes on gasoline and diesel cars. Even so, brake pads are still an item that requires electric vehicle owners to periodically check and add brake fluid, albeit with a lower frequency than internal combustion engine cars.

When the brake pads and discs are pressed together to stop, hydraulic fluid is present in normal cars. The function of this fluid absorbs water from the air over time. If the oil is not flushed regularly, it can corrode the braking system. This means that electric vehicles still need regular fluid changes. Brake fluid must be replaced every two years on most major electric vehicles such as Tesla vehicles or changed every 5 years for Nissan brand vehicles.

Other parts: when talking about lubrication for electric cars, attention must also be paid to some other details that do not require high frequency such as the airbag safety system, brake fluid, cabin air filter, system lights, steering components, and suspension.

Summary

Do electric cars need oil changes? Electric vehicles absolutely do not require oil drains, oil changes, or regular maintenance. However, the internal parts of the car also have little need for replacement or repair because there are very few moving parts inside.

Different from gasoline cars, which have internal combustion engine oil and many parts such as spark plugs, valves, fuel tanks, mufflers, drive belts, hoses, catalytic converters, etc., electric cars only use a simple single-speed transmission. Therefore, when comparing the cost of use and oil changes, it can be seen that using electric cars is more economical. If you are considering purchasing an electric vehicle, the information in this article may be useful to you.

Do Hybrid Cars Have Exclusive Maintenance Needs?

No, hybrid cars do not have exclusive maintenance needs. You will need to change the oil, replace filters, and perform other routine maintenance tasks on your hybrid vehicle just as you would on a regular car. Battery life was a concern in older hybrids, but current models do not have this issue.

Are There Tax Benefits to Buying a Hybrid Car?

One of the advantages of owning a hybrid car is that you might be able to claim a tax deduction for the purchase and maintenance costs of your vehicle. You can get a federal tax credit for certain plug-in hybrid models. To learn more about this, speak with a financial advisor.

Has There Been a Recall on the Model You Want to Buy?

It’s important to research the car model you’re interested in. And one of the best ways to do this is to check for recalls on that model. Fortunately, most hybrid cars have not been recalled, but you should still check this.

Is It Possible to Maintain the Car Yourself?

You can perform minor tasks like inflating tires or checking fluid levels in your garage. However, the electrical part of hybrid vehicles has complicated technology. Only a qualified mechanic can solve issues with such an engine.
Moreover, entrust your car to a qualified mechanic for routine maintenance tasks. This will ensure a longer lifespan for the car’s components.

Do Hybrid Cars Offer Exclusive Benefits Over Gasoline Vehicles?

Like gasoline vehicles, they have their own advantages and disadvantages. These positives can influence your purchasing decision:

  • Better for the environment as they emit less pollution.
  • Save money on gas in the long run.
  • More reliable than gasoline cars.

A hybrid is a good choice if you’re looking for a car that’s friendly to both the environment and your wallet.

Conclusion

Buying a car is a big financial commitment. And you should be more cautious before investing in new technology. By asking these questions about hybrid car maintenance, you can be sure they will run smoothly for years.

How to Disable Traction Control on Your Car

Anti-skid helps provide a safe driving experience throughout the driving process. That’s why some drivers have decided to activate the traction control system while driving. However, in certain conditions like being stuck in snow or mud, leaving traction control activated can be a disadvantage as it may cut power to your drive wheel. In this situation, you should deactivate this system, but the question is how to disable anti-skid. Let’s follow along:

It’s a very simple process, and we will describe the step-by-step instructions to disable traction control.

What is anti-skid used for? The main function of this system is to ensure vehicle grip. (Photo: pinterest.com)

What does traction control do on your car?

A traction control system or TCS is an active safety feature installed on vehicles to help your car remain stable during acceleration as well as when driving on slippery roads. The main function of this system is to ensure vehicle grip.

There is also a function to ensure traction, but the application of TCS is completely different from ABS. If the anti-lock braking system (ABS) has an effect during emergency braking, the TCS function is responsible for controlling traction when your car is moving.

Anti-skid features automatic operation based on early detection of wheel slip. As a result, vehicle safety will be ensured during travel in all weather and terrain conditions. This function is very effective when the vehicle accelerates suddenly or drives on slippery roads.

The TCS has a fairly simple structure, including a speed sensor shared with the anti-lock braking system and a cable connected to the automatic traction control valve (ATC), linked to the ECU.

Therefore, the cost of installing this system is not too expensive. The anti-skid function is controlled by a push button on the vehicle with the TC/TCL/ESC symbol. In some cases, the driver can deactivate this function.

Traction control systems in cars are usually started automatically when the vehicle is moving. However, the manufacturer still provides a control button to turn the anti-skid system on/off on the dashboard, steering wheel, or gear lever.

Because the anti-skid system does not always work. In some cases, the TCS interferes with the vehicle’s operational capability. At that point, the driver can actively disable the TCS and turn it back on later.

If you are driving on everyday roads, in icy or snowy conditions, it’s better to drive with the anti-skid system on, as it will prevent you from losing control and your tires from skidding. However, this is not always correct when applying this function; let’s move to the next part to learn more:

When should you disable traction control?

The most common case for disabling the anti-skid function is when your vehicle is stuck on muddy or icy roads. (Photo: pinterest.com)

The traction control system is such a great safety feature, so why on earth would you want to disable traction control? The most common case for disabling the anti-skid function on cars is when your vehicle is stuck on muddy or icy roads, or when the vehicle gets bogged down…

At that moment, the wheels are usually not synchronized with each other, and there will be more drive wheels spinning, which is the kind of thing we will need to spend a lot of time moving your car forward and backward. When you turn off the traction control button, it will allow you to perform this maneuver to get out of that messy situation.

If the TCS is activated, the system will be able to detect and slow down the wheel. This makes it difficult for the car to get out of the mud. A misunderstanding is that traction control increases traction. Our answer is “No” because it simply allows your vehicle to go straight.

When the car’s tires start to spin and move forward, the anti-skid system slows down the wheel rotation to reduce wheel speed. Now, disabling this function will help you easily pass the obstacle. Thus, this function will be turned off when you are stuck in ice or mud.

In what other case would drivers disable anti-skid? Another rare case for disabling anti-skid is when you want to drift. Drifting is a driving technique that intentionally oversteers the vehicle to make the wheels skid.

So, if you want to drift, you need to disable the TCS. When anti-skid is disabled, you have full control over your car’s power. It would be a disadvantage for the car’s performance if you limited your car’s speed when you are on the track and the TSC is activated.

There are two most common situations where we recommend disabling the traction control system because there is no point in activating this system. If you keep the TCS on under these circumstances, it can sometimes consume a lot of fuel and cause your tires to wear out.

How to disable traction control on your car?

It is very simple to disable the anti-skid system. In our article, we will show you 2 methods to disable this system with and without using the button:

When anti-skid is disabled, you have full control over your car’s power. (Photo: pinterest.com)

Method 1: Using a button

Step 1: Locate the traction control button

Basically, the first thing you need to do is locate the button that turns off traction control. So you should look around the dashboard area, and the button will most likely be accessible by either your right hand or your left hand.

Normally, it is probably located to the right or left of your steering wheel. After that, you should look for a button that has either a picture of the traction control logo or an acronym for the traction control system (VSA, TCS, TC, or TCL depending on the car’s model and brand).

Step 2: Turn off the TCL button

When you have located the button, you are going to press and hold it down for several moments. And by pressing this button, you will hear a “beep” sound, and you will probably see a symbol on your dashboard.

At that point, the multi-information display on your dashboard will notice that the traction control system is disabled. When you look at the dashboard, you will notice that the traction control light comes on, and this lets you know that you have disabled traction control. Now, you have achieved your goal.

Step 3: Turn off the Vehicle Stability Control (VSC)

There is a second part of this process that you need to do, which is to turn off the VSC for the entire system. You will hold the button with the VAC symbol for 3 seconds until you see the notification on your dashboard. At that point, you will get a complete shutdown of the safety system, and you can now perform your maneuver to get through the blockage on the road.

Method 2: Without using a button

Some cars do not have a traction control button, which is why we will show you how to disable the TCS without a button.

Step 1: Turn your ignition: You will insert your key into the ignition and turn it on.

Step 2: Turn on the hazard lights: This is a very important step to let other vehicles know that your car is not moving to minimize accidents.

Step 3: Press the pedal 5 times: This step will be quite easy; you just need to press the accelerator pedal 5 times while keeping your vehicle in park and not allowing it to exceed this number; this is important to remember.

Step 4: Check if traction control is disabled: After completing the above steps, if you hear the sound and notice the notification on your dashboard, it means your task is successful.

Step 5: Turn off the hazard lights

FAQ

Why is my anti-skid light on?

In some cases, the TCS light indicates that your vehicle’s anti-skid system is active and working properly. Traction control is necessary to maintain grip in slippery conditions.

Some TCS lights come on in rainy or snowy weather and then go away. When this happens, it means the system is activated due to low-traction road conditions (black ice, snow, or rain) and is helping the vehicle maintain traction.

However, if the traction control light stays on during driving in fair weather or if the light flashes intermittently, it means there are problems in your car’s system that need to be checked. This may indicate that the system is hard-coded or malfunctioning.

This problem can be caused by a faulty speed sensor that alerts the vehicle’s computer of a possible loss of grip. Alternatively, there could be a problem with the traction computer system. A flashing TCL can also mean the system is not fully functional, so it is important to be vigilant when viewing in bad weather.

Simply put, a TCL light on can indicate the system is working properly in certain situations. Anti-skid is designed to detect when the tires are not in contact with the road in icy or muddy conditions. But when you notice this light flashing or coming on in sunny weather, then you need to take precautions.

Should anti-skid be on or off?

We will tell you the truth about whether it is better to drive with anti-skid on or off. We will go over a simple answer: “It is safe to drive with traction control disabled in normal weather conditions, but it is important that you activate the system if you are likely to hit a slippery road or in bad weather conditions.”

As we know, TCS is a standard safety feature in many vehicles nowadays. It will be activated when you start your engine. The system will intervene when it detects a difference between the vehicle’s speed and the wheel rotation. It can be said that this system will be beneficial for any type of vehicle regardless of the car’s drivetrain.

But in several situations, activating traction control will be more harmful than good for your car, such as when you are stuck stationary in sand, mud, or snow. This will lead to greater engine power consumption and prevent your car from moving forward.

How to reset the anti-skid light?

Sometimes you will notice the traction control light comes on even in fair weather, and you want to reset this light first instead of visiting the mechanic. Is there a way to reset the traction control light? There are several ways to reset the TCL.

Corresponding to each different vehicle type, you will have a few ways to do this process. But we will share the most common way: First, you need to disconnect the positive cable from your battery. After that, you will press the accelerator pedal 3 times in a row. So why do we need to do this? This step will discharge the electrical system and restart your car’s computer.

Then, you will reconnect the cable and start the engine, letting it run for a few minutes. Now, the process is finished. If the traction control light continues to be faulty, you need to entrust your car to a trusted mechanic.

Main Popular Causes of Car Engine Vibrations

Engine vibrations in a car can be the result of a number of problems. Although it is assumed that the vibrations come from the engine, the axles could actually be the real cause. If you are driving a used car, the problem probably occurs more frequently and now is the time to learn more about its common causes and find solutions. Here we discuss in detail the causes of engine vibrations. Read them carefully to see if you are experiencing any of the symptoms that cause the car’s engine vibrations.

Popular Causes of Car Engine Vibrations

1 # Cause of Engine Vibrations: Crankshaft Damper

Certain engine problems can cause vibrations in your car.

If you feel that the engine is shaking, the crankshaft damper can be a factor to consider when diagnosing the causes of engine vibrations. This is because the main function of this component is to reduce vibrations. In diesel engines, its use is more extensive. If there is a chance that it is faulty or has stopped working for good, your engine will shake even more. You should contact a mechanic whenever you encounter this problem.

2# Cause of Engine Vibrations: Faulty Engine Mount

A faulty engine mount is another cause of engine vibration

This is another cause of engine vibration. This component keeps the engine attached to the chassis. In addition, it also reduces vibrations from a running engine. This part doesn’t just get damaged. Reckless driving can be the cause. Similarly, you should see a mechanic to repair your car.

3 # Cause of Engine Vibrations: Spark Plug Issues

The spark plug may be damaged and needs to be removed

If there is a problem with your vehicle’s spark plugs, the engine will vibrate more than usual. Spark plug removal can be done at home if you have all the necessary tools and knowledge to accomplish the task.

4 # Cause of Engine Vibrations: Extreme Weather Conditions

Car shaking in cold weather is very common

In freezing weather, the engine vibrates more than normal. No further action should be taken if this problem resolves itself when the car is driven in normal weather. In cold weather, the engine cannot operate at its optimal level, so vibrations increase.

5 # Cause of Engine Vibrations: Car Axle

The car axle should be the reason where the vibration comes from.

Often it seems that the engine shaking problem is rooted in the engine itself, when in reality, it’s the axles that need to be addressed. When your car is in a collision, the axles can be damaged, even if there is no apparent sign of damage. So, you should call a mechanic if you feel an increase in vibrations, just after a collision.

6 # Cause of Engine Vibrations: Wheel Problems

One of the most serious causes of engine vibrations is related to the wheel. A misaligned wheel or worn wheel bearings could be the problems if you feel the vibrations are coming directly from the steering wheel. Another cause could be deformed ball joints that cause annoying vibrations at driving speeds.

7 # Cause of Engine Vibrations: Tire Problems

This is the most common of all reasons because nearly 80% of car vibrations are related to tires. These vibrations can be corrected by tire balancing, tire rotation, or tire replacement.

8 # Cause of Engine Vibrations: Braking Problems

If the vibration appears when you press the brake, your car may have a problem with broken or worn brake discs. Significant wear can warp the brake discs, which prevents the brake pads and calipers from gripping them during braking.

These are some of the common engine vibration problems that could affect your driving experience, it’s better to look into one of these causes of car engine vibration and find out what the exact reason is. Another great suggestion for you to avoid this problem is to choose a great car with energy efficiency, reliability, and affordable price from our list of quality used cars.

How to Fix Car Engine Vibrations

To solve this problem more easily, watch the video to see how they fix engine vibrations

Low transmission fluid, tire problems, or a brake error can all cause the car’s engine shaking. But here we will talk about the cylinder, which is usually the main reason causing vibrations in your engine. Here are the steps to follow:

Step 1: Locate the Source of the Problem

Here are the key tips for all car owners

In order to solve any problem, you need to find its source, and the same goes for cylinder misfires. The easiest way for drivers is to check the diagnostic codes. The check can help you determine if your cylinders have one, several, or no misfires. The OBD-II scanner is a useful tool for this task that can be sold in all auto parts stores. As simple as it may seem, this first step will save you a lot of time and effort, rather than looking for a solution without a way out.

It’s best if you find that your cylinders have no problems. However, if they really have misfires, the reasons usually come from one of the four systems: control sensors, fuel supply, air supply, or computer. Drivers can check the amount of air, fuel, or ignition failure.

Step 2: Analyze the Problem

It is very important to analyze the type of problem you are experiencing

Understanding the problem from the start can be very helpful in this step, as different problems have different ways of solving: if you have single-cylinder misfires, this is often caused by engine failure. However, multiple random cylinder misfires can usually be caused by external sources rather than the engine itself. Finally, mechanical failure and an unbalanced rotating assembly cause no misfire codes.

Single Cylinder Misfire

The culprits of this problem are usually fuel injector problems or ignition failures. The advice for drivers here is to check the spark plugs, ignition coil, and spark plug wires. If the cylinder coil is broken, it is quite easy to determine and repair. However, many engines use one coil to power two cylinders, so if that single coil has a problem, both cylinders also die.

Also, if you get a lean status notification diagnostic code, you most likely have a faulty fuel injector.

Multiple Random Misfires

Many drivers don’t know this, but problems that affect the engine entirely like this are usually caused by “engine support” systems such as: air intake, fuel supply, or electronic systems. A dirty air flow sensor, sensor failure, and vacuum air leak can be potential culprits. Of course, air restrictions in the intake can also cause vibrations for your automobile.

Mechanical Failures

Problems with the camshaft, damaged head gasket, broken piston ring,… are mechanical problems, and they often make your car shake due to cylinder misfires. If you get no misfires, there is a high chance that you have an unbalanced rotating assembly, causing engine shaking. Many engines use balance shafts or a harmonic balancer to reduce the car’s engine shaking, so if you have one, check it, as it could be your source of the shaking problem.

Step 3: Replace Damaged Car Parts

The reasons for high side low pressure, low side high pressure

Your car’s air conditioning system can encounter various problems. A typical issue is when the unit doesn’t blow cold air, which can be troublesome in hot weather. Several causes can lead to this condition, including compressor problems, low refrigerant levels, issues with the heating or AC controls, and more. A symptom indicating a complication in the air conditioning is low pressure on the AC low side.

How to Take Pressure Readings

Several factors contribute to this condition. In fact, temperature is directly related to the system’s pressure. You can measure the refrigerant pressure at a given temperature. There is a temperature chart for refrigerant pressure that you can find available online.

To measure the pressure, connect a gauge set to the AC system and record the pressures on the low and high sides. Check the ambient temperature and see if the pressures match the numbers in the pressure chart.

Compare the pressure readings with the pressure chart. (Photo: autoowls)

Matching readings mean you don’t have to worry about the freon level. Readings higher than the chart indicate an overcharged system, while lower readings confirm a low refrigerant level and a possible leak. On the other hand, there might be a significant leak when the pressure is zero.

You can refer to the car air conditioning pressure chart below for more information:

Ambient Temperature (°F) Low Pressure (PSI) High Pressure (PSI)
65 25-35 135-155
70 35-40 145-160
75 35-45 150-170
80 40-50 175-210
85 45-55 225-250
90 45-55 250-270
95 50-55 275-200

High and Low Side Pressure in Your Car’s Air Conditioning System

The high side starts from the discharge side of the compressor and moves through the condenser where heat is transferred to condensation, then to the receiver-drier and ends at the expansion valve. The compressor creates high pressure by compressing the low-pressure vapor from the evaporator so that the high-pressure vapor can release heat at the condenser. This pressure change occurs again at the expansion valve where the refrigerant is slowed and the pressure changes.

While the low side starts at the expansion valve which creates low-pressure refrigerant that moves to the evaporator where it transfers heat from inside the vehicle and goes to the compressor where it turns into high pressure and the whole process repeats again.

AC Low Side High, High Side Low : Why Does It Happen?

The low-side pressure reading should be between 25 and 30 psi and the high side between 200 and 250 psi. But if you see the AC low side high, high side low, such as the low side is 100 and the high side is 150, there might be problems with one of the internal components.

The possible reason could be an excessive amount of freon going to the evaporator. It could also be a faulty thermal bulb unable to pick up temperature signals or a TXV stuck in the open position.

It could also be a problem with the orifice tube. This tube works as an expansion valve to regulate the amount of refrigerant flowing to the evaporator. When its opening becomes larger than the usual size, more refrigerant goes to the evaporator and creates pressure discrepancies. The same issue arises when the O-ring on the outside of the orifice tube wears out.

Check the valves on both sides. (Photo: hummerforums)

Before deciding to replace the compressor, other components you can check are the pressure switch, expansion valve, and compressor clutch. The switch is located near the expansion valve. Use an ohmmeter to see if it gives the correct reading. Also, check if the compressor clutch engages and spins the compressor when the AC is turned on. Similarly, the fan should also spin when you turn on the system.

When all these components seem to be working correctly and the AC low side high, high side low problem persists, you may need to change the compressor to fix the unit. However, it’s always better to consult a mechanic before deciding to replace a part.

Do You Charge the AC on the High or Low Side?

We will need to recharge the car’s air conditioning system with new refrigerant when the system isn’t cooling properly. But the question is whether you should charge the car’s AC on the low or high side? You can certainly charge your car’s AC from the high side, however, high-side refrigerant charging is sometimes dangerous and can damage your car’s system.

Watch the video to learn more:

When charging high-pressure gas, note that the engine is not running, the low-pressure valve is completely closed, and the high-pressure valve is completely open. Fill a tank with enough gas, then close the high-pressure valve. Note that it’s necessary to choose a charger suitable for the system’s capacity.

Can you charge the AC system from the low side? Yes, you can. The low-side port is important because it’s the point you connect to recharge the AC refrigerant. Its position varies in each vehicle, but in almost all cars, it will start at the compressor. It’s recommended not to charge until it’s 75 degrees or warmer for your vehicle’s AC unit to recharge.

Can You Use Transmission Fluid for the Power Steering Pump?

Flushing transmission fluid, radiator, brake, and engine fluid is part of a car’s regular maintenance program. Does power steering also need to be flushed? If so, can you use transmission fluid for the power steering pump? Is there a possibility of ruining the power steering components by doing this, or do both fluids have the same properties? If you are considering using transmission fluid in the power steering, this article will help you get the answers.

Is a Power Steering Flush Necessary?

Any automobile equipped with a hydraulic power steering system needs power steering fluid. It works with the power steering pump to make turning the steering wheel smoother.

Over time, the fluid collects metal particles and sludge. The thick grit resembles sand that enters the rack and pinion seals and eventually ruins them.

The owner’s manual does not mention flushing power steering fluid as routine maintenance. But, you should do it to keep the car in good condition. When flushing becomes mandatory rather than an optional task, many people ask the question: can I use transmission fluid for power steering fluid? Let’s find out the differences between the types of fluids before answering the question.

Power Steering Fluid vs ATF

Many people want to know if they can use transmission fluid in the power steering pump. Is power steering fluid the same as transmission fluid? A comparison between them will help you understand whether replacing one fluid with the other is safe.

Automatic transmission fluid (ATF) is a red-colored fluid that emits a distinct sweet smell, while power steering fluid (PS) is clear, amber, or pinkish and smells like burnt marshmallow.

Both are hydraulic fluids. But the biggest difference is that ATF contains detergents and friction modifiers. The detergents filter out grease and dirt that can enter the power steering system and damage the pump and hydraulic valves of the steering rack. The friction modifiers, on the other hand, help control excessive heat buildup from the valves and pump.

PS fluid also reduces friction between the different components of the system and excessive temperature buildup. Its other tasks are to provide hydraulic pressure to the system components and lubricate the steering pump and gearbox. But, can you use transmission fluid for the power steering pump? Let’s find out.

Can You Use Transmission Fluid for the Power Steering Pump?

It depends on the make and model of the vehicle. Some people see no problem with it, while others are completely against it unless it’s an absolute emergency.

The argument against the practice seems stronger because using the wrong oil in high volume can deteriorate and destroy parts of a system. Both ATF and PS fluids are hydraulic types, but they are not the same.

Transmission fluid serves for cleaning and friction. Being sticky and heat-resistant in nature, it improves friction between the clutch pack components for better grip. In contrast, PS fluid is mainly for lubrication and reducing friction between the various parts of the power steering system. ATF will work for a while, but it will affect the pump and gearbox seals in the long term. Using the approved PS fluid for your vehicle model is the right way to avoid any problems.

Is It Possible to Replace PS Fluid with Transmission Fluid in Any Vehicle?

So, can you use transmission fluid for the power steering pump? The answer is no! Then why do so many people speak in favor of it?

Well, you can use ATF in the power steering pump of vehicles manufactured in the late 70s or earlier. These older cars do not have the sophisticated and lightweight materials used in cars produced in the 90s and later. The power steering system of vintage vehicles is made of raw materials that can handle ATF since it is also a hydraulic fluid.

Modern cars have subtle engineering and delicate components. Every system needs the oil and fluid specifically designed for them. Thus, using a different fluid that does not meet the requirements of a specific system is harmful to it.

Many Ford and GM models accept fluid exchange, whereas you will simply ruin a BMW, Audi, Honda, or Mercedes-Benz by doing so. The best way to determine the answer to the question – can you use transmission fluid for the power steering pump – is to consult your car’s owner’s manual. It will clearly mention whether the car needs standard power steering fluid or can also run on ATF. Some models may require specific types of hydraulic fluid. For example, a Lexus LX470 will do fine with ATF, but a BMW requires a special synthetic fluid called Pentosin CHF 11S. If your car was manufactured in the 90s or later, check the owner’s manual before making a rash decision.

Should We Mix Transmission Fluid with PS Fluid?

ATF is essentially used to reduce friction and for cleaning, while PS fluid is mainly used to lubricate power steering parts. But can two types of fluids be mixed together? As we know, PS fluid and transmission fluid are both hydraulic fluids, so mixing them is not supposed to be a problem. However, since they both have different material compositions, it may lead to an issue if they are mixed and certain set requirements are not met.

One thing to note is that power steering fluid contains oil, whereas transmission fluid does not contain any oil element in its formula. Therefore, it is quite possible that there will be leaks if these fluids are used in a system with rubber parts, as oil can cause the rubber to expand. Based on this, power fluid may cause a problem.

Transmission Fluid Low Symptoms You Should Know

Transmission fluid is nothing less than the lifeblood of the transmission system. It preserves all the system’s components, allowing them to function correctly. And symptoms of low transmission fluid level can lead to irreparable wear of parts.

The damage will be even worse in an automatic car because the automatic transmission fluid (ATF) also acts as an antifreeze to prevent the engine from overheating.

What is transmission fluid used for?

Its main function is to lubricate the transmission system. Lubrication helps transfer power from the engine to the ground.

The torque converter also uses the fluid to transfer the engine’s rotational force to the transmission. The fluid also absorbs the heat created inside the system and distributes it through the radiator.

Driving with low transmission fluid is extremely dangerous because it could lead to transmission failure and other costly repairs. You need to know what happens if your transmission fluid is low and act immediately when symptoms appear.

Low Transmission Fluid Symptoms: 10 Alerts to Keep in Mind

Transmission fluid does not need to be changed for the entire lifespan of a vehicle. However, depending on the car you drive, you may need to flush it several times or change it every 50,000 miles.

The low fluid level can be the result of a leak through a cracked or worn component. In this case, you need to repair the damaged part and refill with fluid.

How to know if transmission fluid is low? Be wary of these low transmission fluid symptoms.

Gear Shifting Problem

The first sign when your car experiences a low transmission fluid level is a gear shifting problem. Dirt or grime in the fluid is the main reason for a slow transmission response.

Whether you drive a manual or automatic transmission, the gearbox oil must be clean and free of any dirt residue so it can flow inside the parts without any hitches.

Dirty oil will lead to an overly slow shift response. Low manual transmission fluid symptoms will make shifting extremely difficult.

Erratic Shifting

Erratic shifting causes the gear to shift too late or too early. It’s one of the signs of automatic cars with low transmission fluid. You can be sure of the problem if there is a clunking noise accompanying it.

The hydraulic pressure must be precise and operate smoothly to change gears in an automatic transmission. A lack of fluid will disrupt the rhythm of the shift timing.

Transmission Surging

The condition causes the vehicle to lurch forward before falling back during normal driving operations. Insufficient fluid force is the sole reason for these jerky movements.

surging transmission

Delayed Gear Engagement

The gear lever will produce a delayed response when you move it into “Drive” or “Reverse” mode. A low fluid level means low pressure in the transmission, resulting in a delay in shifting.

The response time is about 2 to 3 seconds, which is enough to tell you there is a problem with the transmission fluid.

Gear Slipping

Low transmission fluid symptoms also include the engaged gear slipping. It doesn’t let the gear stay in the mode you selected.

If the fluid level is correct, the culprit must be the buildup of residue that prevents the fluid from flowing freely.

The Transmission Overheats

One of the most important functions of the fluid is to maintain the transmission temperature at a normal level. When there isn’t enough fluid to lubricate the components, there will be a huge amount of friction, leading to the production of excessive heat.

You will encounter an overheated transmission in case of delayed shifting, gear slipping, power loss, or other related issues, as some signs indicate that the transmission fluid is low.

When you experience low transmission fluid level symptoms, immediately pull the car over to allow the components to cool down. When the temperature has returned to normal, try driving to a maintenance workshop.

Call a towing service if the symptoms persist. Remember that the transmission system will suffer severe damage if the temperature exceeds 240°F.

check fluid level

Noises

If your transmission is in good working order, you shouldn’t hear any noises while driving since it should shift smoothly. Unusual noises vary not only by manufacturers and models but also between transmission types.

When shifting gears, manual gearboxes frequently create a loud clunking or grinding noise, while automated transmissions moan or hum.

The noises may suggest that the fluid level is low, but you won’t be able to detect the problem on your own. To avoid laborious repairs due to the low transmission fluid sound, have the issue checked by a professional expert as soon as possible.

Burning Smells

Any bad smell emanating from your vehicle should guide you to the nearest maintenance center.

There are various reasons why your automobile may start emitting a burning smell, one of which is the presence of overheated transmission fluid. This symptom can indicate a low fluid level.

When a gearbox becomes too hot, the friction between components increases, causing significant buildup and damaging the transmission. If kept in this state, the transmission will eventually become injured and non-functional.

Slow Acceleration

If your car is slow to start or unresponsive when accelerating from a stop, it could be due to a transmission problem.

car accelerate slower

If you notice that you might be driving with low transmission fluid with these symptoms above, bring your car to the trusted local service workshop and have it inspected and serviced immediately.

The Warning Light is On

When a Check Engine light appears on your dashboard, you should always bring it to a repair shop to have it checked. This light can appear for various reasons, one of which is a problem with your transmission fluid.

How to Check Transmission Fluid?

If your car starts showing any of these low transmission fluid symptoms, you need to check the fluid level to be sure. Use a dipstick to see if the fluid level matches that mentioned in the owner’s manual.

You should also look for any change in color or smell, as bad fluid also leads to many transmission problems. Perform the dipstick test at least once a month and do a fluid change if the color turns brown or black, or if the fluid emits a burning smell.

If the oil level is lower than it should be, take the car to a garage to discover the source of the problem – either a leak or a damaged component. The dipstick will let you know if the problem comes from the fluid level or not.

Oil light on after an oil change: the 5 main reasons to pay attention

The oil light that comes on after an oil change is a cause for concern. You must understand that the light indicates oil pressure, not the oil level.

If this happens, it is bad for several reasons. Low pressure means that critical seals and friction surfaces of the engine are not sufficiently lubricated, which will lead to serious damage, such as an engine shut down due to low oil pressure.

Oil Light On After Oil Change: The Top 5 Reasons

Although after an oil change, there might still be something that turns on an oil pressure light. If this happens, you must stop the car and turn off the engine as quickly as possible. Let’s discover the reasons causing the problem:

Incorrect Oil Level

If the light comes on after an oil change, the wrong oil level could be the cause. Just like a low oil level, an oil level that is too high can cause oil pressure to be out of range.

You must first check if you used the oil with the correct viscosity grade, as indicated by the car manufacturer or your professional mechanic.

Then, unless you are sure you provided the correct oil, you should proceed to check the oil level.

If the oil level exceeds the line, please decrease it until it falls below the line. Furthermore, in case it slipped under the line, you might consider filling it to bring it to the line level.

Incorrect oil levels could trigger the light. (Photo: Error Code Guy @ Youtube)

Not Lubricating the Oil Filter

It is standard procedure to put oil in the filter before installing it. The engine oil pressure light may come on when oil pressure drops if you do not lubricate the filter. Do not make the mistake of cranking the engine during this time to pressurize the system.

What you should do is crank the starter after removing the spark plugs. When the system gains pressure, reinstall the plugs and start the engine.

Dirty Oil

Not changing the oil on time and poor maintenance can lead to sludge buildup in the engine. It will not wash away even if you simply change the fuel.

The deposit deprives sensitive engine parts of normal oil pressure. As a result, you will see the oil light come on after an oil change.

Damaged Pressure Sensor

If the light is still on after doing everything correctly, measure the pressure using a pressure gauge. If it shows that the pressure is good, the problem could be with the sensor and the circuit that activates the light.

The sensor is attached to the engine and has a probe that goes into an oil passage. Sometimes, dirt or any other particle enters the probe and triggers the sensor to turn on the light. The sensor is easy to replace and is inexpensive.

Oil Leak

An oil leak in a car might seem rare, but it is possible when an oil light flashes.

If your oil light is on even though you just filled and changed your oil, you might have an oil leak. To check it, place your car on a flat surface for a few hours and look for puddles underneath.

If there are no puddles but you suspect a leak, try filling your oil up to the maximum mark on your dipstick. Your owner’s manual can explain how to do this for your specific make and model.

When you start the automobile, make sure the oil light is off. Start driving and check if the oil light comes back on. Check your oil levels if it does. If they are low, it’s time to schedule an appointment for an oil leak repair.

Other indicators of oil leaks include a burning smell or smoke coming from the engine. These symptoms, however, may not always be present.

Bringing your car in for a full vehicle check is the best approach to rule out any engine oil issues.

car leaking oil

Faulty Oil Pump

You can also consider a malfunctioning oil pump as a cause for the oil light coming on after an oil change .

A faulty oil pump will circulate oil inefficiently to the moving parts of your engine, causing engine noises and overheating, which can lead to more serious problems. If you suspect your oil pump is faulty, you should immediately stop driving and go to any trusted local auto shop for a full check.

FAQ on Oil Light On After Oil Change

  1. How long does the oil light stay on after an oil change?

Generally, you have about 2 weeks or 500 miles of driving before a flashing oil light becomes a serious problem.

However, once it reaches that point, things can deteriorate quickly, leading to catastrophic mechanical damage. So, try to get your car repaired as soon as possible.

  1. Is it safe to drive with the oil light on?

If your oil light comes on while you are driving, you must pull over immediately and turn off the engine. When you run low on oil, your engine may stall and refuse to start. If your automobile suddenly stops while you are traveling, you could have big problems.

  1. Is it serious when the engine oil light comes on?

When the oil warning light comes on, it indicates that the engine oil pressure has dropped to a dangerous level. An engine with low oil pressure can quickly damage it.

  1. Why is my oil level light on if I don’t need oil?

If the low oil pressure stops the engine but the oil is full and conditions are normal, or even if the engine is running normally, the most likely cause is a worn oil pressure sensor.

You can safely drive in this situation, but you must have the automobile thoroughly checked and the sensor replaced by a qualified mechanic as soon as possible.

  1. Why does my oil light flash when I’m driving?

Other issues that cause the oil light to flash include oil leaks, oil contamination, a faulty oil pump, a damaged oil pressure sensor, low engine oil level in your car, damaged oil pressure sensor cables, and a clogged oil pump or filter.

  1. Why does the oil light come on while I’m idling?

If the oil light flashes when the vehicle is stopped or idling, the oil sensor may be faulty or the pressure is too low. When it’s not moving, the engine must have at least 5 PSI. If the PSI is below 5, the oil light will activate and flash.

Conclusion

The oil light coming on after an oil change is a serious problem without any prior warning. It means that there is no oil flowing inside the engine parts.

If you continue to operate the car in this condition, the entire engine could be damaged. So, when the light is on, tow it to a mechanic to discover the fundamental problem and fix it.

How to Fix Low Compression in a Cylinder?

If there is low compression in a cylinder, you will face many problems, including misfires when starting the car or poor engine performance. So, how to fix low compression in a cylinder?

Compression in the cylinders of an internal combustion (IC) engine occurs when air and fuel mix.

The process is necessary for the movement and operation of the car. If the compression level in a cylinder is not sufficient, problems can occur.

So, how to prevent this from happening? Well, before finding solutions, you need to have basic ideas about the reasons behind the problem.

The 5 Main Causes of Low Compression in a Cylinder

Understanding the causes of the problem will help you identify the source of the issues and repair it.

Learning about these problems will provide insight into how to fix low compression in a cylinder.

Cracked Cylinder Wall

This will trigger poor compression, leading to poor engine performance. To spot the complication, start the engine with the radiator cap open and pay attention if air bubbles come out.

These bubbles are gases from the combustion chamber escaping into the cooling system through the cracked wall.

Gasket Problems

Worn or misaligned gaskets can also cause poor compression. In this case, you can use a pressure tester to identify the problem.

It measures the compression level in the cylinder. If the readings are different, you need to check the gasket to locate the problematic spot.

Worn Timing Belt

This is the bridge between the camshaft and the crankshaft. The camshaft cannot operate when the belt breaks or fails.

As a result, the intake valve does not close and the exhaust valve is sealed. The chain reaction will lead to gases being trapped inside the combustion chamber and cause low compression.

Valve Problems

Learn how to fix low compression in a cylinder with the following circuit with us today!

Start the engine with a compression tester in place of the spark plug to identify any problem with the valve. Pay attention to gas leaks from the air intake manifold or the exhaust pipe.

The leaking noise from either of them will confirm that the valve attached to that respective system is faulty.

Worn Pistons or Piston Rings

When the pistons or piston rings are worn, the gases from the cylinder enter the engine crankcase through them.

One way to test the problem is to pour viscous oil into the spark plug hole so that it reaches the combustion cylinder.

bad piston ring

Flattened Camshaft

A camshaft lobe is located on each valve. The camshaft lobes can also wear out, preventing the valve from opening.

When the valve is closed, the cylinder cannot receive air or expel exhaust gases. As a result, compression issues occur.

Remove the valve cover and rotate the engine to inspect the valves. Keep an eye on the valve movement. If you encounter a problem, the camshaft must be replaced.

Broken Cylinder Head Gasket

Low compression in a cylinder can occur if your gasket is not properly positioned or is deteriorated. The gas will escape from the cylinder through the small hole or gap between the head and the cylinder. This prevents your engine from running properly.

Measure the compression level in the cylinder using a compression tester. If your readings do not agree, be sure to inspect your gasket.

How to Fix Low Compression in a Cylinder

The first step in repair is to ensure that the compression in one of the engine cylinders is low. Use a compression gauge to check the measurement.

If you don’t have one, take the car to an auto repair shop so a mechanic can perform the tests.

If you find low compression, the next step is to check the cylinder, valves, gasket, and piston, as you already know the problem could come from these areas.

If you can detect a crack, damage, or gap, be prepared for a long and costly job of repairing or replacing the engine.

Additionally, how to quickly fix low compression in a cylinder? If one of the cylinders has low compression, pour a teaspoon of oil into the spark plug hole and recheck.

When the compression increases, the rings are likely stuck or worn. The oil acts as a seal, helping to reduce the gap between the rings and the cylinder wall, which leads to loss of cylinder pressure.

FAQ on Low Compression in a Cylinder

  1. Will low compression damage the engine?

If there is no compression, it indicates that a more serious mechanical fault has occurred, preventing your engine from even starting.

When the cylinder does not produce adequate compression, the force is insufficient to drive the piston and crankshaft, leading to your automobile completely breaking down.

  1. Can you still drive a car with low compression on one cylinder?

If you have engine compression problems, your automobile may misfire when you start the engine, run poorly, or not start at all if the compression is low or non-existent in all cylinders. With low compression, you cannot drive your automobile for very long, if at all.

  1. Is it expensive to fix low compression?

There are several probable causes of poor compression, but you can expect to pay between $100 and $200 to fix it. Your expenses at the mechanic include both labor hours and any parts needed to repair your vehicle.

  1. What is a good reading from a compression test?

A good compression measurement for a gasoline engine is between 125 and 175 PSI, while the standard for a diesel engine is between 275 and 400 PSI.

  1. Can a low compression engine use high octane fuel?

When a low compression engine is fueled with higher octane gasoline, the fuel does not burn properly, resulting in less power but maximum emissions.

  1. What is the best fuel for a low compression engine?

In general, engines with compression ratios of 9.3:1 or less can safely run on 87 octane unleaded fuel.

Engines with higher compression ratios typically require higher octane fuels. Many owners of automobiles designed to run on 87 octane fuel report pinging and knocking.

Symptoms of the Transmission Control Module: Discover the Bad Ones

There are several symptoms of a bad transmission control module that warn you something is wrong and the most likely culprit is the module.

When this small device wears out or is damaged, your car struggles with degraded performance and driving becomes a chore rather than a pleasure.

What is a Transmission Control Module?

The transmission control module is the driving force behind the mechanism of an automatic transmission. It is a small but necessary component for the efficient operation of the transmission.

The transmission plays the main role in transferring this power, and the module is the component that controls the transmission. You will find this small component on the rear face of the engine.

Based on the information it receives from the engine, the module is key to shifting gears and changing speeds.

What it does is transmit the received signals to the clutch, which then executes the orders by making the necessary adjustments to fuel consumption and power output.

VLUU L200 / Samsung L200

Some computerized modules have internal memory to remember information about your driving habits and apply it to perform the correct gear adjustments.

You need to be aware of several faulty signs of the transmission control module, as a malfunction in any one of them will affect the car’s performance.

Symptoms of a Faulty Transmission Control Module You Need to Be Aware Of

After learning about the transmission control module location and its function, let’s proceed to discover what happens when a transmission control module fails?

The signs of a bad transmission control module are not hard to detect if you know and understand what they are and where they come from.

Here are some transmission control module problems that you should never ignore:

Performance Issues

Does your car experience a lag in acceleration when you press the pedal? Does it no longer accelerate like it used to? This could be one of the bad TCM symptoms warning you that the device is not working properly.

The car must shift through different gears with precise timing to accelerate, and the module is the component primarily responsible for this operation. A lag in acceleration means it has malfunctioned and needs repair.

Gear Shifting Problems

There can be several gear shifting problems, warning you of bad transmission control module symptoms. Some of the most common issues are:

  • Not downshifting properly when the car stops at a traffic light
  • Delayed response when shifting from a lower gear during acceleration
  • Shifting into neutral without warning
  • Not being able to get out of neutral mode
  • Randomly shifting from one gear to another
  • Accelerating slowly or getting stuck on an incline

These are all symptoms of a bad transmission control module, indicating a problem with the component.

However, you can easily check if the module is the source of the problem in the case of a manual override. There will be no doubt about it if you can manually shift to the correct gear.

Struggling with Energy Efficiency

One of the notable signs of a bad transmission control module is lower fuel economy. A transmission malfunction means the engine has to work harder when traversing rough terrain or climbing a mountain road.

When this happens, the car is likely to consume more fuel than usual. If the frequency of your trips to the gas station increases for no apparent reason, the problem could be with the transmission module.

Nowadays, many automobiles have an information screen showing the current fuel consumption along with other variables. This makes it easier to know if the car is consuming more fuel than necessary.

Cars Stuck in Limp Mode

A notable and aggravating indication of a malfunctioning TCM is your vehicle getting stuck in “limp mode.”

Most cars activate this self-preservation mode when the TCM identifies a major problem with the transmission, provides incorrect data, or simply stops interacting with other control modules inside the vehicle.

Limp mode, in effect, prevents the automobile from shifting into higher gears, thereby limiting your vehicle’s power and speed.

What Causes Bad Transmission Control Module Symptoms?

Here are some reasons why the transmission control module fails.

Wear and Tear

The older your car gets and the more miles you put on it, the more parts wear out and fail. Weather conditions, road conditions, corrosive foreign chemicals, and lack of maintenance all contribute to wear and strain.

car wear and tear

Generated Engine Heat

Since the transmission control module is a computer made up of electronic components, it is susceptible to heat damage.

Heat is never good for electronics, including TCMs. The metal and plastic casing of your TCM is meant to protect it from heat, but it can fail.

Vibrating Ride

Vibrations are also harmful to electronics, and automobiles vibrate a lot. The engine produces vibrations that increase with speed and RPM.

Your vehicle vibrates from road shocks. This research paper explains why vibrations are so detrimental to the TCM and its mount.

What are the Solutions?

A transmission control module is an electronic device, and a burnt circuit is the cause of its failure in most cases.

It could be a faulty resistor or transistor on a printed circuit board. Any qualified technician or experienced auto mechanic can fix the problem. You can even replace the entire module if necessary, but the device is expensive.

The good news is that sometimes the problem is not with the module itself, even if the car exhibits these similar symptoms. Instead, a clogged passage or a faulty valve solenoid in the transmission could be the cause.

The module cannot function properly because it does not receive the correct supply voltage due to problems with these parts. In this case, you can simply replace that problematic device and solve the issue at a lower cost.

Can You Drive with a Faulty Transmission Control Module?

Not at all! A problem with the transmission, especially during gear shifting, means the car might randomly shift to another gear or not shift into the correct gear while you are driving.

Both situations can be dangerous whether you are driving in the city or on the highway.

It is never safe to drive with a transmission problem. (Photo: Pixabay)

Furthermore, driving with a faulty TCM in cars will not solve the problem. On the contrary, it will worsen the condition, and your transmission could end up breaking into pieces.

Transmission Control Module FAQ

1. Can a Bad TCM Cause Transmission Slipping?

Yes, a faulty TCM can lead to transmission slipping. When the TCM fails to regulate gear changes properly, gears may not engage or disengage as they should, resulting in slipping, poor acceleration, and reduced power.

2. How Do I Know If My TCM is Causing Shifting Problems?

If you experience harsh or delayed gear shifts, even under normal driving conditions, your TCM could be the cause. Unusual noises, such as clunking or whining, during gear shifts can also be indicative of TCM issues.

3. Will a Bad TCM Trigger the Check Engine Light?

Yes, a failing TCM can trigger the Check Engine light to illuminate on your vehicle’s dashboard. Modern vehicles are equipped with onboard diagnostics that detect issues related to the TCM and generate error codes.

4. Can a Bad TCM Cause Transmission Overheating?

A faulty TCM can contribute to transmission overheating. Incorrect gear shifts and gear slipping caused by a bad TCM can generate excess heat in the transmission, potentially leading to overheating.

5. Can a Bad Battery Cause TCM Problems?

A weak or faulty battery can impact TCM performance. Voltage fluctuations can disrupt communication between the TCM and other control modules, leading to erratic behavior. It is good practice to ensure your vehicle’s battery is in good condition.
