Possible Causes

NOTE: The listed causes may not be a complete list of all potential issues and there may be other causes.

• Faulty Cooling Fan 3
• Cooling Fan 3 harness is open or shorted
• Poor electrical connection in the Cooling Fan 3 circuit

Description

The control modules connected to the serial data circuits monitor communication during normal vehicle operation. Operating information and commands are exchanged between the control modules. Each module in the serial data circuit maintains a transmit error counter and a receive error counter. The counter values increase with detected errors and decrease with error-free messages. The Diagnostic Trouble Code (DTC) is set when the Cooling Fan 3 status signal message counter is incorrect.

How to Repair

Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

• Illuminated MIL (or Service Engine Soon Warning Light illuminated)

Possible Causes

NOTE: The listed causes may not be a complete list of all potential issues and there may be other causes.

• Faulty cylinder 2 ignition coil
• Cylinder 2 ignition coil harness is open or shorted
• Poor electrical connection in cylinder 2 ignition coil circuit
• Faulty Engine Control Module (ECM)

Description

The Engine Control Module (ECM) must determine if a misfire is occurring and identify the specific cylinder(s) and severity of the misfire event, and whether it is relevant for emissions or damaging to the catalyst. To accomplish these tasks, the control module monitors the crankshaft for acceleration losses during the firing segments of each cylinder according to the firing order.
The calculation of engine misfires/roughness is derived from differences in period duration (T) of individual increment gear segments. Each segment period consists of an angular range of 120° of crankshaft angle starting 78° before Top Dead Center (TDC).
If the expected period duration exceeds the allowed value, a misfire fault for that particular cylinder is recorded in the ECM’s fault memory. Depending on the measured misfire rate level, the control unit illuminates the “Service Engine Soon” light, may cut fuel to the particular cylinder, and may switch lambda operation to open loop. All misfire faults are weighted to determine whether the misfire is relevant for emissions or damaging to the catalyst.

How to Repair

Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector pins.

Possible Symptoms

• Faulty spark plug
• Faulty ignition coil
• Intake vacuum leak
• Faulty camshaft position sensor
• Ignition coil harness is open or shorted
• Poor electrical connection in ignition coil circuit

Description

Under CARB/OBD regulations, the Engine Control Module (ECM) must determine if a misfire is occurring and also identify the specific cylinder(s) and severity of the misfire event, and whether it is emissions-relevant or damaging to the catalyst. To accomplish these tasks, the control module monitors the crankshaft for acceleration losses during the firing segments of each cylinder based on the firing order.
The misfire/engine roughness calculation is derived from the differences in period duration (T) of individual increment gear segments. Each segment period consists of a 120° crankshaft angle range that begins 78° before top dead center (TDC).
If the expected period duration exceeds the allowed value, a misfire fault for that particular cylinder is recorded in the ECM’s fault memory. Depending on the measured misfire rate level, the control unit illuminates the Service Engine Soon light, may cut fuel to the particular cylinder, and may switch to open-loop lambda operation. All misfire faults are weighted to determine whether the misfire is emissions-relevant or damaging to the catalyst.
