What is a fault code?
A fault code is a message generated by the vehicle’s onboard diagnostic system. It indicates that a problem has been detected in one or more components of the vehicle. Fault codes are typically composed of five characters:
- The first character is a letter that identifies the system involved.
- The second character is a number that identifies the type of problem.
- The last three characters are numbers that identify the specific component causing the problem.
How to read a fault code?
There are several ways to read a fault code on a Dacia DF771:
- Use an OBD-II fault code reader.
- Check the engine light (MIL).
- Count the number of flashes of the injection light.
OBD-II Fault Code Reader
An OBD-II fault code reader is an inexpensive tool that can be purchased at most auto parts stores. It plugs into the vehicle’s OBD-II port, which is usually located under the dashboard. The code reader will display the fault code and a description of the problem.
Engine Light (MIL)
The engine light is an orange or red light located on the dashboard. It illuminates when a fault code is recorded. If the engine light is on, it is important to have the problem diagnosed as soon as possible.
Injection Light
The injection light is an orange light located on the dashboard. It flashes when a fault code is recorded. The number of flashes can be used to identify the fault code.
