Control Module Communication

Control module communication

Checking diagnostic trouble codes (DTCs)
Check if other control modules have diagnostic trouble codes (DTCs) for Control area network (CAN) faults. If other control modules have diagnostic trouble codes (DTCs) stop fault-tracing and fault-trace according to the information for those systems.

Do other systems have diagnostic trouble codes (DTCs) for Control area network (CAN) faults?

Yes - DONE

No - checking the wiring
