Co oznacza ten kod błędu?
The engine control module watches the CAN link to both the CEM and to the brake control module (BCM). The fault code is set when that communication is wrong. The cause can be faulty software, a missing power supply to the brake control module, or a discharged vehicle battery, and the engine may then not start.
Możliwe przyczyny
- Faulty software
- Missing supply voltage to the brake control module (BCM)
- Contact resistance, loose contacts or corrosion in the terminals
- Open circuit in the wiring to the CEM or the brake control module on the high speed side
- Internal fault in another control module on the same network section
- The code can also be set if the vehicle battery has become discharged
Co możesz zrobić
- 1If the software is suspected to be faulty, have a workshop reload the software in the engine control module. If the fault remains after the reload, continue the fault-tracing
- 2Check that the battery is fully charged, since a discharged battery can cause this code
- 3Check that the fuses for the brake control module are intact and that the connectors are firmly seated
- 4Read out the fault codes in the CEM and other control modules, and fix them before erasing anything
- 5The brake control module controls ABS. If the brakes or ABS feel uncertain, do not drive the car; have a workshop check it
- 6Erase the fault code once the faults are fixed, then road test the car to see whether it returns
