Was bedeutet der Fehlercode?
At an earlier point the engine control module (ECM) detected an internal fault in itself, but the check shows the fault no longer exists. It is therefore intermittent and may already be gone when you read the code. The code is set in the engine control module.
Mögliche Ursachen
- Signal fault inside the engine control module
- Defective engine control module
Was Sie tun können
- 1Read off the fault code and note it, then erase it and test-drive to see whether it comes back
- 2Check the fuses for engine management and that the battery is charging as it should
- 3If the fault comes back or the engine will not start, have a workshop check the engine control module, since the fault is in it
Symptome, die Sie bemerken können1
