Hva betyr feilkoden?
The engine control module (ECM) has registered an internal fault in its internal reference voltage, the voltage the module uses internally. The fault is intermittent: it occurred on an earlier occasion, but it is no longer present when checked. The code is set in the engine control module.
Mulige årsaker
- Signal fault in the module's internal reference voltage
- Defective engine control module
Hva du kan gjøre
- 1Note the fault code, erase it and test-drive the car to see whether the fault comes back
- 2Check that the fuses for engine management are intact and that the battery terminals are tight
- 3If the fault returns or the engine will not start, have a workshop check the engine control module, since the fault is inside it
Symptomer du kan merke1
- The engine does not start
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
