Hva betyr feilkoden?
The ECM watches the system relay. It sets the code when the signal from the relay is too low, or when the relay does not release within the expected time. The fault may show at start attempts, when the engine does not start or turn over and the relay gives no click.
Mulige årsaker
- Signal wire shorted to earth
- Signal wire shorted to voltage
- Damaged system relay
Hva du kan gjøre
- 1Check the battery voltage and condition, and that the battery terminals are tight
- 2Check that the generator is charging the battery
- 3Check the connectors at the engine control module and the system relay for contact resistance and oxidation
- 4With the ignition off, check the signal wire for a short to earth
- 5If no fault is found and the fault remains, a new system relay can be tried; a workshop should fit it
Symptomer du kan merke2
- Starting problems, with the engine not starting or turning over
- No click from the relay at start attempts
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
