Hva betyr feilkoden?
The ECM checks the signal wire to the system relay coil and sets the code when the signal is missing. The fault shows at start attempts: the engine does not start or turn over, and no click is heard from the relay.
Mulige årsaker
- Poor connections, contact resistance or oxidation at the terminals
- Break in the supply to the system relay coil
- Break in the signal wire
- Damaged system relay
Hva du kan gjøre
- 1Check the battery voltage and condition, since weak voltage can cause the fault
- 2Check that the generator is charging the battery
- 3Check the connectors at the engine control module and at the system relay for contact resistance and oxidation
- 4Use a multimeter to check the signal wire for an open circuit
- 5If no fault is found and the fault remains, a new system relay can be tried; a workshop should replace it
Symptomer du kan merke3
- The engine does not start
- The engine does not turn over at start attempts
- No click from the relay when it should engage
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
