Hva betyr feilkoden?
The ECM checks how the system relay operates. The fault is stored when the module detects voltage from the system relay while the relay is switched off, which suggests the relay has stuck in the energised position.
Mulige årsaker
- The voltage wire is shorted to supply voltage
- The system relay is damaged
Hva du kan gjøre
- 1Check that the fuses are intact
- 2Check that the system relay is seated properly
- 3Look for chafed wiring on the voltage wire that may have touched a live supply
- 4If you have diagnostic equipment: activate the system relay and listen for a click when it is switched off and on
- 5If none of the checks show a fault, have a workshop replace the system relay, as a damaged relay is a possible cause
Symptomer du kan merke1
- The engine does not start, hard to tell when it happens
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
