Hva betyr feilkoden?
This variant covers intermittent faults on the transistor stage to the starter relay. The fault is intermittent, so it may have occurred before without being active now. The usual cause is an output shorted to plus. The engine does not start.
Mulige årsaker
- The output signal from the transistor stage to the starter relay is shorted to plus
Hva du kan gjøre
- 1With the ignition off, check that the starter relay is firmly seated and its contacts are clean
- 2Use a multimeter to check that the signal wire to the starter relay is not shorted to plus
- 3If the fault returns, have a workshop check the CEM, since the transistor stage is inside the module
- 4After the work, clear the code and check that the engine starts
Symptomer du kan merke1
- The engine does not start
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
