Was bedeutet der Fehlercode?

The fault concerns a short to earth on the signal wire to the starter relay. The ECM watches the voltage on this wire and sets the code when it stays below a set threshold for a set time. The fault is checked when the engine is started.

Mögliche Ursachen

Signal wire shorted to earth
Chafing, looseness or open circuit in the signal wire
Damaged starter relay
Open circuit in the feed to the starter motor
Damaged control module

Was Sie tun können

1Check that the fuses are intact. The locations are shown in the instruction manual or on the fuse list
2Use a multimeter to check that the signal wire to the relay has no contact with earth (the body)
3Check that the wire has not rubbed against the body or an edge where it passes, and that the connectors are firmly seated
4Check that the starter relay is intact and firmly fitted in its mounting
5Read off the fault code, erase it and start the engine to see whether it returns
6If the fault remains after these checks, have a workshop investigate the engine control module

Symptome, die Sie bemerken können1

The engine does not start, and this may happen always or only sometimes
