Was bedeutet der Fehlercode?

The engine control module (ECM) monitors the voltage on the signal wire to the starter relay. The code is set when the voltage lies below a set threshold for a set time, which is treated as a fault. The fault is checked when the engine is started.

Mögliche Ursachen

Signal wire shorted to earth
Break in the signal wire
Damaged starter relay
Open circuit in the supply feeding 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
2Check that the starter relay is intact and firmly fitted in its mounting
3Check that the connectors at the starter relay and in the wiring are firmly seated and free from play, oxidation and contact resistance
4Use a multimeter to check that the signal wire to the starter relay has no break and is not shorted to earth (the body)
5Check that the supply wire to the starter motor has no break. If the fault remains, have a workshop investigate the control module
