Was bedeutet der Fehlercode?
The engine control module (ECM) controls the glow plugs through a relay in the engine bay relay and fuse box. The fault is set when the circuit to the glow plug relay is outside its normal signal range, and it is checked with the ignition on. The glow plugs help the diesel engine start when it is cold, so the fault is mainly noticed on cold starts.
Mögliche Ursachen
- Contact resistance or oxidation in the connections
- Open circuit or short to ground or voltage in the signal wire to the relay
- Open circuit or short to ground in the supply wire to the glow plug relay
- Open circuit or short to voltage in the ground wire
- Damaged glow plug relay
Was Sie tun können
- 1Check that the fuses are intact. Their locations are shown in the instruction manual or on the fuse box cover
- 2Switch off the ignition and check the connector to the glow plug relay for contact resistance and oxidation
- 3Use a multimeter to check that the signal wire to the relay has no open circuit and is not shorted to ground or voltage
- 4If you have a diagnostic tool, activate the glow plug relay and listen for it to click when it switches on
- 5If the fault remains, have a workshop with diagnostic equipment check the wiring to the glow plugs, as this needs measurement
Symptome, die Sie bemerken können5
- The engine is hard to start, especially when cold
- The engine cranks slowly
- The engine hesitates, surges or runs roughly, sometimes or all the time
- Poor performance and lack of power
- Cruise control does not engage
