Was bedeutet der Fehlercode?

The fault concerns the earthing of the glow control module. The module is earthed both through the control module chassis and through a separate earth point, and the engine control module (ECM) sets the code when one of the earth connections is faulty.

Mögliche Ursachen

Damaged fuse
Contact resistance or oxidation in the connector
Open circuit in the signal wire
Damaged glow plug relay

Was Sie tun können

1Check that the fuse for the glow control module is intact. The locations are in the owner's manual or on the fuse box cover.
2Check the earth points of the glow control module. It is earthed both through the chassis and through its own earth point, so both should be tight and clean.
3Go through the connector to the glow control module. It should be secure and free from oxide.
4Look for broken or chafed signal wires to the glow control module.
5Have a workshop check the glow plug relay and the supply to the glow control module, as this needs measurements.

Symptome, die Sie bemerken können1

The engine is hard to start and cranks slowly, especially on a cold start

Was der Fehler beeinflussen kann1

Glow plug operation is limited
