Hva betyr feilkoden?
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.
Mulige årsaker
- Damaged fuse
- Contact resistance or oxidation in the connector
- Open circuit in the signal wire
- Damaged glow plug relay
Hva du kan gjøre
- 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.
Symptomer du kan merke1
- The engine is hard to start and cranks slowly, especially on a cold start
Hva feilen kan påvirke1
- Glow plug operation is limited
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
