Hva betyr feilkoden?
The fault code is set when the heater control module measures too high a voltage across the glow plug. This points to the cable being short-circuited to battery positive or to an open circuit. The heater's function is then blocked, and the heating in the cabin can be poor.
Mulige årsaker
- Contact resistance and oxidation in the connections
- Open circuit in the wiring
- Cables short-circuited to ground
- Damaged glow plug
Hva du kan gjøre
- 1With the ignition off, look for signs of corrosion, green or white deposits, in the connectors at the glow plug and on the heater.
- 2Look for visible damage to the wiring, such as chafing or breaks, from the heater to the glow plug.
- 3Use a multimeter to check that the cable to the glow plug has no contact with ground (the body) and is not broken.
- 4Replace the glow plug if its connector or cable is damaged.
- 5If the connector on the heater is damaged, have a workshop assess whether the fan motor needs replacing.
- 6If the fault returns after checking the wiring, have a workshop check the software in the heater control module.
