Hva betyr feilkoden?
The heater control module has received too high a supply voltage for a period of time. The fault code is then set, and the heater cannot be started until the fault code has been erased. The cause may be a damaged generator, or a battery charger or starter unit connected with the wrong charge voltage.
Mulige årsaker
- Damaged generator
- Battery charger or starter unit with the wrong charge voltage is connected
Hva du kan gjøre
- 1If a battery charger or starter unit is connected to the car, disconnect it and then erase the fault code.
- 2Start the engine and measure the battery voltage with a multimeter. Too high a voltage with the engine running points to a fault in the charging.
- 3If the voltage is too high with the engine running, have a workshop check the generator.
- 4Check that the fuse for the heater is intact and that the connectors to the control module are firmly seated.
- 5Test drive the car and activate the heater to check that it starts and works as it should.
