Hva betyr feilkoden?
The control module registers that the headlamp level setting signal stays outside its measuring range for a longer period. This occurs when a wrong spare light switch panel, one with a thumb wheel for manual adjustment, has been fitted, or when the signal wire to the adjustment motors is shorted to earth or supply voltage. The headlamps are set to their lowest position.
Mulige årsaker
- A thumb wheel for manual headlamp adjustment is fitted
- Short circuit to earth in the signal wire to the headlamp adjustment motors
- Short circuit to supply voltage in the signal wire to the headlamp adjustment motors
Hva du kan gjøre
- 1Check whether the light switch panel has a thumb wheel for manual headlamp level adjustment. A car with xenon lamps should not have one
- 2Have a workshop fit a light switch panel without a thumb wheel if the wrong spare part was fitted
- 3Use a multimeter to check that the signal wire to the adjustment motors is not shorted to earth or supply voltage
- 4After the repair, check that the fault code does not return
