Hva betyr feilkoden?
The position sensors for the left-hand gas discharge lamp are not calibrated, and the module (GDL) reports this to the central electronic module (CEM). Without calibration, automatic headlamp range control does not work. Calibration is a workshop job.
Mulige årsaker
- The position sensors are not calibrated
Hva du kan gjøre
- 1Check whether anything has recently been done to the left headlamp, such as removing or replacing the lamp, since the calibration may then have been lost
- 2Check that the position sensors are fitted correctly
- 3Have a workshop calibrate the position sensors with the car unladen and on a level surface
Symptomer du kan merke1
- Automatic headlamp range control does not work
Hva feilen kan påvirke1
- The shortest headlamp range is used
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
