Co oznacza ten kod błędu?
The position sensors for the headlamp adjustment are not calibrated. The fault code is stored when the central electronic module (CEM) checks them with the ignition on or the engine running, with the car stationary. The side and height adjustment then do not work correctly.
Możliwe przyczyny
- Position sensors are not calibrated
Co możesz zrobić
- 1Calibrating the position sensors is a workshop task that needs the workshop's equipment. Have a workshop do it
- 2After replacing the control unit or any position sensor, the calibration must be redone. Ask the workshop whether it was checked after such work
- 3Clear the fault code only once calibration is finished, then check that the headlamp adjustment works
- 4Check the direction of the light after calibration, since a misaligned headlamp can dazzle other road users
Objawy, które możesz zauważyć3
- Headlamp side adjustment does not follow the steering wheel correctly, or does not work
- Headlamp height adjustment is wrong or does not work

Na co może wpływać usterka2
