Co oznacza ten kod błędu?
The right main headlamp control unit (RHCU) receives too low a voltage, according to the fault code. It drives the headlamp motors, so side and height adjustment and automatic high beam can be affected. The cause may be a fault in the supply or a damaged control unit.
Możliwe przyczyny
- Incorrect voltage supply to the right main headlamp control unit (RHCU)
- Supply wire shorted to earth or voltage
- Damaged right main headlamp control unit (RHCU)
Co możesz zrobić
- 1Check that the fuses for the headlamps are intact
- 2With the ignition on, use a multimeter to check the supply to the right headlamp. Too low a voltage, or none, points to a supply fault
- 3With the ignition off, check whether the supply wire has contact with earth or voltage, since that can give too low a voltage at the control unit
- 4Remedy the fault and clear the fault code. If it returns, have a workshop check the right headlamp control unit
Objawy, które możesz zauważyć4
- Side adjustment of the right headlamp does not follow the steering wheel correctly, or does not work
- Height adjustment of the right headlamp is wrong or does not work
- A message appears in the information display
