Hva betyr feilkoden?
The central electronic module (CEM) has registered that the signal from the right xenon lamp is too high or missing altogether. The actuator motor is powered through the parking lamp circuit, so a fault in that circuit can leave the motor without voltage and make the fault appear.
Mulige årsaker
- Signal wire short-circuited to voltage
- Open circuit in the signal wire
- The motor that moves the xenon lamp has seized
- Faulty or broken motor that moves the xenon lamp
Hva du kan gjøre
- 1Check that the right parking lamp works, because the actuator motor is powered through the parking lamp circuit
- 2Check the main fuse, the passenger compartment fuse and the parking lamp relay
- 3With the ignition on, switch between low and high beam to see whether the fault is permanent or has occurred before
- 4With a multimeter, check that the signal wire to the right lamp is continuous and has no contact with voltage when the ignition is off
- 5If no fault is found, have a workshop replace the right headlamp
Symptomer du kan merke4
- The low beam is constantly lit
- The high beam is constantly lit
- Road surface lighting does not work
- Headlamp aim is wrong or the height adjustment does not work
Hva feilen kan påvirke1
- The shortest beam range is used
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
