Hva betyr feilkoden?
Although the code is named signal too low, it means the relay coil for the headlamp washing gets too high a signal. The headlamp washer motor then does not work, caused by a signal wire shorted to supply voltage or by a damaged relay.
Mulige årsaker
- Signal wire short-circuited to supply voltage
- Damaged relay
Hva du kan gjøre
- 1Replace the headlamp washing relay and activate the windscreen washer: if the high-pressure washing then works, the old relay was damaged
- 2Clear the code and check whether it returns with the ignition on
- 3Look for chafing on the signal wire where it may have touched voltage
- 4Use a multimeter to check that the signal wire has no contact with voltage when the ignition is off
- 5If no fault is found, have a workshop check the fuse box and the wiring
Symptomer du kan merke1
- The headlamp washer motor does not work
