Hva betyr feilkoden?
The fault is intermittent: the CEM registered that the relay for the front windscreen washer motor was short-circuited to voltage on an earlier occasion, but it is no longer present. The front washing may then fail.
Mulige årsaker
- Short to voltage on the signal line
Hva du kan gjøre
- 1Clear the code and check whether it returns; an intermittent fault can be a temporary disturbance
- 2Check that the relay for the front washer motor sits properly and that its contacts are clean and free of oxidation
- 3Check the connector for play and for signs that the wire briefly touches voltage
- 4Look for chafing on the wire between the relay and the CEM where it may have touched voltage
- 5If the fault returns, have a workshop check the relay and the wiring
Symptomer du kan merke1
- Front windscreen washing does not work
