Hva betyr feilkoden?
The fault is intermittent: the signal to the relay for the highest wiper speed was too high on an earlier occasion, but it is no longer present. It may come from a wire to the relay that is short-circuited to voltage, and then the wipers may run only at the lowest speed.
Mulige årsaker
- Wire to the high-speed relay is short-circuited to voltage
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 highest wiper speed is seated properly and that its contacts are clean and free of oxidation
- 3Look for an intermittent short to voltage in the wire between the CEM and the relay, especially where it may have chafed
- 4Use a multimeter to check that the wire has no break when the ignition is off
- 5If the fault returns, have a workshop replace the relay or check the wire
Symptomer du kan merke1
- The wipers only work at the lowest speed
