Hva betyr feilkoden?
The fault is intermittent: the signal from the windscreen wiper switch was too high or missing on an earlier occasion, but it is no longer present. The signal then does not match the position of the wipers, which may cause them to run only at the lowest speed.
Mulige årsaker
- A short to voltage or an open circuit in the switch that signals operating or rest position
- Defective windscreen wiper lever
- Defective fuse for the wiper control
Hva du kan gjøre
- 1Clear the code and check whether it returns; an intermittent fault can be a temporary disturbance
- 2Look for an intermittent short to voltage or a break in the wire between the CEM and the steering wheel module (SWM)
- 3Check that the connectors are firmly seated and free of oxidation, especially near the steering wheel
- 4Check that the fuse for the wiper control is intact
- 5If the fault returns after these checks, have a workshop replace the wiper lever
Symptomer du kan merke1
