Hva betyr feilkoden?
The control module (CEM) exchanges messages with the windscreen wiper module (WMM), which runs the wipers. The code is set when the supply voltage to the WMM is too low, which can be caused by poor contact, a short to ground or a weak battery.
Mulige årsaker
- Contact resistance or oxidation in the terminals and connections
- The supply wire is shorted to ground
- Battery voltage too low
Hva du kan gjøre
- 1Read and clear the code, then run the wipers and see whether they work
- 2Check the battery condition and that its terminals are tight, since too low a voltage causes the fault
- 3Check the windscreen wiper fuse
- 4Check the connectors at the wiper control module for oxidation and loose connections
- 5Use a multimeter to check that the supply wire has no contact with ground (the bodywork) and is intact
Symptomer du kan merke1
- The windscreen wiper does not work
