Hva betyr feilkoden?
Although the code is named faulty signal, it means the CEM has an internal fault. The rear wiper motor then does not work, and because the same relay also controls the windscreen wipers and the front washer, they can be affected too.
Mulige årsaker
- Fault inside the control module
Hva du kan gjøre
- 1Clear the code and check whether it returns with the ignition on
- 2Check that the windscreen wipers and the front washing work, since the same relay controls them
- 3Check whether the rear wiper runs; if it runs now, the fault occurred earlier and is intermittent
- 4If you have a diagnostic tool, read the customer parameters and see whether anything is out of line
- 5If the fault returns, have a workshop replace the central electronic module (CEM)
Symptomer du kan merke3
- The rear wiper motor does not work
- Front windscreen washing does not work
- The windscreen wipers do not work
