Hva betyr feilkoden?
The wiper motor module (WMM) and the rain sensor (RSM) cannot be reached over the LIN bus, even though the central module tries to communicate. The cause may be a break or short circuit in the wiring, or a damaged communication device. The rain sensor stops working, and the wipers may behave wrongly.
Mulige årsaker
- Short circuit between the LIN wires
- Open circuit in one of the LIN wires
- Damaged communication device in a control module
- Fault in another unit on the same LIN network
Hva du kan gjøre
- 1Check the fuses for the wipers and the rain sensor, using the owner's manual, and replace any that are blown
- 2With a multimeter, check the wire to the wiper motor module for breaks and contact with ground
- 3Make the same check on the wire to the rain sensor
- 4If the wires are intact, have a workshop replace the wiper motor module
Symptomer du kan merke2
- The rain sensor does not respond
- The windshield wipers do not work
Hva feilen kan påvirke2
- The wipers may run too fast or too slow, or at the wrong interval, for a time
