Hva betyr feilkoden?
The upper electronic module (UEM) checks the communication with the rain sensor at regular intervals. The code is set if either the UEM or the rain sensor registers a communication fault. The rain sensor then provides no function.
Mulige årsaker
- Contact resistance or oxidation on the signal wire
- Interference in the communication
- Faulty rain sensor
Hva du kan gjøre
- 1Check the connectors at the upper electronic module and at the rain sensor for contact resistance and oxidation.
- 2Also check the wiring to the rain sensor and to any GSM antenna. Make sure there are no sources of interference nearby.
- 3Read off the code, clear it and check whether it returns.
- 4If the fault remains, have a workshop replace the rain sensor.
