Hva betyr feilkoden?
The upper electronic module (UEM) periodically tests the communication with the rain sensor. The code is set when the signal wire to the rain sensor is short-circuited to ground, and the rain sensor then does not work. A faulty rain sensor can also be the cause.
Mulige årsaker
- The rain sensor's signal wire is short-circuited to ground
- Faulty rain sensor
Hva du kan gjøre
- 1Put the wiper stalk in position 0, clear the code and check whether it returns.
- 2Use a multimeter to check that the signal wire to the rain sensor has no contact with ground (the bodywork).
- 3Check that the connectors at the rain sensor and at the control module are firmly seated and not corroded.
- 4Look for damage on the rain sensor wiring, which consists of two wires.
- 5If no other fault is found, have a workshop replace the rain sensor.
