Was bedeutet der Fehlercode?
The upper electronic module (UEM) regularly tests the communication with the rain sensor. The code is set when the signal wire to the sensor is shorted to voltage. It is not set while UEM-0081 is already stored. A faulty rain sensor may also be the cause.
Mögliche Ursachen
- The rain sensor's signal wire is shorted to voltage
- Faulty rain sensor
Was Sie tun können
- 1Put the wiper stalk in position 0 and check the function in that position.
- 2With a multimeter you can check that the signal wire to the rain sensor has no contact with battery voltage.
- 3Look for pinched or chafed spots on the two wires to the rain sensor.
- 4Check that the connectors at the rain sensor and the control module are not corroded.
- 5If no other fault is found, have a workshop replace the rain sensor.
