Hva betyr feilkoden?
The CEM both sends and receives information over the LIN bus and communicates with the rain sensor. The fault shows that no communication arrives from the rain sensor at all, so the automatic windscreen wiping does not work.
Mulige årsaker
- Contact resistance, oxidation or a loose connection in connectors and joints
- Damaged rain sensor
Hva du kan gjøre
- 1Read off and note the code and check whether it returns when the ignition is switched on
- 2Check that the connector to the rain sensor is fully engaged and not corroded
- 3Check that the fuses for the windscreen wipers are intact
- 4Use a multimeter (ignition off, connector unplugged) to check that the wires to the rain sensor have no break and no contact with ground or battery positive
- 5If the fault remains, have a workshop check the rain sensor and the wiring
Symptomer du kan merke1
