Was bedeutet der Fehlercode?

The CEM cannot communicate with the rear mass movement sensor (MMS) or with the movement sensor (IMS). The fault code is then set, and the alarm cannot react to movement in the rear part of the passenger compartment.

Mögliche Ursachen

Internal fault in the rear motion sensor (MMS)
Internal error in the movement sensor (IMS)

Was Sie tun können

1Check that the connector to the rear sensor is secure and free from corrosion
2Use a multimeter to check that the signal wires between the sensor and the central electronic module have no break and no contact with ground or voltage
3Check that the reduced alarm function is not activated, as the car will then not react to the sensors
4Lock the car, open a rear side window and move a hand in the back of the cabin; the alarm should sound. Silence it with the remote unlock button
5If no other fault is found, the sensor should be replaced, which a workshop should do
