Was bedeutet der Fehlercode?

The code is set when the rear electronic module (REM) registers a serious interference in its communication with the alarm's inclination sensor module (ISM) or siren (BBS), for example that communication is blocked. The alarm may give false alarms. Which of the two applies depends on when the car was built.

Mögliche Ursachen

Short-circuit between the signal cables
Open circuit in one of the signal cables
Internal fault in another control module on the same part of the network

Was Sie tun können

1Read and clear the code, road test the car and check whether it comes back
2With a multimeter, check that the signal cable to the inclination sensor or siren has no open circuit, no short to voltage and no contact with ground
3With the ignition off, check that the connector at the REM is fully seated and free from oxidation
4With diagnostic equipment, read the control modules on the network; if the inclination sensor or siren is missing there, the communication is probably broken
5If the cable is intact, replace the defective component or have a workshop determine which one it is
