Hva betyr feilkoden?

The rear electronic module (REM) communicates with either the alarm's inclination sensor module (ISM) or the siren (BBS), depending on when the car was built. If a serious interruption blocks that communication, the code is set and the alarm may give false alarms. Cars built before mid-July 2011 have the ISM, and later cars have the siren.

Mulige årsaker

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

Hva du kan gjøre

1Read and clear the code, then check whether it comes back
2With the ignition off, check that the connector at the rear electronic module (REM) is fully seated and free from oxidation
3With a multimeter, check that the signal cable to the inclination sensor or siren has no open circuit and no contact with ground or voltage
4With diagnostic equipment, check whether the inclination sensor or siren is listed among the control modules with the ignition on
5If the cable is intact, the REM, inclination sensor or siren may be faulty; replace the defective part
