Co oznacza ten kod błędu?
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.
Możliwe przyczyny
- 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
Co możesz zrobić
- 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
