Gilt für folgende Modelle:

Was bedeutet der Fehlercode?
The brake control module (BCM) has lost contact with the airbag system's main unit (SRS) on the local sensor network and has therefore shut down its communication on that network. The fault means incorrect messages are being sent or received between the BCM and the SRS. The cause is most often a short in the wiring, and the code points to starting the troubleshooting in the module that transmits.
Mögliche Ursachen
- Short circuit to battery supply
- Short circuit to ground
- Fault in the module transmitting incorrect messages
Was Sie tun können
- 1Check the wiring on the local sensor network for shorts to supply voltage and to ground
- 2Check the communication between the airbag system's main unit, the crash speed module and the passenger weight sensor where fitted
- 3If no fault is found in the wiring, have a workshop troubleshoot the crash speed module with diagnostic equipment
- 4The airbag and brake systems are safety-critical, so do not work on them yourself and have a workshop carry out all work on the wiring and the modules
