What does this fault code mean?
The brake control module (BCM) has received faulty data from the airbag system's control module on the sensor CAN network, and communication with the airbag system is disturbed. The code points to a fault in the airbag system. There is no separate troubleshooting procedure for this code, so the root fault must be found there.
Possible causes
- Fault in the airbag system, which is the sending module
What you can do
- 1Read codes in the airbag system's main unit and troubleshoot them first, as this code follows the fault there
- 2This code can only be cleared once the root fault has been corrected and its own code has been cleared
- 3Check that the stability and cruise control functions work after the repair
- 4The airbag and brake systems are safety-critical, so do not work on them yourself and have a workshop carry out all work
Symptoms you may notice5
- Traction control warning lamp lit
- Stability function does not work
- Traction control does not work
- Anti-skid function does not work
- Adaptive cruise control does not work
