What does this fault code mean?
The brake control module (BCM) has received faulty data from the adaptive cruise control module, which requests braking through the front monitoring system. The checksum is wrong, so adaptive cruise control does not work. The fault lies in the monitoring module and not in the brake module.
Possible causes
- Fault in the front monitoring module (FSM)
What you can do
- 1Read codes in the front monitoring module and troubleshoot them first
- 2Do not replace the brake control module for this code, as the fault lies in the monitoring module
- 3Check whether the code returns after the engine has run for a while
- 4The brake system is safety-critical, so have a workshop carry out any work on the monitoring system and the brake control module
Symptoms you may notice1
- Adaptive cruise control does not work
