System
Brake Control Module (BCM)
Volvo models this fault code applies to
Applies to the following models:
1 modelXC90 (2003–)
What does this fault code mean?
The all-wheel drive control module (DEM) sends to the brake control module (BCM) when all-wheel drive is active. The BCM has registered that the speed difference between the front and rear wheels is too large, so the stability function may not be activated.
Possible causes
- Internal fault in the all-wheel drive control module (DEM)
What you can do
- 1Read codes in the central electronic module first and troubleshoot them
- 2Read codes in the all-wheel drive control module and troubleshoot them according to their information
- 3Do not replace the brake control module for this code, as the fault does not lie in it
- 4The brake and stability systems are safety-critical, so have a workshop carry out any work on the all-wheel drive system and the brake control module
Symptoms you may notice4
- Red warning symbol and message in the display
- Traction control does not work
- Stability function does not work
- Anti-skid function does not work
What the fault can affect2
