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 brake control module (BCM) has found that the wheel alignment or steering alignment is incorrect. The code only applies to cars with DSTC, the stability system, and most often points to the steering angle sensor or the alignment. The stability systems may therefore be switched off.
Possible causes
- Incorrect wheel alignment
- Incorrect steering alignment
- Damaged steering angle sensor
What you can do
- 1Check whether the car has recently had a wheel alignment or work on the steering, as incorrect alignment often causes this code
- 2Read the codes in the steering angle sensor and troubleshoot them with diagnostic equipment
- 3If the steering angle sensor is in order, have a workshop check the wheel alignment
- 4The brake and stability systems are safety-critical, so have a workshop carry out any work on the module and the sensor
Symptoms you may notice4
- General warning lamp on
- Traction control does not work
- Stability function does not work
- Anti-skid function does not work
What the fault can affect1

General guidance for car owners. Diagnosis on the car can point to a different cause.
