What does this fault code mean?
The brake control module (BCM) is waiting for the steering angle sensor to be initialised, which happens when the steering wheel is turned a little. If initialisation has not taken place after a longer drive at a sufficient speed, and the brake module then calculates a wrong steering angle, the code is set. It most often applies when the driver has driven for a long time without turning the wheel.
Possible causes
- The driver has driven for a long time with an uninitialised steering angle sensor after start-up
- Fault in the steering angle sensor control module (SAS)
What you can do
- 1Think back on whether the car has been driven for a long time without the steering wheel being turned after start-up, as this may be the cause
- 2If other codes are stored in the steering angle sensor, troubleshoot them first
- 3Turn the steering wheel a little while driving so the sensor initialises, then clear the code
- 4The brake and stability systems are safety-critical, so have a workshop carry out any work on the steering angle sensor and the modules
Symptoms you may notice5
- Traction and anti-skid 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
What the fault can affect3
- Stability control is disabled
- Traction control is disabled
- Dynamic stability control (AYC) is disabled
General guidance for car owners. Diagnosis on the car can point to a different cause.
