What does this fault code mean?
The steering angle sensor (SAS) has two processors that work together. The code is set when it detects an internal software fault, and the fault lies in the sensor.
Possible causes
- Internal malfunction within the steering angle sensor (SAS).
What you can do
- 1With the engine running, turn the wheel fully to one side and then fully to the other, and set it straight ahead. Check whether the code remains.
- 2With a diagnostic tool, read the counters for the code. Many incorrect drive cycles point to a recurring fault, while few point to a temporary one.
- 3If the code returns, have a workshop replace the steering wheel module (SWM).
- 4The angle sensor is part of the stability system. Have a workshop diagnose and replace it rather than working on the steering wheel yourself.
Symptoms you may notice5
- The information lamp lights up
- The anti-spin warning lamp lights up
- Traction control does not work
- The stability function does not work

What the fault can affect1
- The sensor warns the other control modules that the data it sends is wrong
