System
Steering Angle Sensor (SAS)
Volvo models this fault code applies to
Applies to the following models:
9 modelsS60 (2011–), S80 (2007–), V40 (2013–), V40 Cross Country (2013–), V60 (2011–), V60 Cross Country (2015–), V70 (2008–), XC60 (2009–), XC70 (2008–)
What does this fault code mean?
The code means the steering angle signal is implausible, because the wheel has been turned too quickly. The cause is a damaged sensor, which then sends incorrect information to the other control modules.
Possible causes
- Damaged steering angle sensor.
What you can do
- 1With the ignition on, turn the wheel a short distance to the right and then to the left, and check whether the code is still stored.
- 2With a diagnostic tool, read the counters for the code. Many incorrect drive cycles compared with correct ones point to a recurring fault.
- 3If the code returns, have a workshop replace the steering wheel module (SWM).
- 4The steering angle sensor is part of the steering and stability system. Have a workshop carry out the repair rather than working on the wheel yourself.
Symptoms you may notice5
- A yellow warning symbol and text message show in the display
- The anti-spin and anti-skid warning lamp lights up or behaves abnormally
- The anti-spin function does not work
- The stability function does not work
- The active chassis does not work
What the fault can affect1
- The sensor warns the other control modules that the data it sends is wrong
General guidance for car owners. Diagnosis on the car can point to a different cause.
