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?
Although the code is named blocked, it applies when the gain differs between the four amplifiers in the steering angle sensor. The signals from the two magnetic sensors are amplified in these amplifiers before reaching the processors. The fault is an internal fault in the sensor.
Possible causes
- Internal fault in the steering angle sensor (SAS).
What you can do
- 1After restarting the engine, turn the wheel fully right and then fully left, and see whether the code is still stored.
- 2With a diagnostic tool, read the counters for the code. Many incorrect drive cycles point to a recurring fault.
- 3If the fault returns, have a workshop replace the steering wheel module (SWM).
- 4The angle sensor affects the anti-spin and stability functions. 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
