What does this fault code mean?
The signal from the right-hand steering wheel switch (SWSR) is faulty, so the steering wheel audio and phone buttons do not work. The cause is a button stuck in the activated position or a faulty switch.
Possible causes
- One or more buttons on the right-hand switch (SWSR) stuck in the activated position
- Faulty right-hand steering wheel switch (SWSR)
What you can do
- 1Check that the fuses are intact
- 2Press the right-hand steering wheel buttons one at a time and check whether any stays in or fails to return
- 3Read and note the code, clear it and road test to see whether it returns
- 4With diagnostic equipment, read the button status in live data while pressing and releasing the buttons
- 5The steering wheel angle sensor is part of the car's safety systems, so have a workshop repair the fault if it remains
Symptoms you may notice3
