What does this fault code mean?
The steering wheel module (SWM) continuously checks whether its configuration matches the car's equipment. The fault concerns an invalid combination of the steering wheel switches and the software in the car, so the steering wheel switch functions are missing.
Possible causes
- Invalid combination of the steering wheel switches and the software in the car
What you can do
- 1If the steering wheel switches have been replaced recently, check that they are intended for this car
- 2If you have a diagnostic tool: read the steering wheel switch status in live data and see whether any switch responds when pressed
- 3Have a workshop check that the correct switch sets are fitted, since the software must match them
Symptoms you may notice1
- No function for the steering wheel switches
General guidance for car owners. Diagnosis on the car can point to a different cause.
