What does this fault code mean?
Two or more switches on the RTI multi-button in the steering wheel are activated at the same time, which sets the code and stops the navigation controls working.
Possible causes
- Two or more switches on the RTI multi-button are active together
What you can do
- 1Check that the fuses are intact
- 2Press one button at a time on the steering wheel multi-button and check whether any stays pressed or two work together
- 3Read and note the code, clear it and road test to see whether it returns
- 4With diagnostic equipment, follow the button status in live data while pressing the buttons one at a time
- 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 notice1
- Navigation controls on the steering wheel do not work
General guidance for car owners. Diagnosis on the car can point to a different cause.
