Was bedeutet der Fehlercode?

The fault is permanent and present right now. The steering wheel module (SWM) has registered that several buttons were pressed at the same time, so cruise control and the steering wheel buttons stop working while the fault is active. A workshop needs to find which control unit or wire is responsible.

Mögliche Ursachen

Several buttons were activated at the same time

Was Sie tun können

1Check that the buttons on the steering wheel and on the cruise control do not stick in the pressed position
2If you have a diagnostic tool: compare the button status in live data with the state when no button is pressed
3Since the fault is present, have a workshop check the switch units and the wiring between them

Symptome, die Sie bemerken können2

Cruise control does not work at all
