Was bedeutet der Fehlercode?

CEM reads the signal from the up button on the steering wheel (RTI). If the button has been held on for too long, the fault code is set. The RTI and navigation buttons on the steering wheel then do not work as they should.

Mögliche Ursachen

Damaged up button

Was Sie tun können

1If you have a diagnostic tool, read the button status in live data and check that it changes when you press and release the button
2Check that the up button does not stick in the pressed position, and press it once to see that it springs back
3Clear the fault code and road test the car to see whether it returns
4If the button is damaged, a workshop should replace it
