Hva betyr feilkoden?

CEM reads the signal from the Volume+ button on the steering wheel. If the button has been held on for too long, the fault code is set. The radio and phone buttons on the steering wheel then do not work as they should.

Mulige årsaker

The Volume+ button has stuck in the pressed position
Damaged Volume+ button

Hva du kan gjøre

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 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
