Was bedeutet der Fehlercode?

ICM tests whether the back button has jammed. The code is set when the button has been held active for longer than allowed, so it concerns the back button even though the code is labelled button 1.

Mögliche Ursachen

The back button has jammed in the pressed position

Was Sie tun können

1Check that the fuses are intact. Their locations are given in the owner's manual or on the fuse box cover
2Press the back button a few times and see whether it returns. Is it staying down or sticking?
3Check that the button springs back freely without resistance, and clean away any visible dirt around it
4With a diagnostic tool, read the back button value in live data and check it switches as the button is pressed and released
5If the button stays jammed and cannot be freed, a workshop can replace the keypad

Symptome, die Sie bemerken können4

Buttons on the keypad do not work
Steering wheel audio controls do not work
The audio unit does not work
On S80, V70 and XC70 built before the end of August 2008: the display on the audio unit or the radio does not work
