Was bedeutet der Fehlercode?

The infotainment control module (ICM) monitors the warm-up of the display. The code is set when the module finds the signal outside its normal range during the test, which starts once display warm-up has been switched on. The cause is an internal fault in the control module itself rather than in the display.

Mögliche Ursachen

Internal fault inside the ICM unit

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
2After a cold night, switch the ignition on and note how soon the display lights up
3If you have a diagnostic tool, read the fault code after switching the ignition on, clear it and see whether it returns
4If the code comes back after clearing, the fault is most likely inside the infotainment control module and it will need replacing. Have a workshop do that

Symptome, die Sie bemerken können2

The display lights up slowly
On S80, V70 and XC70 built before the end of August 2008: the audio unit, its display or the radio does not work
