Was bedeutet der Fehlercode?

ICM keeps watch on its link with the integrated audio module (IAM). The code is set when that communication is disturbed or the IAM is missing, and the car's audio functions can then fail. Although the code is labelled audio module, it concerns communication with the IAM.

Mögliche Ursachen

Internal fault inside the integrated audio module (IAM)
No integrated audio module (IAM) fitted
Damaged fuse
Open circuit in the MOST cable

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
2With a diagnostic tool, read the fault codes in the infotainment system. If codes for a MOST break or for the audio unit are stored, work through those first
3Check that the connectors in the MOST network between the audio unit and the infotainment control module are clean and firmly seated
4If the fault remains, a workshop may need to check the integrated audio module and the MOST cable
