What does this fault code mean?
ICM monitors the link to the audio module (AUD). Although the code is labelled amplifier, it concerns communication with the AUD. The code is set when ICM registers a fault in that communication, and then no sound comes from the loudspeakers.
Possible causes
- Internal fault inside the audio module (AUD)
- No audio module (AUD) fitted
- Damaged fuse
- Break in the MOST cable
What you can do
- 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. If codes for a MOST break or for the audio module are stored, work through those first
- 3Check that the MOST connectors to the audio module are clean and firmly seated
- 4If the fault remains, a workshop may need to check the audio module and the MOST cable
Symptoms you may notice2
- No sound from the loudspeakers
- The loudspeakers do not work
