What does this fault code mean?
The IAM unit reads the signal from the speaker in the right rear door as too low. The signal wire has contact with ground, meaning the car body, which pulls the signal down.
Possible causes
- Short circuit to ground on the signal wire between the module and the speaker in the right rear door
What you can do
- 1With the ignition off, check that the connectors at the integrated audio module are secure and free of oxide
- 2Follow the signal wire back to the speaker in the right rear door and look for chafing where it may have touched the car body
- 3Use a multimeter to check that the signal wire has no contact with ground (the car body)
- 4After the work, clear the fault code and check that it does not come back
Symptoms you may notice2
- No playback from the CD player
- No sound from the speakers
