What does this fault code mean?
The audio control module (AUD) checks the signal from the rear seat active noise cancellation microphone. If the signal is too low, most often because of a short to ground or the microphone wires shorting together, the code is set. It appears while the module is powered and usually gives no noticeable symptoms.
Possible causes
- Signal wire between the module and the microphone shorted to ground
- Short circuit between the two microphone signal wires
