Normal Operation
The audio control unit directs the audio signals to the speakers through separate positive and negative circuits for each of the 4 audio channels: LH front, RH front, LH rear, and RH rear. The audio control unit provides a signal to the reverse parking aid module. When this signal is activated, the audio control unit mutes all speakers allowing the operator to hear the audible reverse indicator.
Possible Causes
- speakers
- audio control unit
- high resistance or a short to ground in the speaker circuits
