Normal Operation
The audio 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 unit provides internal circuit protection for shorts to ground, shorts to voltage, or shorts between any output circuits. For vehicles equipped with a digital versatile disc (DVD) player, the audio signals for the rear speakers are sent to the DVD player, then to the rear speakers.

DTC B2965 - sets when a short to another circuit, a short to ground, or a short to voltage is detected on any of the speaker circuits. DTC B2965 will not set due to an open in the speaker circuits.
