CIRCUIT/SYSTEM DESCRIPTION
The up-level radio (UQA) supplies 4 channels of audio to an amplifier. The amplifier supplies 6 input signal channels to 8 speakers.

CONDITIONS FOR RUNNING THE DTC
The radio is ON.

CONDITIONS FOR SETTING THE DTC
The radio sets a current status for this DTC when a short to ground, short to voltage or an open is detected on any of the 6 speaker channel outputs from the radio.

ACTION TAKEN WHEN THE DTC SETS
No sound is present from one or more of the speakers.

CONDITIONS FOR CLEARING THE DTC
The fault condition is not present for 0.25 seconds.

DIAGNOSTIC AIDS
Speakers located in the front A-pillar are connected to the same channel as the speaker in the door. A DTC will only set after the amplifier only on up-level radios.

All speakers should function properly and make sure the DTC does not reset.

CIRCUIT/SYSTEM TESTING
1. Test the suspect speaker channel (after the amplifier) for a short to ground, short to voltage or an open.
- If a short to ground or voltage can not be found, replace the amplifier.
