The up-level radio (UQA) supplies 4 channels of audio to an amplifier. The amplifier supplies 6 input signal channels to 8 speakers.
The radio is ON.
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.
No sound is present from one or more of the speakers.
The fault condition is not present for 0.25 seconds.
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 the DTC does not reset.
Note: It is recommend that Component Testing is performed before Circuit Testing when diagnosing speaker channels.
⇒ | If the DTC was set by the amplifier, test the suspect speaker input circuit for an open short to ground or short to power. If all circuits test normal, replace the amplifier. |
⇒ | If all circuits test normal, replace the radio. |
Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
