* Right subwoofer speaker output (-) -terminal 8 X1
* Left front speaker output (+)- terminal 1 X2
* Left front speaker output (-)-terminal 9 X2
* Right front speaker output (+)- terminal 2 X2
* Right front speaker output (-) -terminal 10 X2
* Left rear speaker output (+) -terminal 3 X2
* Left rear speaker output (-) -terminal 11 X2
* Right rear speaker output (+)- terminal 4 X2
* Right rear speaker output (-)- terminal 12 X2
* Front center speaker output (+) -terminal 5 X2
* Front center speaker output (-)-terminal 13 X2
* Rear compartment speaker output (+) -terminal 6 X2
* Rear compartment speaker output (-) -terminal 14 X2

• If less than the specified vallue, test both signal circuits of the affected speaker for a short to ground.

9. Reconnect all harness connectors at the amplifier. Disconnect the harness connector at the appropriate speaker.
10. Radio ON, test for 5.0-7.5 V between each of the appropriate signal circuit terminals listed below and ground.

* Front A pillar speakers - terminals A and B
* Center IP speaker- terminals A and B
* Door speakers - terminals A and B
* Rear compartment speakers- terminals A and B
* Subwoofer speaker assembly- terminals A, B, C, and D

• If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the audio amplifier.
• If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the audio amplifier.

11. If all circuits test normal, replace the speaker.

1. Ignition OFF, disconnect the X2 harness connector at the Auxiliary Radio/HVAC Control.
2. Ignition ON, radio ON, test for 5.0-7.5 V between the appropriate signal circuit terminal listed below and ground.

* Left Rear Low Level Audio Signal (+) terminal 1
* Left Rear Low Level Audio Signal (-) terminal 2
* Right Rear Low Level Audio Signal (+) terminal 3
* Right Rear Low Level Audio Signal (-) terminal 4

• If less than the specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
• If greater than the specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.

3. Ignition OFF, reconnect the X2 harness connector at the Auxiliary Radio/HVAC Control. Disconnect the X3 harness connector at the audio amplifier.
