Diagnostic Test

1. DETERMINE FAULT
Turn the ignition on.
Turn the Radio on.
With the scan tool, erase the audio DTC's.
Cycle the ignition switch from off to on and wait 10 seconds.
With the scan tool, read the audio DTC's.
Does the scan tool display ALL OUTPUTS SHORT?

Yes

- Go To2

No

- Refer to the wiring diagrams located to help isolate a possible intermittent short.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

2. SPEAKER SECTION OF POWER AMPLIFIER
Turn the ignition off.
Disconnect the Power Amplifier harness connector.
Turn the ignition on.
Turn the radio on.
With the scan tool, erase the audio DTCs.
Cycle the ignition switch from off to on and wait 10 seconds.
With the scan tool, read DTC's.
Does the scan tool display ALL OUTPUTS SHORT?

Yes

- Go To3

No

- Replace the Power Amplifier.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

3. (+) CIRCUIT SHORTED TO GROUND
Turn the ignition off.
Disconnect the Power Amplifier harness connector.
Disconnect the Radio harness connector.
Measure the resistance between ground and any speaker (+) circuit.
Is the resistance below 1000.0 (1K) ohms?

Yes

- Repair the speaker (+) circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

No

- Go To4

4. (-) CIRCUIT SHORTED TO GROUND
Turn the ignition off.
Disconnect the Power Amplifier harness connector.
Disconnect the Radio harness connector.
Measure the resistance between ground and any speaker (-) circuit.
Is the resistance below 1000.0 (1K) ohms?

Yes

- Repair the speaker (-) circuit for a short to ground.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

No

- Go To5

5. SPEAKER (+) & (-) CIRCUITS SHORTED TOGETHER
Turn the ignition off.
Disconnect the Power Amplifier harness connector.
Disconnect the Radio harness connector.
Measure the resistance between each speaker (+) circuit and each speaker (-) circuit.
Is the resistance below 1000.0 (1K) ohms for any of the measurements?

Yes

- Repair the speaker circuits shorted together.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test

No

- Go To6

6. SPEAKER SECTION OF RADIO
If there are no possible causes remaining, view repair.

Repair

- Replace the Radio.
- Perform BODY VERIFICATION TEST - VER 1.Body Verification Test
