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 To 2

No

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

2. SPEAKER SECTION OF AMPLIFIER

Turn the ignition off.

Disconnect the Amplifier C2 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 To 3

No

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

3. (X53)(+) (X54)(+) CIRCUIT SHORTED TO GROUND





Turn the ignition off.

Disconnect the Amplifier C2 harness connector.

Disconnect the Radio (C1 on premium) harness connector.

Measure the resistance between ground and each radio (X53)(+) and (X54)(+) circuit.

Is the resistance below 1000.0 (1K) ohms?

Yes

- Repair the radio (X54) right or (X53) left (+) circuit for a short to ground.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test


No

- Go To 4

4. (X55)(-) (X56)(-) CIRCUIT SHORTED TO GROUND





Turn the ignition off.

Disconnect the Amplifier C2 harness connector.

Disconnect the Radio (C1 on premium) harness connector.

Measure the resistance between ground and each radio right and left (-) circuit.

Is the resistance below 1000.0 (1K) ohms?

Yes

- Repair the radio (X56) right or (X55) left (-) circuit for a short to ground.
- Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test

No

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