DIAGNOSTIC PROCEDURES - POWER AMP SHUTDOWN - PREMIUM AUDIO SYSTEM
| TEST | ACTION | APPLICABILITY |
|---|---|---|
| 1 | Turn the ignition on. Turn the Radio on. With the DRBIII®, erase the audio DTC's. Cycle the ignition switch from off to on and wait 10 seconds. With the DRBIII®, read the audio DTC's. Does the DRBIII® display POWER AMP SHUTDOWN? Yes --> Go To 2 No --> Refer to appropriate SYSTEM WIRING DIAGRAMS article to help isolate a possible intermittent short. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 2 | Turn the ignition off. Disconnect the Power Amplifier harness connector. Turn the ignition on. Turn the radio on. With the DRBIII®, erase the audio DTCs. Cycle the ignition switch from off to on and wait 10 seconds. With the DRBIII®, read DTC's. Does the DRBIII® display POWER AMP SHUTDOWN? Yes --> Go To 3 No --> Replace the Power Amplifier. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 3 | Turn the ignition off. Disconnect the Power Amplifier harness connector. Disconnect the Radio C1 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 . No --> Go To 4 |
All |
| 4 | Turn the ignition off. Disconnect the Power Amplifier harness connector. Disconnect the Radio C1 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 . No --> Go To 5 |
All |
| 5 | Turn the ignition off. Disconnect the Power Amplifier harness connector. Disconnect the Radio C1 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 . No --> Go To 6 |
All |
| 6 | If there are no possible causes remaining, view repair. Repair Replace the Radio. Perform BODY VERIFICATION TEST - VER 1 . |
