Diagnostic Procedure
ALL OUTPUTS SHORT SYMPTOM CHART
| 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 ALL OUTPUTS SHORT? Yes --> Go To 2 No --> Refer to SYSTEM WIRING DIAGRAMS located in the service information to help isolate a possible short. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 2 | Turn the ignition off. Disconnect the Amplifier C2 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 ALL OUTPUTS SHORT? Yes --> Go To 3 No --> Replace the Amplifier in accordance with the service information. Perform BODY VERIFICATION TEST - VER 1 . |
All |
| 3 | 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 right or left (+) circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 4 |
All |
| 4 | 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 right or left (-) circuit for a short to ground. Perform BODY VERIFICATION TEST - VER 1 . No --> Go To 5 |
All |
| 5 | Turn the ignition off. Disconnect the Amplifier C2 harness connector. Disconnect the Radio (C1 on premium) harness connector. Measure the resistance between each radio (+) circuit and each radio (-) circuit. Is the resistance below 1000.0 (1K) ohms for any of the measurements? Yes --> Repair the radio 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 . |
