- When Monitored:
Ignition in RUN and IOD fuse installed.

- Set Condition:
The radio has sensed a short on the output for more than 10 seconds.





1. DETERMINE FAULT
1. Turn the ignition on.
2. Turn the Radio on.
3. With the scan tool, erase the audio DTC's.
4. Cycle the ignition switch from off to on and wait 10 seconds.
5. 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 located to help isolate a possible intermittent short.
- Perform BODY VERIFICATION TEST. Body Verification Test

2. SPEAKER SECTION OF POWER AMPLIFIER
