Diagnostic Fault Information
Circuit/System Description
The audio/video jacks allow the connection of audio and video signals from an auxiliary device such as a camcorder, video game console or MP3 player to the rear seat entertainment system. The middle jack is for left audio (white), the right jack is for right audio (red), and the left jack is for video (yellow). The system requires standard RCA cables to connect your auxiliary device to the RCA jacks. The auxiliary audio and video circuits are connected to the radio.
Diagnostic Aids
Verify the external audio or video device is operating normally before performing this diagnostic procedure.

Circuit/System Testing
1. Ignition OFF, disconnect the X3 harness connector at the radio.
2. Ignition ON, test for less then 1 volt between the appropriate signal circuit terminals listed below and ground.
* Auxiliary audio left signal (+) - terminal 1
* Auxiliary audio right signal (+) - terminal 2
* Auxiliary audio drain wire (-) - terminal 9
* Auxiliary video signal (+) - terminal 8
* Auxiliary video drain wire (+) - terminal 16
• If greater then specified range, test the circuit for a short to voltage.
3. Test for infinite resistance between the terminals listed below and ground.
* Auxiliary audio left signal (+) - terminal 1
* Auxiliary audio right signal (+) - terminal 2
* Auxiliary audio drain wire (-) - terminal 9
* Auxiliary video signal (+) - terminal 8
* Auxiliary video drain wire (+) - terminal 16
• If less then the specified value, test the circuit for a short to ground.
4. Test for less then 5 ohm between the terminals on the radio X3 harness connector and the external terminals on the audio/video adaptor listed below:
* Auxiliary audio left signal (+) - terminal 1 and the left audio jack center terminal (white).
* Auxiliary audio right signal (+) - terminal 2 and the right audio jack center terminal (red).
* Auxiliary audio drain wire (-) - terminal 9 and the outside of both the left audio jack (white), and the right audio jack (red).
* Auxiliary video signal (+) - terminal 8 and the video jack center terminal (yellow).
* Auxiliary video drain wire (+) - terminal 16 and the outside of the video jack (yellow).
• If greater then the specified value, test the circuit for an open/high resistance. If the circuit tests normal, replace the adaptor.
5. If all circuits test normal, replace the radio.
Repair Instructions
Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
* Auxiliary Audio/Video Input Control Replacement (Service and Repair)
* Control Module References (Programming and Relearning) for Radio replacement, setup, and programming
