Diagnostic Fault Information






Circuit/System Description

The audio/video adaptor allows the connection of audio and video signals from an external 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 external 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

Important:
Verify the DVD player in the radio is operating normally before performing this diagnostic procedure. If there is any problems with operating the DVD player, refer to Symptoms - Entertainment Symptoms - Entertainment


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 inside of the center (white) jack

* Auxiliary audio right signal (+) - terminal 2 and the inside of the right (red) jack

* Auxiliary audio drain wire (-) - terminal 9 and the outside of both the center (white), and the right (red) jacks

* Auxiliary video signal (+) - terminal 8 and the inside of the left (yellow) jack

* Auxiliary video drain wire (+) - terminal 16 and the outside of the left (yellow) jack

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.
