Diagnostic Fault Information
Circuit Description
The rear seat entertainment (RSE) system utilizes the vehicle radio to play DVD movies and transmit video signals to the rear digital video disc (DVD) display. When the radio is turned ON, the DVD display receives a voltage signal from the radio via the entertainment remote enable signal circuit indicating the system status. The video high and low signal circuits are used to transmit the DVD images to the rear DVD display. The video high (+) voltage will vary as the brightness and the speed of the image varies. A typical voltage reading for the video high (+) is 1 to 2.5V at the disconnected at the video display.

Circuit/System Verification
1. Ignition ON, vehicle in Park. Operate the DVD entertainment system using several known good DVD disks.
• If the radio does not display the DVD, replace the radio.
2. RSE ON, observe the rear DVD screen. Verify the rear video display operates normally.
• If the rear video display does not operate normally, refer to circuit testing.
Circuit/System Testing
1. Ignition OFF, disconnect the harness connector at the appropriate DVD display.
2. Ignition OFF, test for less than 5.0 ohms between the ground circuit terminals listed below and ground.
* Ground terminal 6
* Ground terminal 5 (DNU)
• If greater than specified range, test the ground circuit for an open/high resistance.
3. Ignition ON, DVD playing, test for B+ between the entertainment remote enable B+ circuit terminal 8 and ground.
• If less than specified value, test the B+ circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
4. Ignition ON, test for B+ between the battery positive voltage circuit terminal 7 and ground.
• If less than specified value, test the voltage supply circuit for a short to ground or an open/high resistance.
5. Ignition ON, DVD playing, test for 1-8 volts between the video bright control circuit terminal 9, and ground.
• If greater then specified range, test the control circuit for a short to voltage. If the circuit tests normal, replace the radio.
• If less then specified range, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
6. Ignition ON, DVD playing, test for 0.1-3.0 volts between the video mode signal circuit terminal 10, and ground.
• If greater then specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
• If less then specified range, test the signal circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
7. Ignition ON, DVD playing, test for 1-3 volts between the video signal (+) circuit terminal 1, and ground.
• If greater then specified range, test the control circuit for a short to voltage. If the circuit tests normal, replace the radio.
• If less then specified range, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the radio.
8. If all circuits test normal, replace the DVD display.
Repair Instructions
Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
* Video Display Replacement (Second Row) (Service and Repair)
* Control Module References (Programming and Relearning) for radio replacement, setup, and programming
