Diagnostic Fault Information





Circuit Description

The infrared transmitter is located at the bottom of the monitor. When listening to the headphones, the infrared transmitter sends an infrared signal to the headphones. The audio that is sent from the DVD player to the radio is a varying AC voltage. The audio from the radio when tuned to XM(TM) can be over the audio from the DVD or CD when using the wired headphones plugged into the rear seat audio (RSA). This is considered normal operation.

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 terminal 7 and ground.

• If greater than specified range, test the ground circuit for an open/high resistance.

3. Ignition ON, test for B+ between the B+ circuit terminal 9 and ground.

• If less than specified value, test the B+ circuit for a short to ground or an open/high resistance.

4. If all circuits test normal, replace the DVD player.

Repair Instructions

Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
