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 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.
