|
The rear seat entertainment (RSE) system utilizes the vehicle radio to play DVD movies and transmit video signals to the digital video disc (DVD) seatback displays. When the radio is turned ON, the DVD seatback displays receive a voltage signal from the radio via the remote enable signal circuit indicating the system status. Discreet output circuits from the radio are used to transmit the DVD images to each of the DVD seatback displays. The radio utilizes discreet mode control circuits to each display to control the screen display mode via a pulse width modulated signal. A single brightness control circuit is used by the radio to control the display screen brightness for both displays via a pulse width modulated signal.

Circuit/System Verification
|
|
1.
|
Ignition ON, Radio ON, DVD playing, verify that the Rear Seat Entertainment System audio and video functions are working properly.
|
|
2.
|
If the Rear Seat Entertainment System is inoperative refer to Circuit/System Testing.
|
|
3.
|
Verify that all remote control functions are working properly.
|
|
5.
|
Verify that each headphone is working properly.
|
|
1.
|
Ignition OFF, disconnect the harness connector at the appropriate DVD display.
|
|
2.
|
Test for less than 10 Ω between the ground circuit terminals listed below and ground.
|
|
3.
|
If greater than the specified range, test the ground circuit for an open/high resistance.
|
|
4.
|
Verify a test lamp illuminates between the B+ circuit terminal 1 and ground.
|
|
5.
|
If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.
|
|
6.
|
Ignition ON, radio ON, verify a test lamp illuminates between the remote enable control circuit terminal 2 and and ground.
|
|
7.
|
If the test lamp does not illuminate, test the remote enable circuit for a short to ground or an open/high resistance.
|
|
8.
|
DVD playing, test for 190-210 HZ DC between the video bright control circuit terminal 16 and ground.
|
|
9.
|
If not within the specified range, test the control circuit for a short to voltage, short to ground, or an open/high resistance. If the circuit tests normal, replace the radio.
|
|
10.
|
Command the rear screen video mode to normal, test for 190-210 HZ DC between the video mode signal circuit terminal 15 and ground.
|
|
11.
|
If not within the specified range, test the control circuit for a short to voltage, short to ground, or an open/high resistance. If the circuit tests normal, replace the radio.
|
|
12.
|
DVD playing, test for 1-3 V between the control circuit terminals listed below and ground.
|
|

|
•
|
Video Signal (-) - terminal 10
|
|
13.
|
If greater then specified range, test the control circuit for a short to voltage. If the circuit tests normal, replace the radio.
|
|
14.
|
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.
|
|
15.
|
If all circuits test normal, replace the DVD display.
|
Perform the
Diagnostic Repair Verification
after completing the diagnostic procedure.
