Circuit/System Description
|
The infrared remote signal is used to transmit signals from the rear seat entertainment (RSE) remote control via pulse width modulated (PWM) signals to the radio. When a key on the remote is pressed, the remote control sends an infrared message to the infrared receiver located in the DVD display. The infrared receiver converts these infrared signals into a frequency and sends the message to the radio to perform the appropriate function. Both seatback displays contain receivers for the infrared remote, which are connected to common (+) and (-) signal circuits to the radio.

Circuit/System Verification
|
|
1.
|
Ignition ON, Radio ON, DVD playing, verify that the Rear Seat Entertainment System audio/video functions are working properly.
|
|
3.
|
Verify that all remote control functions are working properly.
|
|
4.
|
If one or more, but not all of the functions on the remote control is inoperative, replace the remote control.
|
|
5.
|
If all functions are inoperative on the remote control, test or replace the batteries.
|
|
6.
|
Verify that all remote control functions are working properly pointing at the left and right DVD display while holding the remote control 8-10 inches from each display.
|
|
1.
|
Ignition OFF, disconnect the harness connectors at both of the P22 seatback video displays.
|
|
2.
|
Ignition OFF, scan tool disconnected, open driver door, wait two minutes. Test for less than 1 Ω between the infrared remote signal (-) circuits terminal 13 and ground.
|
|
3.
|
If greater than the specified range, test the signal (-) circuit for an open/high resistance. If the circuits test normal, replace the A11 radio.
|
|
4.
|
Ignition ON, DVD playing, test for 1-4 V between the infrared remote signal (+) circuit terminal 12 and ground.
|
|
5.
|
If less than specified range, test the signal (+) circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the A11 radio.
|
|
6.
|
If greater than specified range, test the signal (+) circuit for a short to voltage. If the circuit tests normal, replace the A11 radio.
|
|
7.
|
Ignition OFF, reconnect the harness connector at the P22E driver seatback video display.
|
|
8.
|
Ignition ON, DVD playing, test for 1-4 V between the infrared remote signal (+) circuit terminal 12 and ground at the P22F passenger seatback video display.
|
|
9.
|
If not within the specified range, replace the P22E driver seatback video display.
|
|
10.
|
If all circuits test normal, replace the P22F passenger seatback video display.
|
Perform the
Diagnostic Repair Verification
after completing the diagnostic procedure.
