Diagnostic Fault Information
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
Note: Test or replace the remote control batteries before performing the circuit/system verification.
1. Ignition ON, radio ON, DVD playing.
2. Verify that the Rear Seat Entertainment System audio/video operates.
• If the Rear Seat Entertainment System is inoperative.
Refer to Video Entertainment System Malfunction Video Entertainment System Malfunction.
• If the Rear Seat Entertainment System operates.
3. Verify that all remote control functions operate.
• If some, but not all, controls operate.
Replace the remote control.
• If all controls are inoperative.
1. Replace the remote control.
2. Verify that all remote control functions are working properly.
• If all controls are inoperative.
Refer to Circuit/System Testing
• If all controls operate and perform the correct function.
3. All OK.
• If all controls operate and perform the correct function.
4. All OK.
Circuit/System Testing
1. Ignition OFF and all vehicle systems OFF. It may take up to 2 minutes for all vehicle systems to power down
2. Disconnect the harness connectors at both of the P22 seatback video displays.
3. Test for less than 10 ohms between the signal (-) circuits terminal 13 and ground at each display.
• If 10 ohms or greater
1. Ignition OFF, disconnect the X2 connector at the A11 radio.
2. Test for less than 2 ohms in the signal circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the A11 radio.
• If less than 10 ohms
4. Ignition ON, radio ON, DVD playing.
5. Test for 1-4 V between the signal (+) circuit terminal 12 and ground at each display.
• If less than 1 V
1. Ignition OFF, disconnect the X2 harness connector at the A11 radio.
2. Test for infinite resistance between the signal circuit and ground.
• If less than infinite resistance, repair the short to ground on the circuit.
• If infinite resistance
3. Test for less than 2 ohms in the signal circuit end to end.
• If 2 ohms or greater, repair the open/high resistance in the circuit.
• If less than 2 ohms, replace the A11 radio.
• If greater than 4 V
1. Ignition OFF, disconnect the X2 harness connector at the A11 radio. Ignition ON.
2. Test for less than 1 V between the signal circuit and ground.
• If 1 V or greater, repair the short to voltage on the circuit.
• If less than 1 V, replace the A11 radio.
• If between 1-4 V
6. Ignition OFF. Connect the harness connector at the P22E driver seatback video display.
7. Ignition ON, radio ON, DVD playing.
8. Test for 1-4 V between the signal (+) circuit terminal 12 and ground at the P22F passenger seatback video display.
• If less than 1 V
Test or replace the P22E driver seatback video display
• If greater than 4 V
Test or replace the P22E driver seatback video display
• If between 1-4 V
9. Test or replace the P22F passenger seatback video display.
