Diagnostic Fault Information
Circuit Description
The infrared transmitter is powered by the retained accessory power (RAP) relay. When a key on the remote is pressed, the remote control sends an infrared message to the infrared transmitter. The infrared transmitter will convert these infrared signals into a frequency and send that message to the radio via the remote infrared signal circuits (+) and (-).

Circuit/System Testing
Important: Test or replace the remote batteries before performing the circuit/system test.
1. Ignition OFF, disconnect the harness connector at the infrared transmitter.
2. Ignition OFF, test for less than 5.0 Ohms between the ground circuit terminal 12 and ground.
• If greater than specified range, test the ground circuit for an open/high resistance.
3. Ignition ON, test for B+ between the accessory voltage circuit terminal 4 and ground.
• If less than specified value, test the accessory voltage circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the rear seat audio module.
4. DVD playing, test for 0.75-2 volts between the remote infra red signal (+) circuit terminal 8 and ground.
• 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 radio.
• If greater than specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
5. Test for less than 1 volt between the remote infra red signal (-) circuit terminal 16 and ground.
• If greater than specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the radio.
6. Ignition OFF, reconnect the harness connector at the infrared transmitter, disconnect the X3 harness connector at the radio.
7. Ignition ON, DVD playing, test for 4-5.5 mV AC between the remote infra red signal (+) circuit terminal 5 and ground.
• 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 infrared transmitter.
• If greater than specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the infrared transmitter.
8. Ignition ON, DVD playing, test for 4-6 mV AC between the remote infra red signal (-) circuit terminal 13 and ground.
• 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 infrared transmitter.
• If greater than specified range, test the signal circuit for a short to voltage. If the circuit tests normal, replace the infrared transmitter.
9. Ignition ON, DVD playing, press any button on the remote control aimed at the infrared transmitter. Test for 300-330 MHz between the remote infra red signal (+) circuit terminal 5 and ground.
• If not within the specified range, replace the remote control.
10. If all circuits test normal, replace the radio.
Repair Instructions
Perform the Diagnostic Repair Verification (Verification Tests) after completing the diagnostic procedure.
* Audio System Transceiver Module Replacement (Audio System Transceiver Module Replacement)
* Control Module References (Programming and Relearning) for Radio replacement, setup, and programming
