Diagnostic Fault Information





Circuit Description

The infrared transmitter is grounded and powered by the rear seat audio (RSA) module. When a key on the remote is pressed, the remote control sends an infrared message to 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, DVD playing, test for B+ between the infrared module control circuit terminal 4 and ground.

• If less than specified range, test the control circuit for a short to ground or an open/high resistance. If the circuit tests normal, replace the rear seat audio module.

4. Ignition ON, DVD playing, test for 0.75-2 volts between the remote infrared signal (+) circuit 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. Ignition ON, DVD playing, test for less than 1 volt between the remote infrared signal (-) circuit 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. Reconnect the harness connector at the infrared transmitter, and 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 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 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 and test for 300-330 MHz between the remote infra red signal (+) circuit 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
