Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Circuit/System Testing
The infrared transmitter module contains infrared transmitters for the wireless headphones and the infrared receiver for the video system remote control. The infrared transmitter module processes the signal from the remote devices and sends the requests to the radio via the remote infrared signal circuits. If the display is in the closed position, the infrared signals will not be available for the operation of the wireless headphones and the remote control.
- Ignition ON, rear entertainment system ON, verify the system works with a known good remote.
- If the known good remote operates properly, replace the suspect remote.
- Operate the radio and verify the wireless headphones operate properly.
- If the wireless headphones do not operate properly, refer to Video Entertainment System Wireless Headphone Inoperative .
- If all circuits test normal, replace the infrared transmitter module.
