- If the known good remote operates properly, replace the suspect remote.
- Operate the radio and turn on the rear seat audio (RSA). Verify the remote headphones operate normally.
- If the remote headphones do not operate properly, go to Video Entertainment System Wireless Headphone Inoperative .
- Install a scan tool, monitor the button presses in the radio data display. Verify the radio responds to the remote when the buttons are pressed.
