Circuit/System Testing


Important: Center the balance and fade adjustment on the radio. If adjustment of the fade and balance eliminates the concern, review the operation of the radio with the customer.


1. Turn ON the wireless headphones. Verify the power indicator lamp on the wireless headphone illuminates.

• If the power indicator lamp does not illuminate on the wireless headphones check or replace the wireless headphone batteries. If the batteries are OK replace the wireless headphones.

2. Radio ON, operate the rear seat audio (RSA). Set both wireless headphones to the proper channel to hear RSA. Adjust the volume up on both wireless headphones. Verify that only one set of wireless headphones operates properly.

• If only one set of wireless headphones do not have audio, replace the suspect wireless headphone set.

3. With a DMM, verify there is B+ at the video display infra-red supply voltage circuit when the RSA is activated.

• If B+ is not present, test for a open or short to power on the infra-red supply voltage circuit. If the infra-red supply voltage circuit tests normal, replace the rear seat audio controller.

4. At the video display connector harness, test for AC voltage between the low reference circuit and the left and right infra-red audio signal circuits. Verify there is AC voltage with the RSA activated.

• If AC voltage is not present, test for an open, short to ground or short to B+ on the low reference and both left and right infra-red audio signal circuits. If the low reference and audio signals test normal replace the rear seat audio controller.


• If AC voltage is present, replace the video display
