Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview
* Review Strategy Based Diagnosis for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions provides an overview of each diagnostic category.

Circuit/System Testing

1. 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.

2. Verify that the wireless headphones are set to the proper channel and are working properly.

• If the wireless headphones are not operating properly, go to Video Entertainment System Wireless Headphone Inoperative. Video Entertainment System Wireless Headphone Inoperative

3. Disconnect the J2 connector of the rear seat audio (RSA) control module. Connect a DMM between the suspect speaker output circuits (input to the RSA) from the radio. Turn ON the radio and verify there is AC voltage present.

• If AC voltage is not present, go to Speakers Inoperative - One or More. Speakers Inoperative - One or More

4. Disconnect the J1 harness connector from the RSA module. Verify that a test lamp illuminates between the RSA module B+ circuit terminal J1-5 and ground.

• If the test lamp does not illuminate, test the B+ circuit for a short to ground or an open/high resistance.

5. Test for less than 1.0 ohm of resistance between the ground circuit terminal J1-6 and ground

• If greater than the specified range, test the ground circuit for an open/high resistance.

• If all circuits test normal, replace the RSA module.
