Radio ON, verify clear audio is heard from each audio speaker with the RSA system OFF.

1. Ignition OFF, disconnect the C1 harness connector at the rear seat audio (RSA) controller.
2. Ignition ON, test for less than 1 volt betweent the ground circuit terminal 6 and ground.

⇒	If greater than the specified range, test the ground circuit for a short to voltage.

3. Ignition OFF, test for less than 5 ohms between the ground circuit terminal 6 and ground.

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

4. Ignition ON, radio ON, test for battery voltage between the battery positive voltage circuit terminal 5 and ground.

⇒	If less than the specified range, test the voltage reference circuit for a short to ground or an open/high resistance.

5. If all circuits test normal, replace the rear seat audio controller.

Perform the Diagnostic Repair Verification after completing the diagnostic procedure.
