Circuit/System Verification

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

If audio is inoperative from one or all speakers, refer to Speaker Malfunction (Speaker Malfunction).

Circuit/System Testing

1. Ignition OFF, disconnect the X1 harness connector at the rear seat audio (RSA) controller.
2. 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.

3. 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 circuit for a short to ground or an open/high resistance.

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