Circuit/System Verification

Radio ON, verify clear audio is heard from each audio speaker.

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

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

3. Ignition ON, test for B+ between the voltage supply circuit terminal 5 and ground.

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

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