Circuit/System Verification
Radio ON, verify clear audio is heard from each audio speaker with the RSA system OFF.
Circuit/System Testing
- Ignition OFF, disconnect the C1 harness connector at the rear seat audio (RSA) controller.
- 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. |
- 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. |
- 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. |
- If all circuits test normal, replace the rear seat audio controller.
