1. INSPECT POWER AMPLIFIER CIRCUIT
Disconnect the connector from the power amplifier and inspect the connector on the wire harness side, as shown.
If circuit is not as specified, inspect the circuits connected to other parts.








2. INSPECT CD AUTO CHANGER CIRCUIT
Disconnect the connectors from the controller and inspect the connector on the wire harness side, as shown.
If circuit is not as specified, inspect the circuits connected to other parts.
