INSPECTION




1. INSPECT ENGINE ROOM JUNCTION BLOCK CIRCUIT




a. Remove the fuse from the junction block and inspect the connection on the junction block side.
If the circuit is as specified, inspect the circuits connected to other parts.




b. Remove the relay from the junction block and inspect the connector on the junction block side.




If the circuit is as specified, inspect the circuits connected to other parts.







2. INSPECT FUSIBLE LINK BLOCK CIRCUIT
Remove the fuse from the fusible link and inspect the connector on the fusible link side.
If the circuit is as specified, inspect the circuits connected to other parts.







3. INSPECT RELAY BLOCK NO.2 (Inside Engine Room Junction Block) CIRCUIT
a. Remove the fuse from the relay block No.2 and inspect the connector on the relay block side.
If the circuit is as specified, inspect the circuit connected to other parts.
b. Remove the relay from the relay block No.2 and inspect the connector on the relay block side.
If the circuit is as specified, inspect the circuit connected to other parts.




4. INSPECT ENGINE ROOM RELAY BLOCK NO.3 CIRCUIT




a. Remove the fuse from the engine room relay block No.3 and inspect the connector on the relay block side.
If the circuit is as specified, inspect the circuit connected to other parts.




b. Remove the relay from the engine room relay block No.3 and inspect the connector on the relay block side.
If the circuit is as specified, inspect the circuit connected to other parts.










5. INSPECT INSTRUMENT PANEL JUNCTION BLOCK CIRCUIT
a. Remove the fuse from the instrument panel junction block and inspect the connector on the junction block side.




b. Remove the relay from the instrument junction block and inspect the connector on the junction block side.







If the circuit is as specified, inspect the circuit connected to other parts.

6. INSPECT RELAY BLOCK NO.1 CIRCUIT
