Power and Ground Distribution: Testing and Inspection

1. Inspect Engine Room R/B Circuit




a. Remove the fuse from the junction block and inspect the connector on junction block side.
If the circuit is not as specified, inspect the circuits connected to other parts.







b. Remove the relay from the junction block and inspect the connector on junction block side.
If the circuit is not as specified, inspect the circuits connected to other parts.







c. Inspect Engine Room Junction Block Inner Circuit:
inspect the connector on junction block side.

HINT: Remove the junction block from the vehicle.

If the circuit is not as specified, replace it with junction block assembly.

HINT: The relay is built in engine room junction block. Also the relay is constructed with a relay block that is in the junction block as a unit. To disconnect the wire harness connecting with relay block is impossible. If the relay has a malfunction, replace it with junction block assembly wire harness together.








2. Inspect Cowl Side J/B LH Circuit








a. Remove the fuse from the junction block and inspect the connector on junction block side.
If the circuit is not as specified, inspect the circuits connected to other parts.




b. Remove the relay from the junction block and inspect the connector on junction block side.
If the circuit is not as specified, inspect the circuits connected to other parts.








3. Inspect Cowl Side J/B RH Circuit







a. Remove the fuse from the junction block and inspect the connector on junction block side.
If the circuit is not as specified, inspect the circuits connected to other parts.




Remove the relay from the junction block and inspect the connector on junction block side.
If the circuit is not as specified, inspect the circuits connected to other parts.
