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