On-Vehicle Inspection of Relay Circuit
Disconnect the relay connect and inspect the connector on the wire harness side as shown in the table below. Connect the positive (+) lead from the battery to terminal 4 and the negative (-) lead to terminal 1, and check that the solenoid operates lock direction. If circuit is correct, replace the relay.
