If circuit is correct as specified, replace the relay.
Door Lock Solenoid
INSPECTION OF DOOR LOCK SOLENOID
INSPECT SOLENOID OPERATION
(a) Connect the positive (+) lead from the battery to terminal A-1. Connect the negative (—) lead to terminal A-3. Check that the solenoid operates locks direction.
(b) Check that there is no continuity between terminals B-1 and B-2.
(c) Connect the positive (+) lead from the battery to terminal 2. Connect the negative (—) lead to terminal A-3. Check that the solenoid operates locks direction.
(d) Check that there is continuity between terminals B-1 and B-2.
If there is no solenoid operation, replace the solenoid.
