Door Lock Operating Test
If there is continuity between door lock relay harness side connector B8 terminals No. 4 & 5, connect the battery voltage between terminals No. 4 & 5 and check operation. See Fig 1 . With 12 Volts connected to terminal No. 4 (Yellow/Blue wire) and ground connected to terminal No. 5 (Yellow wire), door locks should unlock. With 12 volts connected to terminal No. 5 (Yellow wire) and ground connected to terminal No. 4 (Yellow/Blue wire), door locks should lock. If door lock is inoperative in this test, inspection of door lock actuator should be made.
