1. Disconnect door harness connectors. Connect battery voltage to door harness connector terminals and
check operation. Apply battery voltage to connector terminal No. 6 and ground to terminal No. 8. See
Fig. 2 . Doors should lock.
2. Apply battery voltage to connector terminal No. 8 and ground to terminal No. 6. Doors should unlock. If
any one actuator does not operate, perform DOOR LOCK ACTUATOR TEST under COMPONENT
TESTS. If actuator is okay, check door harness. If all actuators are inoperative, check control unit harness
connector.
