Component Tests and General Diagnostics

1. INSPECT DRIVER'S DOOR LOCK CONTROL SWITCH CONTINUITY




If continuity is not as specified, replace the switch.




2. INSPECT PASSENGER'S DOOR LOCK CONTROL SWITCH CONTINUITY




If continuity is not as specified, replace the switch.




3. INSPECT FRONT DOOR KEY LOCK AND UNLOCK SWITCH CONTINUITY




If continuity is not as specified, replace the switch.




4. INSPECT BACK DOOR KEY LOCK AND UNLOCK SWITCH CONTINUITY




If continuity is not as specified, replace the switch.




5. INSPECT FRONT DOOR UNLOCK DETECTION SWITCH CONTINUITY




If continuity is not as specified, replace the switch.




6. INSPECT BACK DOOR UNLOCK DETECTION SWITCH CONTINUITY




If continuity is not as specified, replace the switch.

7. INSPECT FRONT DOOR LOCK MOTOR OPERATION




a. Connect the positive (+) lead from the battery to terminal 3 and the negative (-) lead to terminal 2, and check that the door lock link moves to UNLOCK position.




b. Reverse the polarity and check that the door lock link moves to LOCK position.
If operation is not as specified, replace the door lock assembly.

8. INSPECT SLID DOOR LOCK MOTOR OPERATION




a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the door lock link moves to UNLOCK position.




b. Reverse the polarity and check that the door lock link moves to LOCK position.
If operation is not as specified, replace the door lock assembly.

9. INSPECT BACK DOOR LOCK MOTOR OPERATION




a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the door lock link moves to UNLOCK position.




b. Reverse the polarity and check that the door lock link moves to LOCK position.
If operation is not as specified, replace the door lock assembly.

10. INSPECT INTEGRATION RELAY OPERATION

HINT: When the relay circuit is as specified, inspect the door lock signal.




a. Connect the positive (+) lead from the voltmeter to terminal 1 and the negative (-) lead to terminal 9.
b. Set the door lock control switch to UNLOCK and check that the voltage rises from 0 V to battery positive voltage for approximately 0.2 seconds.




c. Reverse the polarity of the voltmeter leads.
d. Set the door lock control switch to LOCK and check that the voltage rises from 0 V to battery positive voltage for approximately 0.2 seconds.
If operation is not as specified, replace the relay.
