INSPECTION







1. INSPECT DRIVER SIDE DOOR LOCK CONTROL SWITCH CONTINUITY
If the continuity is not as specified, replace the switch.







2. Drive side door:
INSPECT DOOR KEY LOCK AND UNLOCK SWITCH CONTINUITY
If the continuity is not as specified, replace the switch.







3. Passenger side door:
INSPECT DOOR KEY LOCK AND UNLOCK SWITCH CONTINUITY
If the continuity is not as specified, replace the switch.







4. Driver side door:
INSPECT DOOR UNLOCK DETECTION SWITCH CONTINUITY
If the continuity is not as specified, replace the switch.







5. Passenger side door:
INSPECT DOOR UNLOCK DETECTION SWITCH CONTINUITY
If the continuity is not as specified, replace the switch.




6. Driver side door:
INSPECT DOOR LOCK MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 6 and the negative (-) lead to terminal 5, 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 the operation is not as specified, replace the door lock assembly.




7. Passenger side door:
INSPECT DOOR LOCK MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, 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 the operation is not as specified, replace the door lock assembly.

8. INSPECT DRIVER'S DOOR PTC THERMISTOR OPERATION




a. Connect the negative (-) lead from the ammeter to terminal 6, and the positive (+) lead to negative terminal of the battery.
b. Connect the negative (-) lead from the battery to terminal 5.
c. Check that the current changes from approximately 3.2 A to less than 0.5 A within 20 to 70 seconds.





d. Disconnect the leads from terminals.
e. Approximately 60 seconds later, connect the positive (+) lead from the battery to terminal 5 and the negative (-) lead to terminal 6, and check that the door lock moves to the LOCK position.
If the operation is not as specified, replace the door lock assembly.

9. INSPECT PASSENGER SIDE DOOR PTC THERMISTOR OPERATION




a. Connect the negative (-) lead from the ammeter to terminal 2, and the positive (+) lead to negative terminal of the battery.
b. Connect the negative (-) lead from the battery to terminal 1.
c. Check that the current changes from approximately 3.2 A to less than 0.5 A within 20 to 70 seconds.




d. Disconnect the leads from terminals.
e. Approximately 60 seconds later, connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2, and check that the door lock moves to the LOCK position.
If the operation is not as specified, replace the door lock assembly.

10. INSPECT DRIVER SIDE DOOR PTC THERMISTOR OPERATION




a. Connect the positive (+) lead from the battery to terminal 6 and the negative (-) lead to terminal 5.
b. Attach a current-measuring probe to either the positive (+) lead or the negative (-) lead, and check that the current changes from approximately 3.2 A to less than 0.5 A within 20 to 70 seconds.




c. Disconnect the leads from terminals.
d. Approximately 60 seconds later, reverse the polarity, and check that the door lock moves to the LOCK position.
If the operation is not as specified, replace the door lock assembly.

11. INSPECT PASSENGER SIDE DOOR PTC THERMISTOR OPERATION




a. Connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1.
b. Attach a current-measuring probe to either the positive (+) lead or the negative (-) lead, and check that the current changes from approximately 3.2 A to less than 0.5 A within 20 to 70 seconds.




c. Disconnect the leads from terminals.
d. Approximately 60 seconds later, reverse the polarity, and check that the door lock moves to the LOCK position.
If the operation is not as specified, replace the door lock assembly.
