Front left side door:
INSPECT 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.




Front right side door:
INSPECT DOOR LOCK MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 5 and the negative (-) lead to terminal 6, 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.




Rear left side door:
INSPECT 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.




Rear right side door:
INSPECT DOOR LOCK MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 3 and the negative (-) lead to terminal 4, 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.

Front left side door:
INSPECT PTC THERMISTOR OPERATION (Using an ammeter)




a. Connect the negative (-) lead from the battery to terminal 2.
b. Connect the positive (+) lead from the ammeter to terminal 1 and the negative (-) lead to battery negative (-) terminal, 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, connect the positive (+) lead from the battery to terminal 2 and the negative (-) lead to terminal 1, and check that the door lock moves to the LOCK position.
If operation is not as specified, replace the door lock assembly.
