15. INSPECT LUGGAGE COMPARTMENT DOOR OPENER MOTOR CIRCUIT

16. INSPECT DOOR LOCK MOTOR OPERATION
a. Connect the positive (+) lead from the battery to terminal 2 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 move to LOCK position.
If operation is not as specified, replace the door lock assembly.

17. Using an ammeter:
INSPECT POWER DOOR LOCK MOTOR PTC THERMISTOR OPERATION

a. Connect the positive (+) lead from the battery to terminal 2.
b. Connect the positive (+) lead from the ammeter to terminal 5 and the negative (-) lead to battery negative (-) terminal, and check that the current changes from approximately 3.2 ampere to less than 0.5 ampere with 20 to 70 seconds.

c. Disconnect the leads from terminals.
d. Approximately 60 seconds later, connect the positive (+) lead from the battery to terminal 5 and the negative (-) lead to terminal 2, and check that the door lock moves to LOCK position.
If operation is not as specified, replace the door lock assembly.

18. Using an ammeter with a current-measuring probe:
INSPECT POWER DOOR LOCK MOTOR PTC THERMISTOR OPERATION

a. Connect the positive (+) lead from the battery to terminal 2 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 ampere to less than 0.5 ampere within 20 to 70 seconds.

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