Component Tests and General Diagnostics

INSPECTION

1. Master switch:
INSPECT DRIVER'S DOOR LOCK CONTROL SWITCH CONTINUITY
If continuity is not as specified, replace the switch.

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

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

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

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

6. Driver's 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.

7. Passenger's 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.

8. INSPECT DRIVER'S DOOR PTC THERMISTOR OPERATION

a. Connect the negative (-) lead from the battery to terminal 2.
b. Connect the positive (+) lead from the ammeter to terminal 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.

9. INSPECT PASSENGER'S DOOR PTC THERMISTOR OPERATION

a. Connect the negative (-) lead from the battery to terminal 6.
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 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 6 and the negative (-) lead to terminal 5, and check that the door lock moves to the LOCK position.
If operation is not as specified, replace the door lock assembly.

10. INSPECT DRIVER'S DOOR PTC THERMISTOR OPERATION

a. Connect the positive (+) lead from the battery to terminal 1 and the negative (-) lead to terminal 2.
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 operation is not as specified, replace the door lock assembly.

11. INSPECT PASSENGER'S DOOR PTC THERMISTOR OPERATION

a. Connect the positive (+) lead from the battery to terminal 5 and the negative (-) lead to terminal 6.
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.

12. INSPECT BACK DOOR LOCK MOTOR OPERATION
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.
If operation is not as specified, replace.
