9. Front 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 termi-
nal 3 and the negative (-) lead to battery negative (-) ter-
minal, and check that the current changes from approxi-
mately 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 3, and check that the door lock moves to
the LOCK position.
If operation is not as specified, replace the door lock assembly.
10. Rear 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 termi-
nal 3 and the negative (-) lead to battery negative (-) ter-
minal, and check that the current changes from approxi-
mately 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 (-)
