6. INSPECT MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
3 and the negative (±) lead to terminal 2, and check that
the door lock link moves to UNLOCK position.
(b) Remove 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. Using an ammeter:
INSPECT PTC THERMISTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
3.
(b) Connect the positive (+) lead from the ammeter to termi-
nal 2 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.
8. Using an ammeter with a current±measuring probe:
INSPECT PTC THERMISTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
3 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 cur-
rent 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.

INSPECT INTEGRATION RELAY (Type B) OPERATION
HINT:
When the relay circuit is as specified, inspect the door lock sig-
nal.
(a) Connect the positive (+) lead from the voltmeter to termi-
nal A12 and the negative (±) lead to terminal A25.
(b) Set the door lock control switch to UNLOCK and check
that the voltage rises from 0 V to battery positive voltage
for approximately 0.2 seconds.
(c) Reverse the polarity of the voltmeter leads.
(d) Set the door lock control switch to LOCK and check that
the voltage rises from 0 V to battery positive voltage for
approximately 0.2 seconds.
If operation is not as specified, replace the relay.
10. Door lock signal:
INSPECT INTEGRATION RELAY (Type C) OPERATION
HINT:
When the relay circuit is as specified, inspect the door lock sig-
nal.
(a) Connect the positive (+) lead from the voltmeter to termi-
nal A6 and the negative (±) lead to terminal A7.
(b) Set the door lock control switch to UNLOCK and check
that the voltage rises from 0 V to battery positive voltage
for approximately 0.2 seconds.
(c) Reverse the polarity of the voltmeter leads.
(d) Set the door lock control switch to LOCK and check that
the voltage rises from 0 V to battery positive voltage for
approximately 0.2 seconds.
If operation is not as specified, replace the relay.
