3 and the negative (−) lead to terminal 7, check that the
door lock link moves to UNLOCK position.
(b) Remove the polarity, check that the door lock link moves
to LOCK position.
If operation is not as specified, replace the door lock assembly.
5. INSPECT PASSENGER’S DOOR LOCK MOTOR OP-
ERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative (−) lead to terminal 6, check that the
door lock moves to UNLOCK position.

power window signal.
9. Door Lock Signal:
INSPECT DOOR LOCK CONTROL RELAY
HINT:
When the relay circuit is as specified, inspect the door lock sig-
nal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter to termi-
nal 1 and the negative (−) lead to terminal 6.
(c) Set the door lock control switch to UNLOCK, check that
the voltage rises from 0 V to battery positive voltage for
approximately 0.2 seconds.

(d) Reverse the polarity of the voltmeter leads.
(e) Set the door lock control switch to LOCK, 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. Key−off Power Window Signal:
INSPECT DOOR LOCK CONTROL RELAY
HINT:
When the relay circuit is as specified, inspect the key−off power
window signal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter to termi-
nal 5 and the negative (−) lead to terminal 11.
(c) Close the door with ignition switch turned to LOCK or
ACC, check that the meter needle indicates battery posi-
tive voltage.
(d) Open the door, check that the meter needle indicates 0 V.
(e) Turn the ignition switch ON, check that the meter needle
indicate battery positive voltage again.
If operation is not as specified, replace the relay.
