2. INSPECT MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to ter-
minal 1 and negative (±) lead to terminal 2, check
that the motor turns.
(b) Connect the positive (+) lead from the battery to ter-
minal 2 and negative (±) lead to terminal 1, check
that the motor turns the opposite way.
If operation is not as specified, replace the motor. (b) With the window in the full closed position, hold the
switch in ºDOWNº and check that the window begins
to descend within 60 seconds.

HINT: When the relay circuit is as specified, inspect the
door lock signal.
(a) Connect the connector to the relay.
(b) Connect the positive (+) lead from the voltmeter
to terminal 3 and the negative (±) lead to the ter-
minal 4.
(c) Set the door lock manual switch to UNLOCK,
check
that the voltage rises from 0 volts to battery volt-
age for approximately 0.2 seconds.

INSPECTION OF RELAY
(Relay Circuit)
Disconnect the connector from the relay and inspect the
connector on the wire harness side as shown in the chart.
If circuit is as specified, inspect the door lock signal.

INSPECTION OF DOOR LOCK
SOLENOID
1. INSPECT SOLENOID OPERATION
(Front and Rear door)
(a) Connect the positive (+) lead from the battery to
terminal 4 and negative(±) lead to terminal 3, check
that the solenoid operation in the lock (Pull) direction.
(b) Check that there is no continuity between terminals
1 and 2.
(c) Connect the positive (+) lead from the battery to termi-
nal 3 and negative (±) lead to terminal 4, check that
the solenoid operation in the unlock (Push) direction.
(d) Check that there is continuity between terminals 1
and 2.
If operation is not as specified, replace the solenoid.
(c) Connect the positive (+) lead from the battery to ter-
minal 4 and negative (±) lead to terminal 2, check that
the solenoid operation in the unlock (Push) direction.
(d) Check that there is continuity between terminals 1
and 3.
If operation is not as specified, replace the solenoid. (Back door)
(a) Connect the positive (+) lead from the battery to
terminal 2 and negative (±) lead to terminal 4, check
that the solenoid operation in the lock (Pull) direction.
(b) Check that there is no continuity between terminals
1 and 3. (d) Reverse the polarity of the voltmeter leads.
(e) Set the door lock manual switch to LOCK, check that
the voltage rises from 0 volts to battery voltage for
approximately 0.2 seconds.
If operation is not as specified, replace the relay.

INSPECTION OF RELAY
INSPECT RELAY VOLTAGE AND CONTINUITY
(a) Disconnect the relay connector and inspect the con-
nector on the wire harness side as shown in the
chart.
Limit Switch
INSPECTION OF SWITCH
INSPECT SWITCH CONTINUITY
(a) Check that there is continuity between terminals 1
and 4 when the switch is ON.
(b) Check that there is no continuity between terminals
1 and 4 when the switch is OFF.
If continuity is not as specified, replace the switch.

INSPECTION OF MIRROR
INSPECT MIRROR OPERATION
(a) Connect the positive (+) lead from the battery to ter-
minal 1 and negative lead to terminal 2, check that
the mirror moves upward.
Then, reverse the polarity, check that the mirror
operation is reversed.
(b) Connect the positive (+) lead from the battery to ter-
minal 2 and negative(±) lead to terminal 3, check that
the mirror moves to the right.
Then, reverse the polarity, check that the mirror
operation is reversed.

INSPECTION OF MOTOR
INSPECT MOTOR OPERATION
(Slide Motor/Operation)
(a) Connect the positive (+) lead from the battery to termi-
nal 1 and the negative (±) lead to terminal 2, check that
the motor turns clockwise (moves to rear side).
(b) Then, reverse the polarity, and check that the motor
turns counterclockwise (moves to front side).
If operation is not as specified, replace the motor.
(Front and Rear Vertical Motor/Operation)
