18. INSPECT WASHER FLUID LEVEL WARNING SWITCH
(a) Check that no continuity exists between terminals with the
switch OFF (float up).
(b) Check that continuity exists between terminals with the
switch ON (float down).
If operation is not as specified, replace the switch.
19. INSPECT OPEN DOOR WARNING LIGHT
Disconnect the connector from the door courtesy switch and
ground terminal 1 on the wire harness side, and check that the
warning light lights up.
If the warning light does not light up, inspect the bulb or wire har-
ness.
20. INSPECT SEAT BELT WARNING LIGHT
(a) Remove the integration relay from the instrument panel
junction block.
(b) Ground terminal 2 on the integration relay with the con-
nectors still connected.
(c) Turn the ignition switch ON and check that the warning
light lights up.
If the warning light does not light up, inspect the bulb or wire har-
ness.
21. w/o Power seat:
INSPECT BUCKLE SWITCH CONTINUITY
(a) Check that continuity exists between the terminals on the
switch side connector with the switch ON (belt fastened).
(b) Check that no continuity exists between the terminals on
the switch side connector with the switch OFF (belt unfas-
tened).
If operation is not as specified, replace the seat belt inner belt.
22. w/ Power seat:
INSPECT BUCKLE SWITCH CONTINUITY
(a) Check that continuity exists between terminals 1 and 2 on
the switch side connector with the switch ON (belt fas-
tened).
(b) Check that no continuity exists between terminals 1 and
2 on the switch side connector with the switch OFF (belt
unfastened).
If operation is not as specified, replace the seat belt inner belt.

INSPECT MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and the negative (±) lead to terminal 2, and check that
the motor turns clockwise.
(b) Reverse the polarity, and check that the motor turns coun-
terclockwise.
If operation is not as specified, replace the motor.

13. Rear Door:
INSPECT POWER WINDOW MOTOR PTC THERM-
ISTOR OPERATION
(a) Disconnect the connector from the power window switch.
(b) Connect the positive (+) lead from the ammeter to termi-
nal 1 on the wire harness side connector and the negative
(±) lead to negative terminal of the battery.
(c) Connect the positive (+) lead from the battery to terminal
2 on the wire harness side connector, and raise the win-
dow to the fully position.
(d) Continue to apply voltage and check that the current
changes to less than 1 A within 4 to 90 seconds.
(e) Disconnect the leads from the terminals.
(f) Approximately 60 seconds later, connect the positive (+)
lead from the battery to terminal 2 and the negative (±)
