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.

23. INSPECT INTEGRATION RELAY OF SEAT BELT
WARNING SYSTEM OPERATION
(a) Connect the positive (+) lead from the battery to terminals
1 and 7.
(b) Connect the terminal 7 to terminal 9 through the 3.4±W
test bulb.
(c) Connect the negative (±) lead from the battery to terminal
10.
(d) Check that the bulb lights and the buzzer sounds for 4 ±
8 seconds.
(e) Return to step (a) and operate the chime again.
(f) Connect the negative (±) lead from the battery to terminal
8.
(g) Check that the buzzer stops sounding.
HINT:
Check the buzzer within a period of 4 to 8 seconds.
If operation is not as specified, replace the relay.

(a) Connect the positive (+) lead from the battery to terminal
1 and negative lead (±) to terminal 3.
(b) Connect the positive (+) lead from the voltmeter to termi-
nal 2 and negative lead to terminal 3.
(c) Turn the rheostat knob and check that the voltage
changes.
26. INSPECT BULB CHECK RELAY OPERATION
(a) Connect the positive (+) lead from the battery to terminal
C through a 1.4±W test bulb and the negative (±) lead to
terminal B, check that the test bulb does not light up.
(b) Connect the positive (+) lead from the battery to terminal
A and check that the test bulb lights up.
If operation is not as specified, replace the relay.

INSPECTION
1. INSPECT DEFOGGER SWITCH CONTINUITY
Check that is continuity exists between terminals 2 and 6.
If continuity is not as specified, check the bulb.
2. INSPECT DEFOGGER TIMER OPERATION
(a) Connect the positive (+) lead from the battery to terminal
4 and the negative (±) lead to terminal 3.
(b) Connect the positive (+) lead from the battery to terminal
5 through a 3.4±W tester bulb.
(c) Push the defogger switch ON, check that the indicator
light and test bulb light up for 12 to 18 minutes, then the
indicator light and test bulb light goes out.
If operation is not as specified, replace the switch.
3. INSPECT DEFOGGER TIMER CIRCUIT
Disconnect the connector from the switch and inspect the con-
nector on the wire harness side, as shown in the table.
