*: There is resistance because this circuit is grounded through
the bulb.
If the circuit is as specified, replace the sensor.
If the circuit is not as specified, inspect the circuits connected
to other parts.
23. INSPECT OPEN DOOR WARNING LIGHT
Disconnect the connector from the door courtesy switch, and
ground terminal 1 on the wire harness side connector and
check that the warning light lights up.
If the warning light does not light up, inspect the bulb or wire har-
ness.
24. INSPECT DOOR COURTESY SWITCH
(See page BE-31)
25. INSPECT SEAT BELT WARNING LIGHT
(a) Disconnect the connector from the terminals buckle
switch and ground terminal on the wire harness side con-
nector as shown in the illustration.
(b) Turn the ignition switch ON and check that the warning
light lights up.
If the warning light does not light up, check the bulb circuit.

26. INSPECT BUCKLE SWITCH CONTINUITY
(a) Check that continuity exists between the terminals on the
switch side connector with the switch ON (belt unfas-
tened).
(b) Check that no continuity exists between the terminals on
the switch side connector with the switch OFF (belt fas-
tened).
27. INSPECT WASHER LEVEL WARNING LIGHT
(a) Disconnect the connectors from the level warning switch.
(b) Connect terminals on the wire harness side connector of
the level warning switch connector.
(c) Turn the ignition switch ON, check that the warning light
come on.
If the warning light does not light up, test the bulb.
28. INSPECT WASHER LEVEL WARING 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.
29. INSPECT WASHER FLUID LEVEL WARNING SWITCH

30. INSPECT LIGHT CONTROL RHEOSTAT OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and the negative lead (-) to terminal 3.
(b) Connect the positive (+) lead from the voltmeter to termi-
nal 2 and the negative lead (-) to terminal 3.
(c) Turn the rheostat knob and check that the voltage
changes.
If operation is not as specified, replace switch.

INSPECT SEAT BELT WARNING OCCUPANT DETEC-
TION SENSOR CONTINUITY
Check that continuity exists between the terminals 1 and 2
when pressing the sensing part (electric resistance <100W).
If continuity is not as specified, replace the sensor.
