*: 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

Disconnect the switch connector and inspect the connector on
wire harness side.

1. MULTI INFORMATION DISPLAY ILLUMINATION
Turn the ignition switch to the ON position and illuminate the all
parts of the display by pushing the ºLIGHTº button.
2. PERFORM CIRCLING CALIBRATION
(a) Push the ºMODEº button several times until ºCOM-
PASSºappears and blinks on the calendar display.
(b) Then push the ºRESET/ADJº button. ºCALIBRATEº ap-
pears and blinks together with the compass display.
(c) Drive the vehicle in a circle until the blinking stops.
(d) If there is not enough space to drive in a circle, drive
around the block until the blinking stops.
(e) When the compass and the calendar display return to
normal mode, calibration is complete

5. INSPECT DEFOGGER WIRE
NOTICE:
When cleaning the glass, use a soft, dry cloth, and wipe the
glass in the direction of the wire. Take care not to damage
the wires. Do not use detergents or glass cleaners with
abrasive ingredients. When measuring voltage, wind a
piece of tin foil around the top of the negative probe and
press the foil against the wire with your finger, as shown.
(a) Turn the ignition switch ON.
(b) Turn the defogger switch ON.
(c) Inspect the voltage at the center of each heat wire, as
shown.
VoltageCriteria
Approx. 5 VOkay (No break in wire)
Approx. 10 V or 0 VBroken wire
HINT:
If there is approximately 10 V, the wire is broken between the
center of the wire and the positive (+) end. If there is no voltage,
the wire is broken between the center of the wire and ground.
(d) Place the voltmeter positive (+) lead against the defogger
positive (+) terminal.
(e) Place the voltmeter negative (-) lead with the foil strip
against the heat wire at the positive (+) terminal end and
slide it toward the negative (-) terminal end.
(f) The point where the voltmeter deflects from zero to sever-
al V is the place where the heat wire is broken.
HINT:
If the heat wire is not broken, the voltmeter indicates 0 V at the
positive (+) end of the heat wire but gradually increases to about
12 V as the meter probe is moved to the other end.
6. IF NECESSARY, REPAIR DEFOGGER WIRE
(a) Clean the broken wire tips with a grease, wax and silicone
remover.
(b) Place the masking tape along both sides of the wire to be
repaired.
(c) Thoroughly mix the repair agent (Dupont paste No.
4817).
