erates at high speed.
If operation is not as specified, replace the motor.
10. Stopping at Stop Position: INSPECT FRONT WIPER MOTOR OPERATION
(a) Operate the motor at low speed and stop the motor opera-
tion anywhere except at the stop position by disconnect-
ing positive (+) lead from terminal 3.

18. INSPECT BRAKE FLUID LEVEL WARNING SWITCH
(a) Check that there is no continuity between terminals with
the switch OFF (float up).
(b) Check that there is continuity between terminals with the switch ON (float down).
If operation is not as specified, replace the switch.
19. INSPECT OPEN DOOR WARNING LIGHT
(a) Disconnect the connector from the door courtesy switch and ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON, and check that the warning light lights up.
If the warning light does not light up, test the bulb.
20. INSPECT DOOR COURTESY SWITCH
(a) Check that there is continuity between terminal and the
switch body with the switch ON (switch pin re-
leased:opened door).
(b) Check that there is no continuity between terminal and
the switch body with the switch OFF (switch pin pushed
in:closed door).
If operation is not as specified, replace the switch.
21. INSPECT SEAT BELT WARNING LIGHT
(a) Disconnect the connector from the seat belt warning relay.
(b) Ground terminal 9 on the wire harness side connector.
(c) Turn the ignition switch ON, and check that the warning
light lights up.

3. INSPECT DEFOGGER WIRES
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. 5VOkay (No break in wire)
Approx.10V or 0VBroken wire
HINT:
If there is 10 V, the wire is broken between the center of the wire
and 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.
