25. INSPECT ENGINE OIL LEVEL WARNING CIRCUIT
Disconnect the switch connector and inspect the connector on
wire harness side, as shown.
Tester connectionConditionSpecified condition
2 − GroundConstantContinuity
If continuity is not as specified, inspect the wire harness or
ground point.
26. INSPECT ENGINE OIL LEVEL WARNING LIGHT
(a) Disconnect the connector from the switch.
(b) Ground terminal 1 on the wire harness connector.
(c) Turn the ignition switch ON, and check that the warning
light lights up approximately 40 seconds later.
If the warning light does not light up, inspect bulb or wire har-
ness.
27. INSPECT LIGHT CONTROL RHEOSTAT
(a) Connect terminals 1 and 3 through a 3.4 W test bulb.
(b) Connect the positive (+) lead from the battery to terminal
1 and the negative ( −) lead to terminal 2.
(c) Turn the rheostat knob to fully counterclockwise, and
check that the test bulb goes out.
(d) Gradually turn the rheostat knob to clockwise, and check
that the test bulb brightness changes from dark to bright.
If operation is not as specified, replace the rheostat.
HINT:
Adjust the brightness of illumination lights by rheostat.

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.

(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.
4. 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
or equivalent).
(d) Using a fine tip brush, apply a small amount to the wire.
(e) After a few minutes, remove the masking tape.
(f) Do not repair the defogger wire for at least 24 hours.

2. INSPECT POWER WINDOW MASTER SWITCH ILLU-
MINATION
(a) Set the window lock switch to the unlock position.
(b) Connect the positive (+) lead from the battery to terminal 7 and the negative ( −) lead to terminal 1, and check that
all the illuminations light up.
(c) Set the window lock switch to the lock position, and check that all the passenger’s power window switch illumina-
tions go out.
If operation is not as specified, replace the master switch.
3. Using an ammeter: INSPECT ONE TOUCH POWER WINDOW SYSTEM
(a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the ammeter to termi- nal 6 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 13 on the wire harness side connector.
(d) As the window goes down, check that the current flow is up to approximately 7 A.
(e) Check that the current increases approximately 14.5 A or more when the window stops going down.
HINT:
The circuit breaker opens some 4 − 40 seconds after the win-
dow stops going down, so that check must be made before the
circuit breaker operates.
If the operation is as specified, replace the master switch.

4. Using an ammeter with a current − measuring probe:
INSPECT ONE TOUCH POWER WINDOW SYSTEM
(a) Remove the master switch with connector connected.
(b) Attach a current−measuring probe to terminal 6 of the
wire harness.
(c) Turn the ignition switch ON, and set the power window switch in the down position.
(d) As the window goes down, check that the current flow is up to approximately 7 A.
(e) Check that the current increases approximately 14.5 A or more when the window stops going down.
HINT:
The circuit breaker opens some 4 − 40 seconds after the win-
dow stops going down, so check must be made before the cir-
cuit breaker operates.
If operation is as specified, replace the master switch.
