INSPECT MIRROR DEFOGGER
(a) Connect the positive (+) lead from the battery to terminal
4 and the negative (±) lead to terminal 6.
(b) Check that the mirror becomes warm.
HINT:
It takes short time for the mirror to become warm.
6. 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. 5VOkay (No break in wire)
Approx.10V or 0VBroken 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.

3. Using an ammeter:
INSPECT ONE±TOUCH POWER WINDOW SYSTEM/
CURRENT OF CIRCUIT
(a) Disconnect the connector from the master switch.
(b) Connect the positive (+) lead from the ammeter to termi-
nal 3 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
6 on the wire harness side connector.
(d) As the window goes down, check that the current flow is
approximately 7 A.
(e) Check that the current increases up to 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 done 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/
CURRENT OF CIRCUIT
(a) Remove the master switch with connector connected.
(b) Attach a current±measuring probe to terminal 8 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
approximately 7 A.
(e) Check that the current increases up to 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 done before the
circuit breaker operates.
If operation is as specified, replace the master switch.
