ground point.
14. INSPECT OPEN DOOR WARNING LIGHT
(a) Disconnect the connectors from the door courtesy switch
and ground terminal on the wire harness side connector.
(b) Turn the ignition switch ON, check that the warning light
lights up.
If the warning light does not light up, test the bulb.
15. INSPECT OPEN DOOR COURTESY SWITCH

16. INSPECT SEAT BELT WARNING LIGHT
(a) Disconnect the connector from the driver's seat belt re-
tractor assembly.
(b) Connect terminals 1 and 2 on the wire harness side con-
nector.
(c) Turn the ignition switch ON, and check that the warning
light lights up.
If the warning light does not light up, test the bulb.
17. INSPECT SEAT BELT RETRACTOR SWITCH
CONTINUITY
(a) Check that there is continuity between terminals on the
switch side connector with the switch ON (belt down-
ward).
(b) Check that there is continuity between terminals on the

INSPECTION
1. w/ Timer:
INSPECT DEFOGGER SWITCH CONTINUITY
Check that there is continuity between terminals 1 and 3.
If continuity is not as specified, check the bulb.
2. INSPECT DEFOGGER TIMER OPERATION
(a) Connect the positive (+) lead from the battery to terminal
2 and the negative (-) lead to terminal 4.
(b) Connect the positive (+) lead from the battery to terminal
6 through a 3.4 W tester bulb.
(c) Push the defogger switch ON, check that the indicator
light and test bulb light up for 12 to 18 minutes, then the
indicator light and test bulb lights go out.
If operation is not as specified, replace the switch.
3. INSPECT DEFOGGER TIMER CIRCUIT
Disconnect the connector from the switch and inspect the con-
nector on the wire harness side, as shown in the chart.

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. 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.

2. 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
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 made before the
circuit breaker operates.
If the operation is as specified, replace the master switch.
3. 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
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 made before the
circuit breaker operates.
If operation is as specified, replace the master switch.

BATTERY
PRECAUTION
In order to prevent a short circuit while doing work on the electri-
cal circuit such as disconnecting a connector, first turn off the
ignition switch and disconnect the negative (-) terminal cable
from the battery before starting work.
HINT:
When battery voltage is required for operation of a functioning
part, connect the cable to the battery when needed, and
promptly disconnect it when no longer necessary.
CAUTION:

Work must be started after 90 seconds from the time
the ignition switch is turned to the ºLOCKº position
and the negative (-) terminal cable is disconnected
from the battery.

To avoid erasing the memory of each memory sys-
tem, never use a back-up power supply from outside
the vehicle.
