High Speed Inspection
1. Clamp the wiper motor in a vise.
The moving parts must be clear of the vise.
2. Connect the connector terminals to the battery.
Refer to the illustration.
3. Check the wiper motor high speed operation.


Auto-Stop Inspection
1. Clamp the wiper motor in a vise.
The moving parts must be clear of the vise.
2. Connect the connector terminals to the battery.
Refer to the illustration.
3. Check the wiper motor low speed operation.
4. Disconnect the positive battery terminal.
This will stop the motor.



5. Connect the connector terminals No. 3 and No. 6 with a
lead wire.
Refer to the illustration.
6. Reconnect the positive battery terminal to connecto
r
terminal No. 4.
This will restart the motor.
Refer to the illustration.
7. Check the auto-stop operation.







Washer Motor Inspection

Check level sensor operation
1. Remove the fuel tank unit.
2.
Apply battery voltage between terminal (B) and (C) through
a 1.12 watt bulb. Check that the bulb lights.
Note:
It will take a short time for the bulb light.
3. Submerge the sensor in fuel. Check that the bulb goes out.
If operation is not correct, replace the fuel tank unit.

BRAKE SYSTEM WARNING LIGHT

Vehicle Speed Sensor Inspection
1. Connect the vehicle speed sensor connector 1 E-44to the
battery (+) terminal and 2
E-44 to the (-) terminal.
2. Connect a resistance of 1.3K ohm to 5K ohm (1/4 W o
r
more) between connectors 1 E-44 and 3 E-44


CAUTION:
Be extremely careful not to connect the battery (+)
terminal to the connector 3
E-44.
This may damage the vehicle speed sensor.



3. Rotate the shaft of the vehicle speed sensor slowly and
measure the voltage at the both ends with a digital tester.

The voltage, with one rotation of shaft fluctuates four times in
the following range: 10 to 14V - 2V or less.
