3) Automatic stop action test
Connect yellow terminal of motor to positive
@ battery terminal, and put a jumper
between Blue/White (Blue/Black) and Blue
terminals to see if motor output shaft comes
to a halt at a certain, not just any, angular
position. That position corresponds to start-
ing position of the blade. Using jumper,
stop motor a number of times to make sure
that motor stops at the same position each
time.

4) Internal wiper relay test
1. Disconnect wiper & washer switch coupler.
2. Turn wiper switch to “I NT” position.
3. Connect positive battery terminal to
Yellow/White coupler terminal and nega-
tive battery terminal to Black terminal.
If an operating sound is heard, the relay is
at work properly.

21-5. WATER TEMPERATURE METER
AND GAUGE
The water temperature meter is located in the
combination meter and its gauge unit on the
inlet manifold.
The gauge unit shows different resistance values
depending on the coolant temperature. This
causes a current f lowing through the temperature
meter coil to change, controlling the meter
pointer. That is, when the coolant temperature
is raised, the gauge unit resistance is decreased
with more current flowing through the meter
coil, raising the meter pointer upward from the
“C” position.

Disconnect Y/W (Yellow/White) lead wire
going to gauge unit installed to intake mani-
fold.
Use a bulb (12V 3.4W) in position to ground
above wires as illustrated.
Turn main switch ON, Confirm that the bulb
is lighted and meter pointer fluctuates several
seconds thereafter.
If meter is faulty, replace it.

Warm up gauge unit. Thus make sure its resis-
tance is decreased with increase of temperature.
Temperature and resistance relationship can be
plotted in a graph as shown below.
The fuel level meter circuit consists of the fuel
level meter installed inside the combination
meter and the fuel level gauge installed to the
fuel tank.

Current flowing through the meter coil is
changed to control the meter pointer. That is,
when fuel is full, the fuel level gauge unit
resistance is decreased with more current flowing
into the meter coil, causing the meter pointer
to point at the “F” position.

1. Disconnect Y/R (Yellow/Red) lead wire
going to gauge unit.
2. Use a bulb (12V 3.4W) in position to ground
above lead wire as illustrated.

Make sure the bulb is lighted and meter
pointer fluctuates several seconds thereafter.
If meter is faulty, replace it.

21-9. 4 WHEEL DRIVE LAMP21-10. SEAT BELT WARNING LAMP/
BUZZERThe 4 wheel drive lamp circuit consists of the 4
wheel drive indicator lamp switch installed to
the transfer and the lamp inside the combination
meter.
The 4WD switch so operates that it is switched
ON when transfer gear shift control lever is
shifted to “4H” or “4L” position.
The seat belt warning lamp/buzzer circuit is a
system to light and sound the lamp and buzzer
respectively for several seconds, urging the
driver to wear his seat belt. After several seconds
passed, the lamp goes OFF and the buzzer stops
sounding whether the seat belt is worn or not.

21-15. WIRING HARNESS ROUTING
When reinstalling wire harness, be careful for the following.
l When doing wiring harness related work, make always sure to disconnect battery negative cable from
battery.
l Clamp wire harness securely at prescribed positions.
l Try to route wire harness so as to avoid contact with other parts as much as possible. Use special care
not to let it contact sharp edges of body or other parts.
0 Connect connectors securely.
