INSPECTION
1) Trouble diagnosis
Symptom
1. Lights will not come on in either left or
right group of light.
2. Hazard light comes on but turn signal
lights will not.
3. No light comes on; or lights light up but
do not flicker.
4. Turn signal lights are satisfactory, but
hazard light will not come on.
5. Flickering freueqncy is erratic, or lights
remain lit.
6. Turning on hazard warning switch lights up
only one group of lights.
2) Turn signal switch
Using circuit tester, check for continuity
between each pair of terminals by referring to
the chart given below and figure at the right
for each position of turn signal switch lever.
Discontinuity means that contact points are
burnt or otherwise defective in the switch.
For example, switch is in sound condition if
continuity is noted between terminals 2 and
3, with lever in right-turn position, and
between terminals 1 and 3, with lever in left-
turn position.
Possible cause
Fusible link is blown off.
Open circuit (due to poor point contact) in turn
signal dimmer switch.
Defective relay unit.
Open circuit in hazard warning switch.
Light bulbs are defective or improperly grounded.
Defective contact in dimmer switch.

3) Hazard warning switch
Disconnect, lead wire of the hazard warning switch at its coupler. Set switch to ON position and check
for continuity with circuit tester between each of the following pairs of terminals; 2 and 3, 1 and 3, 5
and 6 among those shown in Fig. 21-10. The switch is in sound condition if continuity is noted between
each pair.

21-4. WINDSHIELD WIPER MOTOR
CIRCUIT DESCRIPTION
The circuit is designed so that, when the Wiper Switch is turned “OFF”,the blade will automatically return
to the horizontal position. In Fig. 21-11, when the Wiper Switch is turned “ON” while the Main Switch is
“ON”, current is supplied to the Wiper Motor from the Battery, the motor rotates and the blade moves.
The gear mechanism which converts rotational movement of the motor into swinging movement of the
blade has a cam on the final gear shaft. The cam switches the contacts of P0 and P2 every revolution.
(At the blade stop position, the contact is switched from P2 to P1.)
Repeated contact making and breaking is independent of the wiper motor rotation. When the Wiper Switch
is turned “OFF” while the blade is in a position other than the rest position, motor current path is changed
(i.e. BI/W + BI + MOTOR). Therefore, the motor keeps rotating even though the wiper switch is turned
“OFF”, and the blade will return to the rest position.
When the blade returns to the rest position, the cam contact is changed from P2 to P1 and motor current
is shunted. When supply to the motor is cut off, a counter electromotive force is generated in the
armature. As a result of this counter electromotive force, current flows through the motor and shunt
circuit and the motor stops and the wiper blade stays in the specified position.
[INTERVAL WIPER RELAY CIRCUIT (OPTIONAL)]
When the wiper switch is set to the interval position with the ignition switch ON (the condenser is charged
at this time), current from the battery flows through the yellow/blue wire, generates magnetic force in the
coil in the relay and causes the switch in the relay to turn ON. Then current is transmitted in the sequence
of yellow/blue, relay, wiper switch and blue and causes the wiper motor to rotate (meanwhile, the conden-
ser discharges). By the time the wiper motor makes one rotation and the cam in the motor comes to the
automatic stop position P1, the condenser in the relay has finished discharging (no magnetic force in the
coil in the relay). Then the switch in the relay turns OFF and the wiper stops. They remain that way until
the condenser is fully charged. As soon as the condenser begins discharging after being fully charged,
magnetic force generated in the coil in the relay causes the switch to turn ON. As described above, interval
operation of the wiper motor is controlled by charging and discharging of the condenser.

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.

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.

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.

Use ohmmeter to confirm that level gauge unit
changes in resistance with change of the float
position. Float position-to-resistance relation-
ship can be plotted in a graph as shown below.
The brake warning lamp system consists of the
brake fluid level switch installed to the master
cylinder reservoir and the lamp inside the
combination meter.
This circuit includes a parking brake switch
which gives a warning for unreleased parking
brake.

OPERATION
Brake fluid level warning lamp circuit consists of
brake fluid level switch installed in master
cylinder reservoir, brake fluid level warning lamp
in gage cluster and check relay.
Also, this circuit is additionally provided with
parking brake switch which warns that parking
brake is applied.when engine is stopped,
warning lamp comes on, if ignition switch is
turned ON and parking brake is applied.
For bulb check, warning lamp comes on briefly
during engine starting regardless of brake fluid
level position and parking brake operation.
Because point of check relay is closed.
After engine is started, release parking brake.
If lamp gose off, brake fluid level is adequate.
When warning lamp dose not operate, use circuit
diagram as reference to check bulb, wiring, etc.
