9. INSPECT REAR WIPER MOTOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
4 and the negative (−) lead to the motor body, check that
the motor operates.
If operation is not as specified, replace the motor.
(b) Operate the motor and stop the motor operation any-
where except at the stop position by disconnecting the
positive (+) lead from terminal 4.
(c) Connect terminals 2 and 4.
(d) Connect the positive (+) lead from the battery to terminal
1 and the negative (−) lead to the motor body, check that
the motor stops running at the stop position after the mo-
tor operates again.
If operation is not as specified, replace the motor.
10. INSPECT WASHER MOTOR OPERATION
Connect the positive (+) lead from the battery to terminal 2 and
the negative (−) lead to terminal 1, check that the motor oper-
ates.
NOTICE:
These tests must be performed quickly (within 20 seconds)
to prevent the coil from burning out.
If operation is not as specified, replace the motor.

METER, ANALOG
Current flow activates a magnetic
coil which causes a needle to
move, thereby providing a relative
display against a background
calibration. LED (LIGHT EMITTING DIODE)
Upon current flow, these diodes
emit light without producing the
heat of a comparable light. IGNITION COIL
Convert low-voltage DC current
into high-voltage ingition current
for firing the spark plugs. 1. SINGLE
FILAMENT
GROUND
The point at which wiring attaches
to the Body, thereby providing a
return path for an electrical circuit;
without a ground, current cannot
flow.
Current flow causes a headlight
filament to heat up and emit light.
A headlight may have either a
single (1) filament or a double (2)
filament. BATTERY
Stores chemical energy and
converts it into electrical energy.
Provides DC current for the auto's
various electrical circuits.
CAPACITOR (Condenser)
A small holding unit for temporary
storage of electrical voltage.
CIRCUIT BREAKER
Basically a reusable fuse, a circuit
breaker will heat and open if too
much current flows through it. Some
units automatically reset when cool,
others must be manually reset.
DIODE
A semiconductor which allows
current flow in only one direction.
DIODE, ZENER
A diode which allows current flow
in one direction but blocks reverse
flow only up to a specific voltage.
Above that potential, it passes the
excess voltage. This acts as a
simple voltage regulator.
PHOTODIODE
The photodiode is a semiconductor
which controls the current flow
according to the amount of light.
FUSE
A thin metal strip which burns
through when too much current
flows through it, thereby stopping
current flow and protecting a
circuit from damage.
FUSIBLE LINK
A heavy-gauge wire placed in
high amperage circuits which
burns through on overloads,
thereby protecting the circuit.
The numbers indicate the cross-
section surface area of the wires.HORN
An electric device which sounds a
loud audible signal.
LIGHT
Current flow through a filament
causes the filament to heat up
and emit light.
METER, DIGITAL
Current flow activates one or
many LED's, LCD's, or fluorescent
displays, which provide a relative
or digital display.
MOTOR
A power unit which converts
electrical energy into mechanical
energy, especially rotary motion. CIGARETTE LIGHTER
An electric resistance heating
element.
DISTRIBUTOR, IIA
Channels high-voltage current
from the ignition coil to the
individual spark plugs.2. DOUBLE
FILAMENT HEADLIGHTS
FUEL
(for High Current Fuse or
Fusible Link.)
(for Medium Current Fuse)

WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS TO TERMINAL 2 OF THE REAR WASHER MOTOR, TERMINAL 3 OF THE
REAR WIPER RELAY AND TERMINAL 1 OF THE REAR WIPER MOTOR THROUGH THE WIPER FUSE.
1. REAR WIPER NORMAL OPERATION
WITH THE IGNITION SW TURNED ON AND REAR WIPER AND WASHER SW TURNED ON, THE CURRENT FLOWING TO TERMINAL 3
OF THE REAR WIPER RELAY FLOWS TO TERMINAL 6 OF THE RELAY "TERMINAL 10 OF THE REAR WIPER AND WASHER SW "
TERMINAL 2 "TOGROUND. THUS, THE RELAY COIL IS ACTIVATED AND THE CURRENT TO TERMINAL 3 OF THE RELAY FLOWS TO
TERMINAL 4 " TERMINAL 4 OF THE REAR WIPER MOTOR " MOTOR "TO GROUND AND CAUSES THE MOTOR TO OPERATE THE
WIPER.
2. REAR WIPER INTERMITTENT OPERATION
WHEN THE IGNITION SW IS ON AND THE REAR WIPER AND WASHER SW IS TURNED TO INT POSITION, CURRENT FLOWING TO
TERMINAL 3 OF THE REAR WIPER RELAY FLOWS TO TERMINAL 2 OF THE RELAY "TERMINAL 13 OF THE REAR WIPER AND
WASHER SW "TERMINAL 2 "GROUND.
THIS CAUSES THE MOTOR TO OPERATE (THE POINT CHANGES) AND THE INTERMITTENT CIRCUIT OF THE RELAY OPERATES.
INTERMITTENT OPERATION OF THE CIRCUIT IS CONTROLLED BY THE CHARGING AND DISCHARGING OF THE CONDENSER
INSTALLED INSIDE THE RELAY.
3. WASHER OPERATION
WITH THE IGNITION SW TURNED ON AND THE REAR WIPER AND WASHER SW TURNED TO ON POSITION, WHEN THE WIPER SW IS
TURNED FURTHER, THE CURRENT FLOWING TO TERMINAL 2 OF THE REAR WASHER MOTOR FLOWS TO TERMINAL 1 OF THE
MOTOR "TERMINAL 12 OF THE REAR WIPER AND WASHER SW "TERMINAL 2 "TO GROUND SO THAT THE WASHER MOTOR
ROTATES AND THE WINDOW WASHER EJECTS THE SPRAY, ONLY WHILE THE SWITCH IS FULLY TURNED.
WHEN THE WIPER SW IS OFF AND THEN TURNED TO WASHER ON (WIPER OFF SIDE), ONLY THE WASHER OPERATES.

THE FAN NO. 2 RELAY (COIL SIDE) "TERMINAL 2 OF THE A/C SINGLE PRESSURE SW "TERMINAL 3 "TERMINAL 2 OF THE A/C
WATER TEMP. SW "TERMINAL 1 "GROUND, AND THE FAN NO. 1 RELAY AND THE FAN NO. 2 RELAY ARE TURNED ON.
AT THE SAME TIME THAT THIS CURRENT FLOWS, CURRENT FROM THE ECU-IG FUSE FLOWS TO THE E/G MAIN RELAY (COIL
SIDE) "GROUND, AND THE E/G MAIN RELAY IS TURNED ON. AS A RESULT, CURRENT FROM THE ALT FUSE FLOWS TO THE CDS
FA N FUSE AND RDI FAN FUSE.
*LOW SPEED OPERATION
WHEN THE IGNITION SW IS TURNED ON AND THE A/C IS ACTIVATED, CURRENT FLOWS FROM THE MG/C RELAY (POINT SIDE) "
THE FAN NO. 3 RELAY (COIL SIDE) "GROUND, AND THE FAN NO. 3 RELAY IS TURNED ON. AS A RESULT, CURRENT FROM THE
CDS FAN FUSE FLOWS TO TERMINAL 2 OF THE A/C CONDENSER FAN MOTOR "TERMINAL 1 "THE FAN NO. 2 RELAY (POINT
SIDE) "THE FAN NO. 3 RELAY (POINT SIDE) "TERMINAL 2 OF THE RADIATOR FAN MOTOR "TERMINAL 1 "GROUND, AND
BOTH OF THE FAN MOTORS, WITH THE RESULT THAT THE FANS ARE ACTIVATED AT LOW SPEED.
IF THE ENGINE COOLANT TEMPERATURE IS APPROX. 90
C (194

15.5 KG/CM
2 (1323 KPA, 191.7 PSI) OR LESS, BOTH THE A/C WATER TEMP. SW AND THE A/C SINGLE PRESSURE SW ARE CLOSED,
SO THAT THE FAN NO. 1 RELAY AND THE FAN NO. 2 RELAY ARE TURNED ON. AS A RESULT, BOTH OF THE FAN MOTOR OPERATE
AT LOW SPEED.
*HIGH SPEED OPERATION
WHEN, DURING A/C OPERATION, THE REFRIGERANT PRESSURE BECOMES HIGHER THAN ORDINARY LEVEL (APPROX. 15.5
KG/CM
2 (1323 PSI. 191.7 KPA)), THE A/C SINGLE PRESSURE SW IS TURNED OFF. AS A RESULT, THE FAN NO. 1 RELAY AND THE
FAN NO. 2 RELAY ARE TURNED OFF, AND THE CURRENT FLOWS FROM THE RDI FAN FUSE TO FAN NO. 1 RELAY (POINT SIDE) "

HEATER BLOWER MOTOR OPERATION
CURRENT IS APPLIED AT ALL TIMES THROUGH THE HTR FUSE TO TERMINAL 5 OF THE HEATER RELAY.
WHEN THE IGNITION SW IS TURNED ON, CURRENT FLOWS THROUGH THE GAUGE FUSE TO TERMINAL 1 OF THE HEATER RELAY
"THE COIL "TERMINAL 3 "TERMINAL 5 OF THE BLOWER SW.
*LOW SPEED OPERATION
WHEN THE BLOWER SW IS MOVED TO LO POSITION, THE CURRENT FLOWS TO TERMINAL 5 OF THE BLOWER SW "TERMINAL 6

TERMINAL 5 OF THE HEATER RELAY "TERMINAL 4 "TERMINAL 1 OF THE BLOWER MOTOR "TERMINAL 2 "TERMINAL 1 OF
THE BLOWER RESISTOR "TERMINAL 4 "GROUND, CAUSING THE BLOWER MOTOR TO ROTATE AT LOW SPEED.
*MEDIUM SPEED OPERATION (OPERATION AT M1, M2)
WHEN THE BLOWER SW IS MOVED TO M1 POSITION, THE CURRENT FLOWING TO TERMINAL 5 OF THE BLOWER SW "
