HOW TO READ CONFIGURATION DIAGRAMS
The wiring harness diagrams clearly show the connector locations and harness routings at each site in actual
vehicles.
Denotes connector No.
The same connector No. is used throughout the circuit diagrams to facilitate connector
location searches.
The first alphabetical symbol indicates the location site of the connector 8nd a number
that follows is the unique number. Numbers are assigned to parts in clockwise oder
on the diagram.
When the conn€ctors are c€ntralized in one place, the connector colors are shovrrn for
easy identification.

position, current flows ttre alternator L terminal to
the field coil and, at the same time, the charge
warning lamp lights up.
is stared and after engine has
started
. When the engine is started, the charge warning
lamp goes out because of the charging voltage
being applied to the alternator L terminal.
. The battery voltage being applied to the alternator
S terminal is monitored by the lC voltage regulator.
Hence, the amount of electricity produced by the
alternator is controlled by allowing and cutting off
the current flowing to the field coil.
. The alternator B terminal supplies power to each
When engine
TROUBLESHOOTING HINTS
1. Charging indicator lamp does not go on when the
ignition switch is turned to "ON", before the
engine starts.
. Check the bulb.
2. Charging indicator lamp fails to go off once the
engine starts.
. Check lC voltage regulator of altemator.
3. Discharged or overcharged battery.
. Check lC voltage regulator of altemator.
4. Charge warning lamp lights up dimly.
. Check combination meter diode (for short).

battery voltage is applied, through the headlamp

When the headlampleveling switch setting is
changed from "0" to "1", the positive (*) input
terminal voltage of the comparator OP AMp 1
(located within the headlampleveling unit) becomes greater than the negative (-) input terminal standard reference voltage value, and Op AMp

2. There is one setting of the headlampleveling

As a result of these HIGH signals, Op AMp 2
outputs LOW signals and OPAMP 3 outputs HIGH
signals to the motor-control lC.
When this happens. the motorcontrol lC is switched ON, current flows to the motor, and the motor
rotates in the forward direction.
The rotation of the mctcr, after passing through
the gears and the output shaft, causes the
headlamp reflectors to move to a downward angle,
thus changing the angle of headlamp illumination.
At this time, the positiondetection sliding resistance is activated in the direction of the low
resistance value, after which the OP AMp 1
negative (-) input terminal voltage value and
positive (*) input terminal voltage value become
equivalent, and OP AMP 2 and OP AMp 3 both
output HIGH signals.
When this happen, the motor-control lC is switched OFF and the motor stops.
NOTE
(1) The same operation occurs if the headlamp
leveling switch is set to another position.
(2) The input open protection circuit functions to stop
the operation of the motor if there is an abnormal
condition, such as damaged or disconnected
wiring within the headlampleveling unit or of the
wiring harness.

TURN-SIGNAL LAMP AND HAZARD LAMP (See
OPERANON
(Turn-signal lamps)
1. When operation is normal
. When the ignition switch is switched to the
"ON" position, battery voltage is applied (via
the hazard switch)to the turn-signaland hazard
flasher unit.
the turn-signal switch is switched to the
' When
"LH" (or "RH") position, Trl (within the flasher
unit) is switched ON and the relay contact (also
.
.
.
2.
@
within the flasher unit) is switched ON; As a
result, the "LH" (or "RH") turn-signal lamps
and turn-signal indicator lamp illuminate.
At the same time, charging to the capacitor (via
R2) begins. and charging continues until the
lower{imit potential (set by COM 3) is reachecJ.
lVjr"n the'capacitor becomes fufly charged. the
COM3 output reverses and Tr1 is switched
OFF; the relay contact is also switched OFF,
and as a result, the "LH" (or "RH,,) turn_signal
lamps and turn-signal indicator lamp are suritch-
ed
OFF.
At the same tirne that Tr1 is switched OFF, the
capacitor begins discharging, and when discharging finishes, the output of COM3 once
again reverses and Tr1 is switched ON, after
which the "LH" (or "RH")turn-signal lamps and
tum-signal indicator lamp illuminate.
. As a result of the continued repetition of the
steps described above, the ,,LH', (or ,,RH,')
turn-signal lamp and turn-signal indicator lamp
flash ON and OFF repeatedly.
lf one iamp wiring is damaged or disconnected
. lf the bulb for one turn-signal tamp is damaged
or disconnected, the result is an overall increase of the resistance for the entire lamp
circuitry. resulting is a decrease of the vcltage
at the R1 part within the flasher unit.
. As a result of this being
detected, the lower_
limit potential set by COM3 is increased, with
the result that the time required for charging of
the capacitor becomes shorter.
. As a result, the ON and OFF cycles of Tr1 also
become shorter, and thus the number of
flashes of the lamps becomes greater.

OPERATION
(Fuel gauge)
.
.
.
When the ignition key is at the "ON" position, the
fuel gauge is activated.
When there is much fuel, the unit's resistance is
small and the current flowing in the circuit is great,
so the gauge's indicator indicates in the "F" area.
When there is little fuel. the unit's resistance is
high and the current flowing in the circuit is small,
so the gauge's indicator indicates in the "E" area.
Remark
Since the fuel gauge is a needle holding type. the
reading of the needle will be kept as it is even if the
.
ignition switch is turned off.
(Engine coolant temperature gauge)
.
.
When the ignition key is at rhe "Ofrl" position, the
engine coolant temperature gauge is activated.
\l/hen the engine coolant temperature is high. the
unit's i'esistance is low and there is a great flow of
current in the circuit. sa the gaugö's indicator
indicates in the "H" area.
. \A/hen the engine coolant
temperature is low, the
unit's resistance is high and there is a smallflow of
current in the circuit, so the gauge's indicator
indicates in the "C" area.
(Reed switch)
.
TROUBLESHOOTING HINTS
1. The fuel gauges doesn't function. or shows the
incorrect indication.
1) Disconnect the connector of the fuel gauge
unit; the "F" side is indicated when terminaf 3
(2WD) or 2 (4WD) is then earthed.
'
. Check the fuel gauge.
2. The engine coolant temperature gauge doesn,t
function, or shows the incorrect indicätion.
1) The "H" side is indicated when the connector
of the engine coolant temperature gauge unit is
disconnected and then earthed.
. check the engine coolant temperature
gauge unit.
3. The oil pressure gauge doesn't function, or shows
the incorrect indication.
1) The "H" side is indicated when tl
of the oit pressure sause unit is Ji,.:"#".1"JO
and then earthed.
. Check the oil pressure gauge unit.
4. Systems dependent upon control aöcording to the
vehicle speed cio not function correctly.
. Check the reed switch (located within the
speedometer).
5. The meter illumination lamp does not illuminate.
1) The tail lamp illuminate.
. Check the rheostat.
Pulses are producted in accordance with the
vehicle speed, and vehicle.speed signals are input
to systems that regulate according to the vehicle
speeo.
(Oil Pressure Gauge)
.
When the ignition switch is at the "ON" position,
the oil pressure gauge is
activateC.
When oil pressure is high, the internal contacis of
the gauge unit are kept closed for a longer period
of time. This causes more current to flow in the
circuit, and the gauge pcinter swings to the high
pressure side.
When oil pressure is low, the internal contacts of
the gauge unit open in a shorter period of time.
Therefore, there is less cunent flowing in the
circuit and the gauge pointer swings to the low
pressure side.

lamp lights up to warn the driver that the amount
of fuel still available for use is small.
(Engine coolant level warning lamp)
n When the coolant level inside the condenser tank
drops below a predetermined level with the
ignition switch in the "ON" position, the engine
coolant level sensor turns "ON' and the engine
coolant warning lamp illuminates to warn the
driver that the level of coolant remaining is low.

Heater/Air Conditioner
HEATER (See P. 4-57.1
OPERATION
.
When the ignition switch is turned ON. the blower
relay is energized. lf the blower switch is turned
ON (t-O. ML, MH, or Hl position) in this condition,
the blower is activated through the circuit via
resistor at a speed corresponding to the blower
switch position.
TROUBLESHOOTING HINTS
1. Blower motor is energized at one switch position
and not energized at another.
. Check harness and connectors between defec_
tive switch position and resistor (or blower
motor in Hl position).
2. Blower motor is energized only when switch is
positioned is Hl.
. Check resistor.
3. Blower motor speed does not represent the switch
position.
. Check blower switch.
AIR CONDITIONER (See P. 4-s9.1
OPERATION
(Gondenser fan and radiator fan controt)
. For the operation of each fan, see COOLING
SYSTEM IP. 4-23.)
(Compressor control)
. Vy'hen 'rhe air conditioner switch is in the ECONO
cr AIC position, if ihe rernperature around the air
thermo sensoi' [temperarure of the evaporator
(cooling unit) intake/exhaust airl is 4'C (39'F) or
higher, and the temperature around the air inlet
sensoi' (tenrperature of aii- flowing through the
evaporator) at the same time is 4"C (39'F) or
higher, output voltage flows from terminal No. 1 of
the air conditioner control unit.
. The engine coolant temperature switch detects
the engine coolant temDeratuie, and if it is 11S"C
(239"F) or higher, the switcn turns "OFF". lf there
is abnormal refrigerant pressure, the dual pressure
switclr turns "OFF" to protect the compressor
circuit.
'
@
lf the engine coolant temperature switch and the
dual pressure switch are both "ON" and the
ignition switch is also "ON", the output voltage
flonring fr,cm ternrinal No. 1 of the air conditionlr
control unit causes the magnetic clutch relay to
turn "ON".
