ON-VEHICLE SERVICE
HEADLAMP AIMING
Bring the vehicle in the following conditions before aiming
the headlamp.

Check the tires for inflation pressure. Pump them up if
necessary to the labeled pressure level.

Set the vehicle unladen on a level floor.

Place one person (approximately 55 kg) on the driver’s
seat.

Maintain an engine speed of 2,000 r/min to keep the
battery in the charged condition.
1. Position the tester so that its converging lens faces the
fog lamp center to center at a distance of 10 m.
NOTE
Measure the center of the fog lamp as shown.
A: 572.5 mm (from the center of the vehicle body)
B: 360 mm
2. Remove the fog lamp bezel, and using the aiming
adjustment screw, aim the fog lamp to the standard value.
NOTE
The horizontal direction is non-adjustable. If the beam
axis deviation exceeds the standard value, check the
fog lamp to determine if it is installed out of position and
correct if necessary.

PRINTED-HEATER CHECK
1. Run engine at 2,000 r/min. Check heater element with
battery at full.
2. Turn ON rear window defogger switch. Measure heater
element voltage with circuit tester at rear window glass
centre A.
Condition is good if it indicates about 6V.
3. If 12 V is indicated at A, there is a break in the negative
terminals from A.
Move test bar slowly to negative terminal to detect where
voltage changes suddenly (0V).
4. If 0 V is indicated at A, there is a break in the positive
terminals from A. Defect where the voltage changes
suddenly (12 V) in the same method described above.

DUAL PRESSURE SWITCH SIMPLE CHECK
Measure the high-pressure side pressure. If there is a
continuity between the dual pressure switch terminals with
the dual pressure switch in ON condition as shown in the
graph at left, the switch is in good condition. If not, it is faulty.
Replace the switch.

IDLE-UP OPERATION CHECK
1. Before inspection and adjustment, set vehicle in the
pre-inspection condition:
2. Check whether or not the idle speed is the standard value.
Standard value: 700 ± 50 r/min
NOTE
There is no necessity to make an adjustment, because
the idle speed is automatically adjusted by the ISC system.
If, however, there occurs a deviation from the standard
value for some reason, check the fuel control system.
3. When the A/C is running after turning the A/C switch
to ON, check to be sure that the idle speed is at the
standard value.
Standard value: 850 ± 50 r/min

BCASE COVER, EVAPORATOR REMOVAL
The evaporator, which has been installed in a factory, has
no case cover. Follow the steps below to remove that
evaporator.
1. Cut the case along the shown line to remove the cooling
and blower unit.
2. Remove the air thermo sensor from the evaporator, and
then remove the evaporator towards you, being careful
not to damage its core.
INSPECTION
BLOWER MOTOR CHECK
When battery voltage is applied between the terminals, check
that the motor operates. Also, check that there is no abnormal
noise.
RESISTOR CHECK
Use a circuit tester to measure the resistance between the
terminals as indicated below. Check that the measured value
is at the standard value.
Standard value:
Measurement terminalStandard value Ω
Between terminals 3 and 22.81 ± 10%
Between terminals 3 and 41.28 ± 10%
Between terminals 3 and 10.33 ± 10%

INSTALLATION SERVICE POINT
ACOMPRESSOR INSTALLATION
If a new compressor is installed, first adjust the amount of
oil according to the procedures described below, and then
install the compressor.
1. Measure the amount (X m
) of oil within the removed
compressor.
2. Drain (from the new compressor) the amount of oil
calculated according to the following formula, and then
install the new compressor.
New compressor oil amount
120 to 140 m
– X m
= Y m

NOTE
(1)“120 to 140 ml” is the amount of oil filled in a new
compressor.
(2) Y m
indicates the amount of oil in the refrigerant
line, the condenser, the cooling unit etc.
INSPECTION
REFRIGERANT-TEMPERATURE SWITCH SIMPLE
CHECK
When the A/C is off, check that there is continuity between
the refrigerant-temperature switch terminals. If no, replace
the compressor assembly.
COMPRESSOR MAGNETIC CLUTCH OPERATION
INSPECTION
Connect the battery (+) terminal to the compressor side
terminal, and earth the battery (–) terminal to the body of
the compressor. The condition is normal if the sound of the
magnetic clutch (click) can be heard.AView A

REMOVAL
Remove the clamp bolt of the power steering oil cooler pipe.
Remove the fan motor and shroud assembly while pulling
the power steering oil cooler pipe toward you.
BDISCHARGE HOSE / LIQUID PIPE A
DISCONNECTION
Plug the open end of the disconnected hose and the opening
in the cooling unit not to let foreign matter get into them.
Caution
Seal the hoses completely, otherwise the compressor
oil and receiver will absorb water vapour easily.

Condenser fan does not operate.
Probable cause
If the condenser fan does not turn when the A/C is ON, the cause is probably
a malfunction of the condenser fan motor activation circuit. In this case, reduced
cooling performance will be caused if the vehicle is not running.
