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.
1. Position the tester so that its converging lens faces the
high-beam lamp ( marked) center to center at a distance
of 3 m from each other.
2. Aim the headlamps to appropriate standard values using
the aiming adjustment screw.

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.

TROUBLESHOOTING
TROUBLESHOOTING PROCEDURES
1. Check air ducts, control rods, etc. for improper connection.
2. Check that the electrical connectors of the relevant components are connected securely and the
fuse is not blown.
3. Perform the troubleshooting as follows; first understand the items to be inspected and the the procedures
comprehensively using Trouble Symptom/Failed Component Cross-Reference Table and then inspect
the appropriate items sequentially.
4. Be sure to perform each component check after disconnecting the relevant connector.

HEATER AND MANUAL AIR CONDITIONER – On-vehicle Service55-12
Caution
(1) To connect the quick joint, press section “A” firmly
against the service valve until a click is heard.
(2) When connecting, run your hand along the hose
while pressing to ensure that there are no bends
in the hose.
5. Start the engine.
6. Set the blower switch to HI (Fast) position
7. Set the A/C switch to ON position
8. Set the temperature control to Max. cooling position
9. Set the mode selection to Face position
10. Set the air selection to Recirculation position
11. Fix engine speed to 1,500 r/min.
12. Check that the high-pressure side pressure is 1,667 –
1,765 kPa.
NOTE
If the pressure is not within this range, adjust it as follows;
cool down the condenser using a cooling fan if the
pressure is higher, and cover the condenser to protect
it from ventilation air if it is lower.
13. Set a dry-bulb/wet-bulb thermometer at the air inlet, and
set a dry-bulb thermometer at the air outlet.
Caution
(1) Set the dry-bulb thermometer at a position where
the temperature sensing section can be directly
blown with cooled air.
(2) Place the dry-bulb/wet-bulb thermometer at a
position where it is not exposed to cooled air
blown out.
14. After the temperature of the air blown out from the air
outlet has been stabilized (10 – 15 minutes after starting),
read the dry-bulb thermometer set at the air outlet and
the wet-valve thermometer set at the air inlet.
15. The air conditioning system is considered in good
condition if the intersecting point of the measurements
obtained in Step (14) is below the performance evaluation
reference line on the graph.
Caution
Do not remove the quick joint immediately after the
performance test has been completed. Stop the engine
and wait until the high-pressure side pressure of the
gauge manifold has been lowered sufficiently.

AIR CONDITIONER55-21
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
