E ADJUSTMENT PROCEDURES
T AIMING
PRE-AIMING INSTRUCTIONS 1. Test dimmer switch operation.
2. Observe operation of high beam indicator light
mounted in instrument cluster.
3. Inspect for badly rusted or faulty headlight assemblies.
These conditions must be corrected before a satisfactory ad-
justment can be made.
4. Place vehicle on a level floor.
5. Jounce front suspension through three (3) oscillations by
applying body weight to hood or bumper.
6. Inspect tire inflation.
7. Rock vehicle sideways to allow vehicle to assume its normal
position.
8. If fuel tank is not full, place a weight in trunk of vehicle to
simulate weight of a full tank [3 kg (6.5 Ibs.) per gallon].
9. There should be no other load in the vehicle other than driver
or substituted weight of approximately 70 kg (150 Ibs.) placed
in driver’s position.
10. Throughly clean headlight lenses.
11. Adjust headlights by following the instructions for the
headlight tester manufacturer.
LUMINOUS INTENSITY MEASUREMENT Measure the luminous intensity of headlights with a photometer in
accordance with the instruction manual prepared by the manufac-
turer of the photometer and make sure that the luminous intensity
is within the following limit.
Luminous intensity at the center of high intensity zone for high
beam.
Limit : 20,000 cd or more NOTE
1. When measuring the luminous intensity of headlight, keep the
engine at 2,000 rpm and have the battery charged.
2. If there are specific regulations for luminous intensity of head-
lights in the region where the vehicle is operated, make sure
that the intensity conforms to the requirements of such reg-
ulations.

lr@rt the special tool into the switch and pry the switch to
remove it from the instrument panel.
INSPECTION
DEFOGGER SWITCH
(1) Remove the defogger switch from the instrument panel
and connect an ohmmeter to the switch side connector.
(2) Operate the switch and check the continuity between the
terminals. * : Indicator light
** : Illumination light
NOTE
0-C indicates that there is continuity between the terminals.

SPECIFICATIONS
GENERAL SPECIFICATIONS VEHICLE-SPEED SENSOR (REED-TYPE SWITCH)
The vehicle-speed sensor functions to substitute pulse signals
for the rotations (vehicle speed) of the transmission’s output
gear;/ t i is located within the speedometer.
Pulse signals are generated when the speedometer cable
rotates.
AUTbMATlC FREE-WHEELING HUB INDICATOR
CONTROL UNIT
The control unit is located at the upper part of the right cowl
side.
The control unit is composed of the pulse-detection circuit
(which receives the input signals from the pulse generator),
the vehicle-speed-detection circuit (which receives the input
signals from the vehicle-speed sensor), the lock-discrimination
circuit (which, based on both of these input signals, judges the
condition of the automatic free-wheeling hub ‘and then trans-
mits indicator output signals to the memory circuit), and the
memory circuit (which “memorizes” the indicator output
signals from the lock-discrimination circuti).

valve Manifold Gauge Valves should be closed
when connecting the manifold gauge set to the service port of the
compressor and the discharge hose. The suction gauge valve at the left is opened to provide a passage between
the suction gauge and the center manifold outlet. The discharge gauge valve at the right is opened to provide a
passage between the discharge pressure gauge and the center manifold outlet.
Detailed instructions for proper use of the gauge set manifold are contained in the text covering each test and
service operation employing these gauges.
Suction Gauge; the left side of the manifold set is calibrated to register 0 to-100 kPa (0 to 30 in. of vacuum) and
0 to 1000 kPa (0 to 150 psi). This gauge is connected to the suction port of the compressor.
Discharge Gauge; the right of the manifold set is calibrated to register 0 to 2100 kPa (0 to 300 psi). For all
tests this gauge is connected to the discharge port of the system.
Center Manifold Outlet provides the necessary connection for a long service hose used when discharging the
system, using a vacuum pump to “pull a vacuum” before charging the system, and for connecting the supply of
refrigerant when charging the system

2OW724 N24FEAE The receiver drier assembly consists of; Drier reservoir, Refriger-
ant level sight glass and Fusible plug.
To Test the Receiver Drier (1) Operate the unit and check the piping temperature by
touching the receiver drier outlet and inlet.
(2) If there is a difference in the temperatures, the
received drier is restricted.
Replace the receiver drier.
SIGHT GLASS REFRlGERANT LEVEL TEST The sight glass is a refrigerant level indicator. To check the refrigerant level, clean the sight glass and start the
vehicle engine. Push the air conditioner button to operate the compressor, place the blower switch to high and
move the temperature lever to extreme left.
After operating for a few minutes in this manner, check the sight glass.
(1) If the sight glass is clear, the magnetic clutch is engaged, the compressor discharge line is warm and the
compressor inlet line is cool; the system has a full charge.
(2) If the sight glass is clear, the magnetic clutch is engaged and there is no significant temperature difference
between compressor inlet and discharge lines; the system has lost some refrigerant.
(3) If the sight glass is clear and the magnetic clutch is disengaged; the clutch is faulty or, the system is out of
refrigerant. Perform low pressure switch test to determine condition. Check low pressure switch and clutch coil
for electrical continuity.
