1. DESCRIPTION AND OPERATION OF ENGINE
ELECTRICAL SYSTEM
1) BATTERY
The sealed battery is standard on all cars. There are no vent plugs in the cover. The battery is
completely sealed, except for two small vent holes in the sides.
These vent holes allow the small amount of gas pro-duced in the battery to escape. The battery
has the following advantages over conventional batteries:
No water addition for the life of the battery.
Overcharge protection. If too much voltage is applied to the battery, it will not accept as
much current as a conventional battery. In a conventional battery, the excess voltage will
still try to charge the battery, leading to gassing, which causes liquid loss.
Not as liable to self-discharge as a conventional battery. This is particularly important when
a battery is left standing for long periods of time.
More power available in a lighter, smaller case. -

The battery has three major functions in the electrical system. First, the battery provides a
source of energy for cranking the engine. Second, the battery acts as a voltage stabilizer for the
electrical system. Finally, the battery can, for a limited time, provide energy when the electrical
demand exceeds the output of the alternator.
2) RATINGS
A battery has two ratings: (1) a reserve capacity rating designated at 27°C (80°F), which
is the time a fully charged battery will provide 25 amperes of current flow at or above 10.5 volts;
(2) a cold cranking amp rating determined under testing at -18°C (0°F), which indicates
the cranking
load capacity.
▶Reserve Capacity
The reserve capacity (RC) is the maximum length of time it is possible to travel at night with the
minimum electrical load and no alternator output. Expressed in minutes, the RC rating is the
time required for a fully charged battery, at a temperature of 27 °C (80 °F) and being
discharged at
a current of 25 amperes, to reach a terminal voltage of 10.5 volts.
▶Cold Cranking Amperage
The cold cranking amperage test is expressed at a battery temperature of -18°C (0°F).
The current rating is the minimum amperage, which must be maintained by the battery for 30
seconds at the specified temperature, while meeting a minimum voltage requirement of 7.2
volts. This
rating is a measure of cold cranking capacity.
The battery is not designed to last indefinitely. However, with proper care, the battery will
provide many years of service. If the battery tests well, but fails to perform satisfactorily
in service for no apparent reason, the following factors may point to the cause of the trouble:

CLUTCH
1. OVERVIEW
1) Driving Elements
The driving elements consist of two flat surfaces machined to a smooth finish.
One of these is the rear face of the engine flywheel and the other is the clutch cover pressure
plate. The clutch pressure plate is fitted into a clutch steel cover, which is bolted to the flywheel.
2) Driven Elements
The driven element is the clutch disc with a splined hub which is free to slide lengthwise along
the splines of the input shaft. The driving and driven elements are held in contact by spring
pressure. This pressure is exerted by a diaphragm spring in the clutch cover pressure plate
assembly.
3) Operating Elements
The clutch control system consists of the clutch pedal, clutch master cylinder, concentric slave
cylinder. This system directly releases the clutch by using hydraulic pressure while the
conventional clutch system releases the clutch by using release lever and release fork. This
system provides higher efficiency than conventional clutch system, and its durability is superior.

3310-01PROPELLER SHAFT
1. PROPELLER SHAFT GENERAL INFORMATION
The propeller shaft transfers the power through
the transmission and transfer case to the
front/rear axle differential carrier (final reduction
gear). It is manufactured by a thin rounded steel
pipe to have the strong resisting force against
the torsion and bending. Both ends of propelle
r
shaft are connected to the spider and the cente
r
of propeller shaft is connected to the spline to
accommodate the changes of the height and
length. The rubber bushing that covers the
intermediate bearing keeps the balance of rea
r
propeller shaft and absorbs its vibration.

RAIN SENSOR

4. FUNCTIONS OF RAIN SENSOR
1) Windshield Glass and Coupler Attachment
Check the outer windshield surface of sensing area for wear, damage and scratch. The sensor
is able to compensate the wear up to a specific level. Check the coupler attached surface of
windshield for porosity. If the porosity exists, the sensor cannot function properly.
2) Recognition of AUTO Mode
3) Instant Wipe Function
When the variable resistance knob on the multifunction wiper switch is turned by each 1 stage
from low sensitivity (Smark) to high sensitivity (F mark), the wiper operates one cycle.
And, the wiper also operates during raining up to 5 minutes after rain stops.When the engine is started with the wiper switch “AUTO” position, the wiper operates
one cycle to remind a driver that the wiper switch is in “AUTO” position.
When the wiper switch is turned to “AUTO” from OFF, the wiper operates one cycle. It
always operates one cycle for the initial operation, however, the wiper does not operate
afterwards to prevent the wiper blade wear if not raining when turning the wiper switch to
“AUTO” from “OFF”. However, the wiper operates up to 5 minutes after rain stops.
If this function does not occur, check No. 2 terminal on the rain sensor. If any defective
cannot be found, check the wiper relay (LOW) for defective. 1)
2)
3)If the installed wiper brushes are out of specification (size and length), the rain sensing
area cannot be fully wiped. In this case, the rain sensor’s sensitivity could be
decreased and the wipers are not properly operated -
As described, the STICS recognizes the wiper switch “AUTO” position. If there are not
any problem, go to diagnosis mode in STICS and check the terminal that receives signal
from wiper and communication lines between rain sensor unit and STICS. -
