0A-8 GENERAL INFORMATION

When removing the battery, be sure to disconnect the nega-
tive cable first and then the positive cable. When reconnect-
ing the battery, connect the positive cable first and then the
negative cable, and replace the terminal cover.

When removing parts that are to be reused, be sure to keep
them arranged in an orderly manner so that they may be rein-
stalled in the proper order and position.

Whenever you use oil seals, gaskets, packing, O-rings, lock-
ing washers, split pins, self-locking nuts, and certain other
parts as specified, be sure to use new ones. Also, before
installing new gaskets, packing, etc., be sure to remove any
residual material from the mating surfaces.

Make sure that all parts used in reassembly are perfectly
clean.

When use of a certain type of lubricant, bond or sealant is
specified, be sure to use the specified type.
ªAº: Sealant 99000-31150

Be sure to use special tools when instructed.

ELECTRICAL CIRCUIT INSPECTION
PROCEDURE
While there are various electrical circuit inspection methods, de-
scribed here is a general method to check its open and short circuit
by using an ohmmeter and a voltmeter.
OPEN CIRCUIT CHECK
Possible causes for the open circuit are as follows. As the cause is
in the connector or terminal in many cases, they need to be checked
particularly carefully.

Loose connection of connector

Poor contact of terminal (due to dirt, corrosion or rust on it, poor
contact tension, entry of foreign object etc.)

Wire harness being open
When checking system circuits including an electronic control unit
such as ECM, TCM, ABS control module, etc., it is important to per-
form careful check, starting with items which are easier to check.
1) Disconnect negative cable from battery.
2) Check each connector at both ends of the circuit being checked
for loose connection. Also check lock condition of connector if
equipped with connector lock.
3) Using a test male terminal, check both terminals of the circuit be-
ing checked for contact tension of its female terminal.
Check each terminal visually for poor contact (possibly caused
by dirt, corrosion, rust entry of foreign object, etc.).
At the same time, check to make sure that each terminal is
locked in the connector fully.
4) Using continuity check or voltage check procedure described in
the following page, check the wire harness for open circuit and
poor connection with its terminals. Locate abnormality, if any.

CHASSIS AND BODY
ITEM 6-1
Clutch
Pedal inspection
Check clutch pedal for height and free travel referring to Section
7C1. Adjust or correct if necessary.
Fluid inspection
1) Check around master cylinder and reservoir for fluid leakage.
If found leaky, correct.
2) Check fluid level.
If fluid level is lower than the minimum level of reservoir, refilling
is necessary. Fill reservoir with specified brake fluid indicated on
clutch reservoir cap.
For the details, refer to On-vehicle service in Section 7C1.
CAUTION:
Since clutch system of this vehicle is factory-filled with
glycol-base brake fluid, do not use or mix different type
of fluid when refilling system; otherwise serious damage
will occur. Do not use old or used brake fluid, or one taken
from unsealed container.
ITEM 6-2
Brake Discs, Pads, Brake Drums and Shoes Inspection
[Brake discs and pads]
1) Remove wheel and caliper but don't disconnect brake hose from
caliper.
2) Check front disc brake pads and discs for excessive wear, dam-
age and deflection. Replace parts as necessary. For details, re-
fer to Section 5B.
Be sure to torque caliper pin bolts to specification.
[Brake drums and shoes]
1) Remove wheel and brake drum.
2) Check rear brake drums and brake linings for excessive wear
and damage, while wheels and drums are removed. At the same
time, check wheel cylinders for leaks. Replace these parts as
necessary.
For details, refer to Section 5C.

FINAL INSPECTION
Seats
Check that seat slides smoothly and locks securely at
any position. Also check that reclining mechanism of
front seat back allows it to be locked at any angle.
Seat Belt
Inspect belt system including webbing, buckles, latch
plates, retractors and anchors for damage or wear.
If ªREPLACE BELTº label on front seat belt is visible,
replace belt.
Check that seat belt is securely locked.
Battery Electrolyte Level Check
Check that the electrolyte level of all battery cells is
between the upper and lower level lines on the case.
If battery is equipped with built-in indicator, check bat-
tery condition by the indicator.
Accelerator Pedal Operation
Check that pedal operates smoothly without getting
caught or interfered by and other part.
Engine Start
Check engine start for readiness.
On automatic transmission vehicles, try to start the
engine in each select lever position. The starting mo-
tor should crank only in ªPº (Park) or ªNº (Neutral).
On manual transmission vehicles, place the shift le-
ver in ªNeutral,º depress clutch pedal fully and try to
start.
Exhaust System Check
Check for leakage, cracks or loose supports.
Clutch (For Manual transmission)
Check for the following:

Clutch is completely released when depressing
clutch pedal.

No slipping clutch occurs when releasing pedal and
accelerating.

Clutch itself is free from any abnormal condition.
Gearshift or Select Lever (Transmission)
Check gear shift or select lever for smooth shifting to
all positions and for good performance of transmis-
sion in any position.
With automatic transmission equipped vehicle, also
check that shift indicator indicates properly according
to which position select lever is shifted to.
With automatic transmission equipped vehicle, make
sure that vehicle is at complete stop when shifting se-
lect lever to ªPº range position and release all brakes.
Brake
[Foot brake]
Check the following:

that brake pedal has proper travel,

that brake works properly,

that it is free from noise,

that braking force is applied equally on all wheels,

and that brake do not drag.
[Parking brake]
Check that lever has proper travel.
WARNING:
With vehicle parked on a fairly steep slope,
make sure nothing is in the way downhill to
avoid any personal injury or property damage.
Be prepared to apply regular brake quickly
even if vehicle should start to move.
Check to ensure that parking brake is fully effective
when the vehicle is stopped on the safe slope and
brake lever is pulled all the way.
WARNING:
When carrying out road tests, select a safe
place where no man or no running vehicle is
seen so as to prevent any accident.
WARNING:
Before performing the following check, be
sure to have enough room around the vehicle.
Then, firmly apply both the parking brake and
the regular brakes. Do not use the accelerator
pedal. If the engine starts, be ready to turn off
the ignition promptly. Take these precautions
because the vehicle could move without warn-
ing and possibly cause personal injury or
property damage.

REFRIGERANT RECOVERY, EVACUATION AND CHARGING
WARNING:

Your eyes should not be exposed to refrigerant (liquid).
Any liquid Refrigerant-134a escaping by accident shows a temperature as low as approx. ± 6C
(42.8F) below freezing point. Should liquid HFC-134a (R-134a) get into your eyes, it may cause a seri-
ous injury. To protect your eyes against such accident, it is necessary to always wear goggles. Should
it occur that HFC-134a (R-134a) strikes your eye(s), consult a doctor immediately.
± DO NOT USE YOUR HAND TO RUB THE AFFECTED EYE(S). INSTEAD, use quantities of fresh cold
water to splash it over the affected area to gradually raise temperature of such area above freezing
point.
± Obtain proper treatment as soon as possible from a doctor or eye specialist.

Should the HFC-134a (R-134a) liquid come into contact with your skin, the affected area should be
treated in the same manner as when skin is frostbitten or frozen.

Refrigerant must not be handled near where welding or steam cleaning is performed.

Refrigerant should be kept at a cold and dark place. It should never be stored where a high tempera-
ture is anticipated, e.g. where exposed to direct sun light, close to fire or inside vehicle (including
trunk room).

Avoid breathing fumes produced when HFC-134a (R-134a) is burned. Such fumes may be hazardous
to health.
