0A-4 GENERAL INFORMATION
HANDLING AND SERVICING
WARNING:
Many of service procedures require disconnection of
“AIR BAG” fuse and air bag (inflator) modules (driver and
passenger) from deployment loop to avoid an accidental
deployment.
Driver and Passenger Air Bag (Inflator) Modules
For handling and storage of a live air bag (inflator) module,
select a place where the ambient temperature below 65C
(150F), without high humidity and away from electric
noise.
When carrying a live air bag (inflator) module, make sure
the bag opening is pointed away from you. In case of an
accidental deployment, the bag will then deploy with mini-
mal chance of injury. Never carry the air bag (inflator)
module by the wires or connector on the underside of the
module. When placing a live air bag (inflator) module on
a bench or other surface, always face the bag up, away
from the surface. As the live passenger air bag (inflator)
module must be placed with its bag (trim cover) facing up,
place it on the workbench with a slit or use the workbench
vise to hold it securely at its lower mounting bracket. This
is necessary so that a free space is provided to allow the
air bag to expand in the unlikely event of accidental de-
ployment. Otherwise, personal injury may result.
Never dispose of live (undeployed) air bag (inflator) mod-
ules (driver and passenger). If disposal is necessary, be
sure to deploy them according to deployment procedures
described in Section 9J before disposal.
The air bag (inflator) module immediately after deploy-
ment is very hot. Wait for at least half an hour to cool it off
before proceeding the work.
After an air bag (inflator) module has been deployed, the
surface of the air bag may contain a powdery residue.
This powder consists primarily of cornstarch (used to lu-
bricate the bag as it inflates) and by-products of the chem-
ical reaction. As with many service procedures, gloves
and safety glasses should be worn.
SDM
During service procedures, be very careful when handling
a Sensing and Diagnostic Module (SDM). Never strike or
jar the SDM. Never power up the air bag system when the
SDM is not rigidly attached to the vehicle. All SDM and
mounting bracket fasteners must be carefully torqued
and the arrow must be pointing toward the front of the ve-
hicle to ensure proper operation of the air bag system. The
SDM could be activated when powered while not rigidly at-
tached to the vehicle which could cause deployment and
result in personal injury.

0A-6 GENERAL INFORMATION
GENERAL PRECAUTIONS
The WARNING and CAUTION below describe some general precautions that you should observe when servicing
a vehicle. These general precautions apply to many of the service procedures described in this manual, and they
will not necessarily be repeated with each procedure to which they apply.
WARNING:
Whenever raising a vehicle for service, be sure to follow the instructions under “VEHICLE LIFTING
POINTS” on SECTION 0A.
When it is necessary to do service work with the engine running, make sure that the parking brake
is set fully and the transmission is in Neutral (for manual transmission vehicles) or Park (for automatic
transmission vehicles). Keep hands, hair, clothing, tools, etc. away from the fan and belts when the
engine is running.
When it is necessary to run the engine indoors, make sure that the exhaust gas is forced outdoors.
Do not perform service work in areas where combustible materials can come in contact with a hot
exhaust system. When working with toxic or flammable materials (such as gasoline and refrigerant),
make sure that the area you work in is well-ventilated.
To avoid getting burned, keep away from hot metal parts such as the radiator, exhaust manifold, tail-
pipe, muffler, etc.
New and used engine oil can be hazardous. Children and pets may be harmed by swallowing new or
used oil. Keep new and used oil and used engine oil filters away from children and pets.
Continuous contact with used engine oil has been found to cause [skin] cancer in laboratory animals.
Brief contact with used oil may irritate skin. To minimize your exposure to used engine oil, wear a
long-sleeve shirt and moisture-proof gloves (such as dish washing gloves) when changing engine
oil. If engine oil contacts your skin, wash thoroughly with soap and water. Launder any clothing or
rags if wet with oil, recycle or properly dispose of used oil and filters.
Make sure the bonnet is fully closed and latched before driving. If it is not, it can fly up unexpectedly
during driving, obstructing your view and resulting in an accident.
CAUTION:
Before staring any service work, cover fenders, seats and
any other parts that are likely to get scratched or stained dur-
ing servicing. Also, be aware that what you wear (e.g. but-
tons) may cause damage to the vehicle’s finish.
When performing service to electrical parts that does not re-
quire use of battery power, disconnect the negative cable of
the battery.
Page 11 of 557
GENERAL INFORMATION 0A-7
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.
“A”: Sealant 99000-31150
Be sure to use special tools when instructed.
Special Tool
(A): 09917-98221
(B): 09916-58210

0A-8 GENERAL INFORMATION
When disconnecting vacuum hoses, attach a tag describing
the correct installation positions so that the hoses can be re-
installed correctly.
After servicing fuel, oil, coolant, vacuum, exhaust or brake
systems, check all lines related to the system for leaks.
For vehicles equipped with fuel injection systems, never dis-
connect the fuel line between the fuel pump and injector
without first releasing the fuel pressure, or fuel can be
sprayed out under pressure.
When performing a work that produces a heat exceeding
80C in the vicinity of the electrical parts, remove the heat
sensitive electrical part(s) beforehand.
Use care not to expose connectors and electrical parts to wa-
ter which will be a cause of a trouble.

GENERAL INFORMATION 0A-9
Always be careful not to handle electrical parts (computer,
relay, etc.) in a rough manner or drop them.
PRECAUTIONS FOR CATALYTIC CONVERTER
For vehicles equipped with a catalytic converter, use only un-
leaded gasoline and be careful not to let a large amount of un-
burned gasoline enter the converter or it can be damaged.
–Conduct a spark jump test only when necessary, make it as
short as possible, and do not open the throttle.
–Conduct engine compression checks within the shortest
possible time.
–Avoid situations which can result in engine misfire (e.g.
starting the engine when the fuel tank is nearly empty.).
PRECAUTIONS FOR ELECTRICAL CIRCUIT
SERVICE
When replacing a fuse, make sure to use a fuse of the speci-
fied capacity. Use of a fuse with a larger capacity will cause
a damage to the electrical parts and a fire.
When disconnecting and connecting coupler, make sure to
turn ignition switch OFF, or electronic parts may get dam-
aged.

0A-10 GENERAL INFORMATION
When disconnecting connectors, never pull the wiring har-
ness. Unlock the connector lock first and then pull them
apart by holding connectors themselves.
When connecting connectors, also hold connectors and put
them together until they lock securely (a click is heard).
When installing the wiring harness, fix it with clamps so that
no slack is left.
When installing vehicle parts, be careful so that the wiring
harness is not interfered with or caught by any other part.
Page 15 of 557
GENERAL INFORMATION 0A-11
Be careful not to touch the electrical terminals of parts which
use microcomputers (e.g. electronic control unit like as
ECM, PCM, P / S controller, etc.). The static electricity from
your body can damage these parts.
Never connect any tester (voltmeter, ohmmeter, or whatever)
to electronic control unit when its coupler is disconnected.
Attempt to do it may cause damage to it.
Never connect an ohmmeter to electronic control unit with
its coupler connected to it. Attempt to do it may cause dam-
age to electronic control unit and sensors.
Be sure to use a specified voltmeter / ohmmeter. Otherwise,
accurate measurements may not be obtained or personal in-
jury may result. If not specified, use a voltmeter with high-im-
pedance (MΩ/ V minimum) or a digital type voltmeter.
When taking measurements at electrical connectors using a
tester probe (2), be sure to insert the probe from the wire har-
ness side (backside) of the connector (1).
When connecting meter probe (2) from terminal side of cou-
pler (1) because it can’t be connected from harness side, use
extra care not to bend male terminal of coupler of force its fe-
male terminal open for connection.
In case of such coupler as shown connect probe as shown
to avoid opening female terminal.
Never connect probe where (3) male terminal is supposed to
fit.
To avoid damage to the harness, protect its part which may
contact against a part forming a sharp angle by winding tape
or the like around it.

0A-12 GENERAL INFORMATION
When checking connection of terminals, check its male half
for bend and female half for excessive opening and both for
locking (looseness), corrosion, dust, etc.
Before measuring voltage to check for electrical system,
check to make sure that battery voltage is 11 V or higher.
Such terminal voltage check at low battery voltage will lead
to erroneous diagnosis.
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.

2. Open
3. Thin wire (single strand of wire)
Check contact tension by
inserting and removing just
for once
GENERAL INFORMATION 0A-13
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.
Continuity Check
1) Measure resistance between connector terminals at both ends
of the circuit being checked (between A-1 and C-1 in the figure).
If no continuity is indicated (infinity or over limit), that means that
the circuit is open between terminals A-1 and C-1.
2) Disconnect the connector included in the circuit (connector-B in
the figure) and measure resistance between terminals A-1 and
B-1.
If no continuity is indicated, that means that the circuit is open
between terminals A-1 and B-1. If continuity is indicated, there
is an open circuit between terminals B-1 and C-1 or an ab-
normality in connector-B.
Voltage Check
If voltage is supplied to the circuit being checked, voltage check can
be used as circuit check.
1) With all connectors connected and voltage applied to the circuit
being checked, measure voltage between each terminal and
body ground.

1. Other parts
1. To other parts
2 V voltage drop
0A-14 GENERAL INFORMATION
If measurements were taken as shown in the figure at the left and
results were as listed below, it means that the circuit is open be-
tween terminals B-1 and A-1.
Voltage Between:
C-1 and body ground: Approx. 5 V
B-1 and body ground: Approx. 5 V
A-1 and body ground: 0 V
Also, if measured values were as listed below, it means that there
is a resistance (abnormality) of such level that corresponds to the
voltage drop in the circuit between terminals A-1 and B-1.
Voltage Between:
C-1 and body ground: Approx. 5 V
B-1 and body ground: Approx. 5 V
A-1 and body ground: Approx. 3 V
SHORT CIRCUIT CHECK (wire harness to ground)
1) Disconnect negative cable from battery.
2) Disconnect connectors at both ends of the circuit to be checked.
NOTE:
If the circuit to be checked is connected to other parts, dis-
connect all connectors of those parts.
Otherwise, diagnosis will be misled.
3) Measure resistance between terminal at one end of circuit (A-1
terminal in figure) and body ground. If continuity is indicated, it
means that there is a short to ground between terminals A-1 and
C-1 of the circuit.
4) Disconnect the connector included in circuit (connector B) and
measure resistance between A-1 and body ground.
If continuity is indicated, it means that the circuit is shorted to the
ground between terminals A-1 and B-1.
