GENERAL INFORMATION 0A-3
Precautions
Precaution for Vehicles Equipped with a Sup-
plemental Restraint (Air Bag) System
Diagnosis
• When troubleshooting air bag system, be sure to follow “Air
Bag Diagnostic System Check” in Section 10B. Bypassing
these procedures may result in extended diagnostic time,
incorrect diagnosis, and incorrect parts replacement.
• Never use electrical test equipment other than that specified
in this manual.
WARNING:
• The configuration of air bag system parts are as shown
in the figure. When it is necessary to service (remove,
reinstall and inspect) these parts, be sure to follow
procedures described in Section 10B. Failure to follow
proper procedures could result in possible air bag sys-
tem activation, personal injury, damage to parts or air
bag system being unable to activate when necessary.
• If the air bag system and another vehicle system both
need repair, SUZUKI recommends that the air bag sys-
tem be repaired first, to help avoid unintended air bag
system activation.
• Do not modify the steering wheel, dashboard, or any
other air bag system components. Modifications can
adversely affect air bag system performance and lead
to injury.
• If the vehicle will be exposed to temperatures over
93°C (200°F) (for example, during a paint baking pro-
cess), remove the air bag system components before-
hand to avoid component damage or unintended air
bag system activation.
1. Air bag wire harness (in instrument panel
wire harness and floor wire harness)
5. Contact coil
2. Passenger air bag (inflator) module 6. Driver air bag (inflator) module
3. SDM 7. Seat belt pretensioner (if equipped)
4. DLC
WARNING:
Never attempt to measure the resistance of the air bag
(inflator) modules (driver and passenger) and seat belt
pretensioners (driver and passenger). It is very danger-
ous as the electric current from the tester may deploy the
air bag or activate the pretensioner.

0A-4 GENERAL INFORMATION
Servicing and handling
WARNING:
Many of service procedures require disconnection of “Air
Bag” fuse and all air bag (inflator) module(s) from initia-
tor circuit 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 65°C (150°F), 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 minimal 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 pas-
senger air bag (inflator) module must be placed with its
bag (trim cover) facing up, place it on the workbench
with a slit (1) or use the workbench vise (2) to hold it
securely at its lower mounting bracket (3). This is nec-
essary so that a free space is provided to allow the air
bag to expand in the unlikely event of accidental
deployment. Otherwise, personal injury may result.
• Never dispose of live (undeployed) air bag (inflator)
modules (driver and passenger). If disposal is neces-
sary, be sure to deploy them according to deployment
procedures described in Section 10B 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 resi-
due. This powder consists primarily of cornstarch
(used to lubricate the bag as it inflates) and by-prod-
ucts of the chemical reaction. As with many service
procedures, gloves and safety glasses should be worn.
[A]: Always Carry Air Bag (Inflator) Module With Trim Cover (Air Bag Opening) Away from
Body.
[B]: Always Place Air Bag (Inflator) Module On Workbench With Trim Cover
(Air Bag Opening) Up, Away From Loose Objects.

GENERAL INFORMATION 0A-5
WARNING:
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 vehicle to ensure proper operation of the air bag system.
The SDM could be activated when powered while not rigidly attached to the vehicle which could
cause deployment and result in personal injury.
WARNING:
Driver and Passenger Seat Belt Pretensioners (If
equipped)
• For handling and storage of a live seat belt preten-
sioner, select a place where the ambient temperature
below 65°C (150°F), without high humidity and away
from electric noise.
• Never carry seat belt pretensioner by wire or connector
of pretensioner. When placing a live seat belt preten-
sioner on the workbench or some place like that, be
sure not to lay it with its exhaust hole (1) provided side
facing down. It is also prohibited to put something on
its face with an exhaust hole (1) or to put a seat belt
pretensioner on top of another. Otherwise, personal
injury may result.
• Never dispose of live (inactivated) seat belt pretension-
ers (driver and passenger). If disposal is necessary, be
sure to activate them according to activation proce-
dures described in Section 10B before disposal.
• The seat belt pretensioner immediately after activation
is very hot. Wait for at least half an hour to cool it off
before proceeding the work.
• With many service procedures, gloves and safety
glasses should be worn to prevent any possible irrita-
tion of the skin or eyes.

0A-6 GENERAL INFORMATION
CAUTION:
• Even when the accident was light enough not to cause air bags to activate, be sure to inspect sys-
tem parts and other related parts according to instructions under “Repair and Inspection Required
after an Accident” in Section 10B.
• When servicing parts other than air bag system, if shocks may be applied to air bag system compo-
nent parts, remove those parts beforehand.
• When handling the air bag (inflator) modules (driver and passenger), seat belt pretensioners (driver
and passenger) or SDM, be careful not to drop it or apply an impact to it. If an excessive impact was
applied (e.g., dropped from a height of 90 cm (3 feet) or more), never attempt disassembly or repair
but replace it with a new one.
• When grease, cleaning agent, oil, water, etc. has got onto air bag (inflator) modules (driver and pas-
senger) or seat belt pretensioners (drive and passenger), wipe off immediately with a dry cloth.
• Air bag wire harness can be identified easily as it is covered with a yellow protection tube. Be very
careful when handling it.
• When an open in air bag wire harness, damaged wire harness, connector or terminal is found,
replace wire harness, connectors and terminals as an assembly.
• Do not apply power to the air bag system unless all components are connected or a diagnostic
chart requests it, as this will set a diagnostic trouble code.
• Never use air bag system component parts from another vehicle.
• When using electric welding, be sure to disconnect air bag (inflator) module connectors (driver and
passenger) and seat belt pretensioner connectors (driver and passenger) respectively.
• Never expose air bag system component parts directly to hot air (drying or baking the vehicle after
painting) or flames.
• WARNING / CAUTION labels are attached on each part of air bag system components. Be sure to
follow the instructions.
• After vehicle is completely repaired, perform “Air Bag Diagnostic System Check” in Section 10B.

GENERAL INFORMATION 0A-7
General Precautions
The WARNING and CAUTION below describe some general precautions that you should observe when servic-
ing 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.
• Before starting any service work, cover fenders, seats
and any other parts that are likely to get scratched or
stained during servicing. Also, be aware that what you
wear (e.g, buttons) may cause damage to the vehicle’s
finish.
• When performing service to electrical parts that does
not require use of battery power, disconnect the nega-
tive cable of the battery.
WARNING:
• Whenever raising a vehicle for service, be sure to follow the instructions under “Vehicle Lifting
Points” in this section.
• 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 auto-
matic 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 refriger-
ant), 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,
tailpipe, 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 ani-
mals. 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.

0A-8 GENERAL INFORMATION
• When removing the battery, be sure to disconnect the
negative cable first and then the positive cable. When
reconnecting 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 reinstalled in the proper order and position.
• Whenever you use oil seals, gaskets, packing, O-rings,
locking washers, split pins, self-locking nuts, and cer-
tain 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

GENERAL INFORMATION 0A-9
• When disconnecting vacuum hoses, attach a tag
describing the correct installation positions so that the
hoses can be reinstalled 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
disconnect 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
80°C (176°F) 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 water which will be a cause of a trouble.
• Always be careful not to handle electrical parts (com-
puter, relay, etc.) in a rough manner or drop them.

0A-10 GENERAL INFORMATION
Precautions For Catalytic Converter
For vehicles equipped with a catalytic converter, use only unleaded gasoline and be careful not to let a
large amount of unburned 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
specified 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
damaged.
• When disconnecting connectors, never pull the wiring
harnesses. Unlock the connector lock first and then pull
them apart by holding connectors themselves.

GENERAL INFORMATION 0A-11
• When connecting connectors, also hold connectors and
push 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 wir-
ing harness is not interfered with or caught by any other
part.
• 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.
• 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 elec-
tricity from your body can damage these parts.

0A-12 GENERAL INFORMATION
• Never connect any tester (voltmeter, ohmmeter, or what-
ever) to electronic control unit when its coupler is dis-
connected. 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 damage to electronic control unit and sensors.
• Be sure to use a specified voltmeter / ohmmeter. Other-
wise, accurate measurements may not be obtained or
personal injury may result.
• When taking measurements at electrical connectors
using a tester probe (2), be sure to insert the probe from
the wire harness side (backside) of the connector (1).
• When connecting meter probe (2) from terminal side of
coupler (1) because it can’t be connected from harness
side, use extra care not to bend male terminal of coupler
of force its female terminal open for connection.
In case of such coupler as shown connect probe as
shown to avoid opening female terminal.
Never connect probe where male terminal is supposed
to fit.
• 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 11V or higher.
Such terminal voltage check at low battery voltage will
lead to erroneous diagnosis.

GENERAL INFORMATION 0A-13
Electrical Circuit Inspection Procedure
While there are various electrical circuit inspection methods,
described 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
perform 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
being 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 the following continuity check or voltage check proce-
dure, check the wire harness for open circuit and poor con-
nection with its terminals. Locate abnormality, if any.
1. Check contact tension by inserting and removing just for once
1. Looseness of crimping
2. Open
3. Thin wire (single strand of wire)

0A-14 GENERAL INFORMATION
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 indi-
cated, there is an open circuit between terminals B-1 and C-
1 or an abnormality 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 cir-
cuit being checked, measure voltage between each terminal
and body ground.
a) If measurements were taken as shown in the figure at the
left and results were as listed below, it means that the cir-
cuit is open between terminals B-1 and A-1.
Voltage Between
C-1 and body ground: Approx. 5V
B-1 and body ground: Approx. 5V
A-1 and body ground: 0V
b) Also, if measured values were as listed below, it means that
there is a resistance (abnormality) of such level that corre-
sponds to the voltage drop in the circuit between terminals
A-1 and B-1.
Voltage Between
C-1 and body ground: Approx. 5V
B-1 and body ground: Approx. 5V
A-1 and body ground: Approx. 3V (2V voltage drop)

GENERAL INFORMATION 0A-15
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.
3) Measure resistance between terminal at one end of circuit
(A-1 terminal in figure) and body ground. If continuity is indi-
cated, it means that there is a short to ground between ter-
minals 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.
Intermittent and Poor Connection
Most intermittent are caused by faulty electrical connections or
wiring, although a sticking relay or solenoid can occasionally be at
fault. When checking it for proper connection, perform careful
check of suspect circuits for:
• Poor mating of connector halves, or terminals not fully
seated in the connector body (backed out).
• Dirt or corrosion on the terminals. The terminals must be
clean and free of any foreign material which could impede
proper terminal contact. However, cleaning the terminal with
a sand paper or the like is prohibited.
• Damaged connector body, exposing the terminals to mois-
ture and dirt, as well as not maintaining proper terminal ori-
entation with the component or mating connector.
NOTE:
If the circuit to be checked is connected to other parts
(1), disconnect all connectors of those parts.
Otherwise, diagnosis will be misled.
1. To other parts
