PRECAUTIONS
PRECAUTIONS FOR VEHICLE EQUIPPED
WITH A SUPPLEMENTAL RESTRAINT
(AIR BAG) SYSTEM
WARNING:
DThe configuration of air bag system parts are as shown in
the figure. When it is necessary to service (remove, rein-
stall and inspect) these parts, be sure to follow proce-
dures described in SECTION 10B. Failure to follow proper
procedures could result in possible air bag system activa-
tion, personal injury, damage to parts or air bag system
being unable to activate when necessary.
DIf the air bag system and another vehicle system both
need repair, SUZUKI recommends that the air bag system
be repaired first, to help avoid unintended air bag system
activation.
DDo 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.
DIf the vehicle will be exposed to temperatures over 93°C
(200°F) (for example, during a paint baking process), re-
move the air bag system components beforehand to avoid
component damage or unintended air bag system activa-
tion.
DIAGNOSIS
DWhen troubleshooting air bag system, be sure to follow
DIAGNOSIS in SECTION 10B. Bypassing these procedures
may result in extended diagnostic time, incorrect diagnosis,
and incorrect parts replacement.
DNever use electrical test equipment other than that specified
in this manual.
WARNING:
Never attempt to measure the resistance of the air bag (in-
flator) modules (driver and passenger). It is very dangerous
as the electric current from the tester may deploy the air
bag.

ALWAYS CARRY AIR BAG (INFLATOR) MODULE
WITH TRIM COVER (AIR BAG OPENING) AWAY
FROM BODY.
ALWAYS PLACE AIR BAG (INFLATOR) MODULE
ON WORKBENCH WITH TRIM COVER (AIR BAG
OPENING) UP, AWAY FROM LOOSE OBJECTS.

0A1-4 GENERAL INFORMATION
SERVICING AND HANDLING
WARNING:
Many of service procedures require disconnection of “AIR
BAG” fuse and all air bag (inflator) module(s) from initiator
circuit to avoid an accidental deployment.
Driver and Passenger Air Bag (Inflator) Modules
DFor 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.
DWhen 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.
DNever 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 10B before disposal.
DThe 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.
DAfter 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 lubri-
cate the bag as it inflates) and by-products of the chemical
reaction. As with many service procedures, gloves and
safety glasses should be worn.

GENERAL INFORMATION 0A1-5
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 rig-
idly attached to the vehicle. All SDM and mounting bracket
fasteners must be carefully torqued to ensure proper opera-
tion 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.
CAUTION:
DEven when the accident was light enough not to cause air
bags to activate, be sure to inspect system parts and other
related parts according to instructions under REPAIR
AND INSPECTION REQUIRED AFTER AN ACCIDENT in
SECTION 10B.
DWhen servicing parts other than air bag system, if shocks
may be applied to air bag system component parts, re-
move those parts beforehand.
DWhen handling the air bag (inflator) modules (driver and
passenger) or SDM, be careful not to drop it or apply an im-
pact to it. If an excessive impact was applied (e.g.,
dropped from a height of 90 cm (3 feet) or more), never at-
tempt disassembly or repair but replace it with a new one.
DWhen grease, cleaning agent, oil, water, etc. has got onto
air bag (inflator) modules (driver and passenger), wipe off
immediately with a dry cloth.
DAir bag wire harness can be identified easily as it is cov-
ered with a yellow protection tube. Be very careful when
handling it.
DWhen an open in air bag wire harness, damaged wire har-
ness, connector or terminal is found, replace wire har-
ness, connectors and terminals as an assembly.
DDo not apply power to the air bag system unless all com-
ponents are connected or a diagnostic flow table requests
it, as this will set a diagnostic trouble code.
DNever use air bag system component parts from another
vehicle.

0A1-6 GENERAL INFORMATION
CAUTION:
DWhen using electric welding, be sure to temporarily dis-
able air bag system. Refer to DISABLING AIR BAG SYS-
TEM under SERVICE PRECAUTIONS in SECTION 10B.
DNever expose air bag system component parts directly to
hot air (drying or baking the vehicle after painting) or
flames.
DWARNING/CAUTION labels are attached on each part of
air bag system components. Be sure to follow the instruc-
tions.
DAfter vehicle is completely repaired, perform AIR BAG
DIAGNOSTIC SYSTEM CHECK in SECTION 10B.

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:
DWhenever raising a vehicle for service, be sure to follow the instructions under VEHICLE LIFTING
POINTS on SECTION 0A.
DWhen 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.
DWhen it is necessary to run the engine indoors, make sure that the exhaust gas is forced outdoors.
DDo 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.
DTo avoid getting burned, keep away from hot metal parts such as the radiator, exhaust manifold, tail-
pipe, muffler, etc.
DNew 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.
DMake sure the bonnet (front hood) 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:
DBefore starting 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.
DWhen performing service to electrical parts that does not re-
quire use of battery power, disconnect the negative cable of
the battery.

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.
DWhen 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.
DWhenever 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.

the correct installation positions so that the hoses can be re-
installed correctly.
DAfter servicing fuel, oil, coolant, vacuum, exhaust or brake
systems, check all lines related to the system for leaks.
DNever disconnect the fuel line between the fuel pump and in-
jector without first releasing the fuel pressure, or fuel can be
sprayed out under pressure.
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 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.

PRECAUTIONS FOR ELECTRICAL CIRCUIT
SERVICE
DWhen disconnecting and connecting coupler, make sure to
turn ignition switch to OFF position, or electronic parts may
get damaged.
DBe 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.
DNever 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.
DNever 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.
DBe sure to use a specified voltmeter/ohmmeter. Otherwise,
accurate measurements may not be obtained or personal in-
jury may result.
DWhen taking measurements at electrical connectors using a
tester probe, be sure to insert the probe from the wire har-
ness side (backside) of the connector.
DWhen connecting meter probe from terminal side of coupler
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.

1. Check for loose connection
2. Sensor
3. ECM
0A1-12 GENERAL INFORMATION
DWhen checking connection of terminals, check its male half
for bend and female half for excessive opening and both for
locking (looseness), corrosion, dust, etc.
DBefore 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.
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.
DLoose connection of connector
DPoor contact of terminal (due to dirt, corrosion or rust on it, poor
contact tension, entry of foreign object etc.)
DWire harness being open
When checking system circuits including an electronic control unit
such as ECM, ABS control module, etc., it is important to perform
careful check, starting with items which are easier to check.
1) Disconnect negative cable at 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.

Check contact tension by
inserting and removing just for
once
1. Looseness of crimping
2. Open
3. Thin wire (single strand of wire)
GENERAL INFORMATION 0A1-13
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
0A1-14 GENERAL INFORMATION
If measurements were taken as shown in the figure and results
were as listed below, it means that the circuit is open between termi-
nals 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
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. 5V
B-1 and body ground: Approx. 5V 2V voltage drop
A-1 and body ground: Approx. 3V
Short circuit check (wire harness to ground)
1) Disconnect negative cable at 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.

1. Check contact tension by inserting and removing just for
once
2. Check each terminal for bend and proper alignment
GENERAL INFORMATION 0A1-15
INTERMITTENT AND POOR CONNECTION
Most intermittent are caused by faulty electrical connections or wir-
ing, although a sticking relay or solenoid can occasionally be at
fault. When checking it for proper connection, perform careful
check of suspect circuits for:
DPoor mating of connector halves, or terminals not fully seated in
the connector body (backed out).
DDirt or corrosion on the terminals. The terminals must be clean
and free of any foreign material which could impede proper termi-
nal contact. However, cleaning the terminal with a sand paper or
the like is prohibited.
DDamaged connector body, exposing the terminals to moisture
and dirt, as well as not maintaining proper terminal orientation
with the component or mating connector.
DImproperly formed or damaged terminals.
Check each connector terminal in problem circuits carefully to en-
sure good contact tension by using the corresponding mating ter-
minal.
If contact tension is not enough, reform it to increase contact ten-
sion or replace.
DPoor terminal-to-wire connection.
Check each wire harness in problem circuits for poor connection
by shaking it by hand lightly. If any abnormal condition is found,
repair or replace.
DWire insulation which is rubbed through, causing an intermittent
short as the bare area touches other wiring or parts of the vehicle.
DWiring broken inside the insulation. This condition could cause
continuity check to show a good circuit, but if only 1 or 2 strands
of a multi-strand-type wire are intact, resistance could be far too
high.
If any abnormality is found, repair or replace.
