(AIR BAG) SYSTEM
DIAGNOSIS
 When troubleshooting air bag system, be sure to follow
“DIAGNOSIS” in SECTION 10B. Bypassing these proce-
dures may result in extended diagnostic time, incorrect diag-
nosis, 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 fol-
low proper procedures could result in possible air bag
system activation, personal injury, damage to parts or
air bag system being unable to activate when neces-
sary.
 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.

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-6 GENERAL INFORMATION
 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 temporarily disable air bag system referring to “DISABLING
AIR BAG SYSTEM” in Section 10B.
 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 fol-
low the instructions.
 After 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 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.
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, 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 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 unexpect-
edly during driving, obstructing your view and resulting in an accident.

GENERAL INFORMATION 0A-9
 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.
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.)
PRECAUTION FOR INSTALLING MOBILE COMMUNICATION EQUIPMENT
When installing mobile communication equipment such as CB (Citizens-Band)-radio or cellular-tele-
phone, be sure to observe the following precautions.
Failure to follow cautions may adversely affect electronic control system.
 Keep the antenna as far away as possible from the vehicle’s electronic control unit.
 Keep the antenna feeder more than 20 cm (7.9 in) away from electronic control unit and its wire har-
nesses.
 Do not run the antenna feeder parallel with other wire harnesses.
 Confirm that the antenna and feeder are correctly adjusted.

GENERAL INFORMATION 0A-11
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
harness. 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).

0A-12 GENERAL INFORMATION
 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.
 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. If not specified, use a volt-
meter with high impedance (M
Ω/
Ω/Ω/ Ω/V minimum) or a digital
type voltmeter.

GENERAL INFORMATION 0A-13
 When taking measurements at electrical connectors
using a tester probe, be sure to insert the probe (2) 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 at each terminal, 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,
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

0A-14 GENERAL INFORMATION
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 continuity check or voltage check the following proce-
dure, check the wire harness for open circuit and poor con-
nection 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.
1. Check contact tension by inserting and removing just for once.
1. Looseness of crimping
2. Open
3. Thin wire (single strand of wire)
