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.

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.

 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.

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.

 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.

Downloaded from www.Manualslib.com manuals search engine 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.
