Servicing and Handling
WARNING!
Many of service procedures require
disconnection of “A/BAG” fuse and all air
bag (inflator) module(s) from initiator circuit
to avoid an accidental deployment.
Driver, Passenger, Side and Curtain 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 passenger 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). It is also
prohibited to place anything on top of the
trim cover and stack air bag (inflator)
modules. This is necessary 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, passenger, side
and curtain). If disposal is necessary, be
sure to deploy them according to
deployment procedures described in “Air
Bag (Inflator) Module and Seat Belt
Pretensioner Disposal in Section 8B”
before disposal.
• The air bag (inflator) module immediately
after deployment 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
lubricate the bag as it inflates) and by-
products 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.

Precautions for Electrical Circuit ServiceS7RS0B0000008
• 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 connecto r lock first and then pull
them apart by holding connectors themselves. • When connecting connectors, also hold connectors
and put them together until th ey 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.
• To avoid damage to the harnes s, protect its part which
may contact against a part forming a sharp angle by
winding tape or the like around it.

• The four cylinders of the engine are identified by numbers; No.1 (1), No.2 (2 ), No.3 (3) and No.4 (4)
counted from crankshaft pulley side to flywheel side.
Engine Diagnosis General DescriptionS7RS0B1101002
NOTE
There are two types of OBD system
depending on the vehicle specification.
For details, refer to “Precaution on On-Board
Diagnostic (OBD) System”.

This vehicle is equipped with an engine and emission
control system which are under control of ECM.
The engine and emission control system in this vehicle
are controlled by ECM. ECM has an On-Board
Diagnostic system which detects a malfunction in this
system and abnormality of those parts that influence the
engine exhaust emission. When diagnosing engine
troubles, be sure to have full understanding of the outline
of “On-Board Diagnostic System Description” and each
item in “Precautions in Diagnosing Trouble” and execute
diagnosis according to “Engine and Emission Control
System Check”.
There is a close relationship between the engine
mechanical, engine cooling system, ignition system,
exhaust system, etc. and the engine and emission
control system in their structure and operation. In case of
an engine trouble, even when the malfunction indicator
lamp (MIL) doesn’t turn ON, it should be diagnosed
according to “Engine and Emission Control System
Check”.
On-Board Diagnostic System DescriptionS7RS0B1101003
NOTE
There are two types of OBD system
depending on the vehicle specification.
For details, refer to “Precaution on On-Board
Diagnostic (OBD) System”.

Euro OBD Model
ECM in this vehicle has the following functions.
• When the ignition switch is turned ON with the engine at a stop, malfunction indicator lamp (MIL) (1) turns
ON to check the circuit of the malfunction indicator
lamp (1). • When ECM detects a malfunction which gives an
adverse effect to vehicle emission while the engine is
running, it makes the malfunction indicator lamp (1) in
the meter cluster of the inst rument panel turn ON or
flash (flashing only when detecting a misfire which
can cause damage to the catalyst) and stores the
malfunction area in its memory.
(If it detects that contin uously 3 driving cycles are
normal after detecting a malfunction, however, it
makes MIL (1) turn OFF although DTC stored in its
memory will remain.)
• As a condition for detecting a malfunction in some areas in the system being monitored by ECM and
turning ON the malfunction indicator lamp (1) due to
that malfunction, 2 driving cycle detection logic is
adopted to prevent erroneous detection.
• When a malfunction is detected, engine and driving conditions then are stored in ECM memory as freeze
frame data. (For the details, refer to description on
“Freeze Frame Data”.)
• It is possible to communicate by using not only SUZUKI scan tool (2) but also OBD generic scan tool.
(Diagnostic information can be accessed by using a
scan tool.)
Warm-Up Cycle
A warm-up cycle means sufficie nt vehicle operation such
that the coolant temperature has risen by at least 22 °C
(40 °F) from engine starting and reaches a minimum
temperature of 70 °C (160 ° F).
