Precautions
Precautions on Service and Diagnosis of Air
Bag System
S7RS0B8200001
WARNING!
• If 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.
• Do not modify the steering wheel, dashboard, both front seat or any other on
or around air bag system components.
Modifications can adversely affect air bag
system performance and lead to injury.
• Be sure to follow the procedures described in this section. Failure to follow
procedures could result in possible air bag
system activation, personal injury or
unneeded air bag system repairs.

• WARNING / CAUTION labels are attached on each
part of air bag system components (SDM, air bag
(inflator) modules and seat belt pretensioners). Be
sure to follow the instructions.
• Many of service procedures require disconnection of
“A/BAG” fuse and air bag (inflator) module(s) (driver,
passenger, side of both si des and curtain of both
sides) from initiator circuit to avoid an accidental
deployment.
• Do not apply power to the air bag system unless all components are connected or a diagnostic flow
requests it, as this will set a DTC.
• The “Air Bag Diagnostic S ystem Check” must be the
starting point of any air bag diagnostics. The “Air Bag
Diagnostic System Check” will verify proper “AIR
BAG” warning right operatio n and will lead you to the
correct flow to diagnose any air bag malfunctions.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacements. • Never use air bag component parts from another
vehicle.
• If the vehicle will be exposed to temperatures over 93
° C (200 °F) (for example, during a paint baking
process), remove the air bag system components
beforehand to avoid component damage or
unintended system activation.
• When handling the air bag (inflator) modules (driver, passenger, side of both si des and curtain of both
sides), seat belt pretensio ners (driver and passenger),
SDM, forward-sensor or side-sensor, be careful not to
drop it or apply an impact to it. If an excessive impact
was applied (e.g., SDM, forward-sensor and side-
sensor are dropped, air bag (inflator) module is
dropped from a height of 90 cm (3 ft) or more, seat
belt pretensioner (retractor assembly) is dropped from
a height of 30 cm (1 ft) or more), never attempt
disassembly or repair but replace it with a new one.
• When using electric welding, be sure to disconnect air bag (inflator) module connectors (driver, passenger,
side of both sides and curtain of both sides) and seat
belt pretensioner connectors (driver and passenger)
respectively.
• When applying paint around the air bag system related parts, use care so that the harness or
connector will not be expo sed to the paint mist.
• Never expose air bag system component parts directly to hot air (drying or baking the vehicle after
painting) or flames.
WARNING!
When performing service on or around air
bag system components or air bag wiring,
follow the procedures listed in “Disabling Air
Bag System” to temporarily disable the air
bag system.
Failure to follow procedures could result in
possible air bag system activation, personal
injury or unneeded air bag system repairs.

Side Curtain-Air Bag (Inflator) Module
Inspection
S7RS0B8206012
WARNING!
• Never measure resistance of side curtain-air bag (inflator) module or disassemble it.
Otherwise personal injury may result.
• Never attempt to disassemble or repair the side curtain-air bag (inflator) module. If any
abnormality is found, be sure to replace it
with new one as an assembly.
• Be sure to read “Precautions on Service and Diagnosis of Air Bag System”,
“Precautions on Handling and Storage of
Air Bag System Components” and
“Precautions on Disposal of Air Bag and
Seat Belt Pretensioner” before starting to
work and observe every precaution during
work. Neglecting them may result in
personal injury or undeployment of the air
bag when necessary.

CAUTION!
If air bag (inflator) module was dropped from
a height of 90 cm (3 ft) or more, it should be
replaced.

Check air bag (inflator) module appearance visually for
the following symptoms and if any one of them is found,
replace with a new one.
• Air bag has deployed.
• Inflator case being damaged or having been exposed to strong impact (dropped).
Forward-Sensor Removal and InstallationS7RS0B8206013
WARNING!
During service procedures, be very careful
when handling a sensor.
• Never strike or jar a sensor.
• A sensor and mounting bracket bolts must be carefully torqued to assure proper
operation. Under loose connection, it
could cause improper operation of the air
bag system.

Removal
1) Disconnect negative cable at battery.
2) Disable air bag system referring to “Disabling Air Bag System”.
3) Disconnect forward-sensor connector sliding connector outer (2) as shown.
4) Remove forward-sensor bolt (1) and forward-sensor (2).

Forward-Sensor InspectionS7RS0B8206014
WARNING!
During service procedures, be very careful
when handling a sensor.
• Never strike or jar a sensor.
• A sensor and mounting bracket bolts must be carefully torqued to assure proper
operation. Under loose connection, it
could cause improper operation of the air
bag system.

CAUTION!
• Never disassemble forward-sensor.
• Sensor should be replaced when it was dropped from a height of 90 cm (3 ft) or
more.

• Check sensor for dents, cracks or deformation.
• Check sensor connector (sensor side and harness side) and sensor connector lock mechanism for
damage or crack.
• Check connector terminals for bend, corrosion or rust.

Use of Special ToolsS7RS0B8208001
WARNING!
To avoid deployment when troubleshooting
the air bag system, do not use electrical test
equipment such as a battery powered or AC
powered voltmeter, ohmmeter, etc., or any
type of electrical equipment other than that
specified. Do not use a non-powered probe
type tester.
Instructions must be followed carefully,
otherwise personal injury may result.

You should be familiar with the tools listed under the
heading “Special Tool”. You should be able to measure
voltage and resistance. You should be familiar with
proper use of a scan tool such as Air Bag Driver /
Passenger Load Tool, Connector Test Adapter Kit and
the Digital Multimeter.
Special tool
(A): 09932–76010 Connector Test Adapter Kit
This must be used whenever a diagnostic procedure
requests checking or probing a terminal.
Using the appropriate adapter in the special tool will
ensure that no damage to the terminal will occur from the
multimeter probe, such as spreading or bending.
