Precautions on Service and Diagnosis of Air
Bag System
S3RH0A8200001
NOTE
Upon completion of inspection and repair
work, perform following items.
• Reconnect all air bag system components,
ensure all components are properly
mounted.
• Clear diagnostic trouble code (Refer to
“DTC Clearance”), if any.
• Repeat “Air Bag Diagnostic System
Check” to confirm that the trouble has
been corrected.
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.
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 or any other on or around air
bag system components. Modifications
can adversely affect air bag system
performance and lead to injury.
• Failure to follow procedures could result in
possible air bag system activation,
personal injury or unneeded air bag
system repairs.
• Many of service procedures require disconnection of
“AIR BAG” fuse and air bag (inflator) module(s)
(driver, passenger and side of driver and passenger)
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 System Check” must be the
starting point of any air bag diagnostics. The “Air Bag
Diagnostic System Check” will verify proper “AIR
BAG” warning lamp operation and will lead you to the
correct table 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 and side of driver and passenger), seat
belt pretensioners (driver and passenger), side
sensors or SDM, be careful not to drop it or apply an
impact to it. If an excessive impact was applied (e.g.,
side sensors are dropped, SDM is 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
and side of driver and passenger) 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 exposed 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.
