Precautions on Service and Diagnosis of Air
Bag System
S6RW0D8200004
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/B” fuse and air bag (inflator) module(s) (driver
module, passenger module, side modules and curtain
modules) 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 light operation 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
module, passenger module, side modules and curtain
modules), seat belt pretensioners (driver module and
passenger module), SDM, forward impact-sensor or
side impact-sensor be careful not to drop it or apply
an impact to it. If an excessive impact was applied
(e.g., SDM, forward impact-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 module,
passenger module, side modules and curtain
modules) and seat belt pretensioner connectors
(driver module and passenger module) 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.

SDM
WARNING!
Never power up air bag system when SDM is
not rigidly attached to the vehicle. Otherwise,
personal injury may result.

CAUTION!
After detecting one time of such collision as
to meet deployment conditions, SDM must
not be used. Refer to “Air Bag Diagnostic
System Check” when checking SDM.

Air Bag Diagnostic System Check FlowS6RW0D8204002
CAUTION!
• Be sure to perform “Air Bag Diagnostic System Check” before starting diagnosis according to each
flow.
• When measurement of resistance or voltage is required in the flow, use a tester along with a correct
terminal adapter from special tool (Connector test adapter kit).
• When a check for proper connection is required, refer to “Inspection of Intermittent and Poor
Connections”.
• If an open circuit in the air bag wire harness damaged, connector or terminal is found, replace the
wire harness, connectors and terminals as an assembly.

DTC TableS6RW0D8204003
NOTE
The DTCs (B1022 and B1023) shown with asterisk (*) below have been established only for the M15A
engine model with 4A/T equipped with slip-control (i.e., Hong Kong model). These codes are meant to
be recorded when External Scrapping Deployment Controller is operated by a Japanese authorized
special scrapping trader. Therefore, normally these codes will not appear outside Japan. However,
should these codes be detected, SDM must be replaced because the cause is due to SDM detection
failure.

details.
If communication between scan tool and SDM is not
possible, check if scan tool is communicable by
connecting it to SDM in another vehicle. If
communication is possible in this case, scan tool is
in good condition. Then check data link connector
and serial data line (circuit) in the vehicle with which
communication was not possible.
If connector and circuit are OK, check that DLC
circuit and power supply and ground circuits of SDM
are in good condition referring to “SDM Power
Supply and Ground Circuit Check” and “Serial Data
Link Circuit Check”.
5) After completing the check, turn ignition switch to
OFF position and disconnect SUZUKI scan tool from
data link connector (DLC) (1).
