Precautions on Service and Diagnosis of Air 
Bag System

S5JB0A8200001

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, 
passenger, side of both sides 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 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 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 sides and curtain of both 
sides), seat belt pretensioners (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 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.

 

Precautions on Handling and Storage of Air Bag 
System Components

S5JB0A8200002

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.

 

8B-2 Air Bag System: 

• Never attempt disassembly of SDM.
• When storing SDM, select a place where neither high 

temperature nor high humidity is anticipated and oil, 
water and dust are kept off.

• If SDM has been dropped, replace it with a new one.
• If SDM installation part of floor was damaged, repair 

that part completely before reinstallation.

• All SDM and mounting bracket fasteners must be 

carefully torqued and the arrow must be pointed 
toward the front of the vehicle to ensure proper 
operation of the air bag system.

Live (Undeployed) Air Bag (Inflator) Modules
Special care is necessary when handling and storing a 
live (undeployed) air bag (inflator) modules.
The rapid gas generation produced during deployment 
of the air bag could cause the air bag (inflator) module, 
or an object in front of the air bag (inflator) module, to be 
thrown through the air in the unlikely event of an 
accidental deployment.

WARNING

!

 

Never attempt to measure the resistance of 
the air bag (inflator) modules (driver, 
passenger and side of both sides and curtain 
of both sides). It is very dangerous as the 
electric current from the tester may deploy 
the air bag.

 

• Never attempt disassembly of the air bag (inflator) 

modules.

• If any abnormality is found, be sure to replace it with 

new one as an assembly.

• When an abnormality is noted as existing in the live 

(undeployed) air bag (inflator) module, be sure to 
deploy it before discarding it.

• When grease, cleaning agent, oil, water, etc., got on 

the air bag (inflator) modules (driver, passenger, side 
of both sides and curtain of both sides), wipe it off 
immediately with a dry cloth.

• If air bag (inflator) module was dropped from a height 

of 90 cm (3 ft) or more, it should be replaced with a 
new one as an assembly.

Air Bag System:  8B-3

WARNING

!

 

• 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.

Otherwise, personal injury may result.

 

WARNING

!

 

When leaving or storing live air bag (inflator) 
module unattended on bench or other 
surface, always its bag (trim cover) facing up 
and away from surface.
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.

 

Live (Inactivated) Seat Belt Pretensioner
Special care is necessary when handling and storing a 
live (inactivated) seat belt pretensioners.
Also, when the seat belt pretensioners activate, gas is 
generated and the seat belt (1) is retracted into the 
retractor assembly (2) quickly.
Note, therefore, that if they activate accidentally, the seat 
belt pretensioners and other object(s) around them may 
be thrown through the air.

WARNING

!

 

Never attempt to measure the resistance of 
the seat belt pretensioners. It is very 
dangerous as the electric current from the 
tester may activate pretensioner.
