Precautions for Vehicles Equipped with a
Supplemental Restraint (Air Bag) System
S7RS0B0000001
WARNING!
• The configuration of air bag system parts are as shown in the figure. When it is
necessary to service (remove, reinstall and
inspect) these parts, be sure to follow
procedures described in Air Bag System
section. Failure to follow proper
procedures could result in possible air bag
system activation, personal injury, damage
to parts or air bag system being unable to
activate when necessary.
• 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 air bag system
components. Modifications can adversely
affect air bag system performance and
lead to injury.
• 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 air bag system activation.

Diagnosis
• When troubleshooting air bag system, be sure to follow “Diagnosis” in Air Bag System section.
Bypassing these procedures may result in extended
diagnostic time, incorrect diagnosis, and incorrect
parts replacement.
• Never use electrical test equipment other than that specified.
WARNING!
Never attempt to measure the resistance of
the air bag (inflator) modules (driver,
passenger, side and curtain) and seat belt
pretensioners (driver and passenger). It is
very dangerous as the electric current from
the tester may deploy the air bag or activate
the pretensioner.

1. Air bag wire harness (in floor, main and instrument panel harness) 6. Driver air bag (inflator) module
2. Passenger air bag (inflator) module 7. Side air bag (inflator) module (if equipped)
3. SDM 8. Curtain air bag (inflator) module (if equipped)
4. Seat belt pretensioner 9. Forward sensor
5. Contact coil 10. Side sensor (if equipped)

WARNING!
SDM
• For handling and storage of a SDM, select a place where the ambient temperature
below 65 °C (150 °F), without high humidity
and away from electric noise.
• During service procedures, be very careful when handling a Sensing and Diagnostic
Module (SDM). Never strike or jar the SDM.
• Never power up the air bag system when the SDM is not rigidly attached to the
vehicle. All SDM and mounting bracket
fasteners must be carefully torqued and
the arrow must be pointing toward the
front of the vehicle to ensure proper
operation of the air bag system.
The SDM could be activated when powered
while not rigidly att ached to the vehicle
which could cause deployment and result
in personal injury.

WARNING!
Driver and Passenger Seat Belt
Pretensioners
• For handling and storage of a live seat belt pretensioner, select a place where the
ambient temperature below 65 °C (150 ° F),
without high humidity and away from
electric noise.
• Never carry seat belt pretensioner by wire or connector of pretensioner. When
placing a live seat belt pretensioner on the
workbench or some place like that, never
put something on seat belt pretensioner.
Otherwise, personal injury may result.
• Never dispose of live (inactivated) seat belt pretensioners (drive and passenger). If
disposal is necessary, be sure to activate
them according to activation procedures
described in “Air Bag (Inflator) Module and
Seat Belt Pretensioner Disposal in Section
8B” before disposal.
• The seat belt pretensioner immediately after activation is very hot. Wait for at least
half an hour to cool it off before
proceeding the work.
• With many service procedures, gloves and safety glasses should be worn to prevent
any possible irritation of the skin or eyes.

• Even when the accident was light enough not to cause air bags to activate, be sure to inspect system
parts and other related parts according to instructions
under “Repair and Inspection Required after Accident
in Section 8B”.
• When servicing parts other than air bag system, if shocks may be applied to air bag system component
parts, remove those parts beforehand.
• When handling the air bag (inflator) modules (driver, passenger, side and curtain), seat belt pretensioners
(driver and passenger), forward sensor, side sensors
or SDM, be careful not to drop it or apply an impact to
it. If an excessive impact was applied, never attempt
disassembly or repair but replace it with a new one.
• When grease, cleaning agent, oil, water, etc. has got onto air bag (inflator) modules (driver, passenger, side
and curtain) or seat belt pretensioners (drive and
passenger), wipe off immediately with a dry cloth.
• Air bag wire harness is included in floor and instrument panel wire harnesses. Air bag wire
harness branched off from floor and instrument panel
wire harnesses can be identifie d easily as it is covered
with a yellow protection tube and it has yellow
connectors. Be very ca reful when handling it.
• When an open in air bag wire harness, damaged wire harness, connector or terminal is found, replace wire
harness, connectors and terminals as an assembly.
• 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.
• Never use air bag system component parts from another vehicle.
• When using electric welding, be sure to disconnect all air bag (inflator) module connectors and pretensioner
connectors from air bag wire harness respectively.
• Never expose air bag system component parts directly to hot air (drying or baking the vehicle after
painting) or flames.
• WARNING / CAUTION labels are attached on each
part of air bag system components. Be sure to follow
the instructions.
• After vehicle is completely repaired, perform “Air Bag Diagnostic System Check in Section 8B”.

Downloaded from www.Manualslib.com manuals search engine 1A-8 Engine General Information and Diagnosis:
CAN communication system uses the serial communication in which data is transmitted at a high speed. It uses a
twisted pair of two communication lines for the high-speed da ta transmission. As one of its characteristics, multiple
control modules can communicate simultaneously. In addition, it has a function to detect a communication error
automatically. Each module reads necessary data from the received data and transmits data. ECM communicates
control data with each control module as follows.
ECM Transmission Data
NOTE
• In communication between ECM and combination meter and between ECM and steering angle sensor (ESP ® model), data is transmitted only from ECM to combination meter and steering angle
sensor. (Combination meter and steering angle sensor does not transmit data to ECM.)
