Servicing and Handling
WARNING!
Many of service procedures require
disconnection of “A/BAG” fuse and all air
bag (inflator) module(s) from initiator circuit
to avoid an accidental deployment.
Driver, Passenger, Side and Curtain Air Bag
(Inflator) Modules
• 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. When placing a live air bag
(inflator) module on a bench or other
surface, always face the bag up, away from
the surface. As the live passenger air bag
(inflator) module must be placed with its
bag (trim cover) facing up, place it on the
workbench with a slit (1) or use the
workbench vise (2) to hold it securely at its
lower mounting bracket (3). 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.
• Never dispose of live (undeployed) air bag (inflator) modules (driver, passenger, side
and curtain). If disposal is necessary, be
sure to deploy them according to
deployment procedures described in “Air
Bag (Inflator) Module and Seat Belt
Pretensioner Disposal in Section 8B”
before disposal.
• The air bag (inflator) module immediately
after deployment is very hot. Wait for at
least half an hour to cool it off before
proceeding the work.
• After an air bag (inflator) module has been deployed, the surface of the air bag may
contain a powdery residue. This powder
consists primarily of cornstarch (used to
lubricate the bag as it inflates) and by-
products of the chemical reaction. As with
many service procedures, gloves and
safety glasses should be worn.

[A]: Always carry air bag (inflator) module with trim cover (air bag opening) away from body.
[B]: Always place air bag (inflator) module on workbench with trim cover (air bag opening) up, away from loose objects.

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”.
