AIR BAG SYSTEM 10B-51
DEPLOYED AIR BAG (INFLATOR) MODULE AND ACTI-
VATED SEAT BELT PRETENSIONER
Refer to the procedure described under “DEPLOYED AIR BAG
(INFLATOR) MODULE AND ACTIVATED SEAT BELT PRETEN-
SIONER DISPOSAL”. WARNING:
For handling and storage of a live seat belt preten-
sioner, select a place where the ambient temperature
below 65
°
°° °C (150
°
°° °F), without high humidity and away
from electric noise.
Never carry the seat belt pretensioner by the wire or
connector of the pretensioner.
When placing a live seat belt pretensioner on the work-
bench or other surface, be sure not to lay it with its
exhaust hole (1) provided side facing down. It is also
prohibited to put something on its face with an exhaust
hole (1) or to put a seat belt pretensioner on top of
another.
Otherwise, personal injury may result.
WARNING:
The air bag (inflator) module and seat belt pretensioner
immediately after deployment/activation is very hot.
Wait for at least 30 minutes to cool it off before pro-
ceeding the work.
Do not apply water, oil, etc. to deployed air bag (infla-
tor) module and to activate seat belt pretensioner.
After an air bag (inflator) module has been deployed,
the surface of the air bag may contain a powdery resi-
due. This powder consists primarily of cornstarch
(used to lubricate the bag as it inflates) and by-prod-
ucts of the chemical reaction. As with many service
procedures, gloves and safety glasses should be
worn.
Wash your hands with mild soap and water after com-
pleting the work.

10B-52 AIR BAG SYSTEM
AIR BAG WIRE HARNESS AND CONNECTOR
Air bag wire harness (1) can be identified easily as it is covered
with a yellow protection tube. Be very careful when handling it.
When an open in air bag wire harness (1), damaged wire
harness, connector or terminal is found, replace wire har-
ness, connectors and terminals as an assembly.
When installing it, be careful so that the air bag wire harness
(1) is not caught or does not interfere with other parts.
Make sure all air bag system grounding points (2) are clean
and grounds are securely fastened for optimum metal-to-
metal contact. Poor grounding can cause intermittent prob-
lems that are difficult to diagnose.
DISPOSAL
Do not dispose of the live (undeployed) air bag (inflator) modules
and the live (inactivated) seat belt pretensioners. When disposal
is necessary, be sure to deploy/activate the air bag and seat belt
pretensioner according to deployment/activation procedure
described in “AIR BAG (INFLATOR) MODULE AND SEAT BELT
PRETENSIONER DISPOSAL”.

WARNING:
Failure to follow proper air bag (inflator) module and seat
belt pretensioner disposal procedures can result in air
bag deployment and pretensioner activation which could
cause personal injury. Undeployed air bag (inflator) mod-
ule and inactivated seat belt pretensioner must not be
disposed of through normal refuse channels.
The undeployed air bag (inflator) module and inactivated
seat belt pretensioner contain substances that can cause
severe illness or personal injury if the sealed container is
damaged during disposal.

REPAIRS AND INSPECTIONS REQUIRED AFTER AN ACCIDENT
ACCIDENT WITH DEPLOYMENT/ACTIVA-
TION - COMPONENT REPLACEMENT
The following components must be replaced.
Driver and passenger air bag (inflator) modules
Driver and passenger seat belt pretensioners
SDM
–Replace with new one as an assembly.
ACCIDENT WITH OR WITHOUT DEPLOY-
MENT/ACTIVATION - COMPONENT INSPEC-
TIONS
Certain air bag system components must be inspected after any
crash, whether the air bag system activated or not.
Those components are :
Steering column (1) and shaft joints
–Check for length, damage and bend according to “CHECK-
ING STEERING COLUMN FOR ACCIDENT DAMAGE” in
SECTION 3C.
If any faulty condition is found in above checks, replace faulty
part.
Steering column bracket (2) and capsules (3)
–Check for damage and bent.
If any faulty condition is found in above checks, replace faulty
part. CAUTION:
All air bag system components, including the electrical harness (component mounting points),
must be inspected after an accident. If any components are damaged or bent, they must be
replaced even if air bag system activation did not occur.
Never use air bag system parts from another vehicle.
Do not attempt to service the parts below. Service of these parts is by replacement only.
–Driver/Passenger air bag (inflator) module, Driver/Passenger seat belt pretensioner
–SDM
–Contact coil and combination switch assembly
–Air bag wire harness
Proper operation of the air bag system requires that any repairs to the vehicle structure return it to
its original production configuration.
CAUTION:
After detecting one time of such collision as to meet deployment conditions, the SDM must not be
used. Refer to “AIR BAG DIAGNOSTIC SYSTEM CHECK” when checking the SDM.

10B-54 AIR BAG SYSTEM
Steering wheel and driver air bag (inflator) module
–Check for damage or air bag (inflator) module fitness.

ness.
If any faulty condition is found in above checks, replace faulty
part.
Contact coil and combination switch assembly
–Check wire harness and connectors for damage or tight-
ness.
–Check contact coil case for damage.
If any faulty condition is found in above checks, replace.
SDM and SDM plate
–Check for external damage such as deformation, scratch,
crack, peeled paint, etc.
–Check that SDM cannot be installed properly due to a
cause in itself. (There is a gap between SDM and SDM
plate, or it cannot be fixed securely.)
–Check that connector or lead wire of SDM has a scorching,
melting or damage.
–Check SDM connector and terminals for tightness.
–Check SDM sets a diagnostic trouble code (Refer to “DTC
CHECK”.) and the diagnostic table leads to a malfunction-
ing SDM.
If any faulty condition is found in above checks, replace.
