Never attempt to disassemble the seat belt pretensioners (retrac-
tor assembly).
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 (inactivated)
seat belt pretensioner, be sure to activate it before discarding it.
When grease, cleaning agent oil, water, etc., got on the seat belt
pretensioners (retractor assembly), wipe it off immediately with a
dry cloth.
If seat belt pretensioner was dropped from a height of 30 cm (1
ft) or more, it should be replaced with a new one as an assembly.
WARNING:
For handling and storage of a live seat belt pretensioner,
select a place where the ambient temperature below 65C
(150F), without high humidity and away from electric
noise.
Never carry the seat belt pretensioner by the wires or con-
nector on the underside of the pretensioner.
When placing a live seat belt pretensioner on the work-
bench or some place like that, be sure not to lay it with its
exhaust hole provided side facing down. It is also prohib-
ited to put something on its face with an exhaust hole or
to put a seat belt pretensioner on top of another.
Otherwise, personal injury may result.

AIR BAG SYSTEM 10B-61
DEPLOYED AIR BAG (INFLATOR) MODULES
WARNING:
The air bag (inflator) module immediately after deploy-
ment is very hot. Wait for at least 30 minutes to cool it off
before proceeding the work.
Do not apply water, oil, etc. to deployed air bag (inflator)
module.
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 lubri-
cate the bag as it inflates) and byproducts 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 complet-
ing the work.
Refer to the procedure described under ªDeployed Air Bag (Inflator)
Modules Disposalº in this section.
ACTIVATED SEAT BELT PRETENSIONERS
WARNING:
The seat belt pretensioner immediately after activation is
very hot. Wait for at least 30 minutes to cool it off before
proceeding the work.
Do not apply water, oil, etc. to activated seat belt preten-
sioner.
With many service procedures, gloves and safety glasses
should be worn to prevent any possible irritation of the
skin or eyes.
Wash your hands with mild soap and water after complet-
ing the work.
Refer to the procedure described under ªActivated Seat Belt Pre-
tensioners Disposalº in this section.

1. Air bag wire harness
2. Ground
3. SDM case ground
AIR BAG WIRE HARNESS AND CONNECTORS
Air bag wire harness 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, damaged wire harness,
connector or terminal is found, replace wire harness, connectors
and terminals as an assembly.
When installing it, be careful so that the air bag wire harness is not
caught or does not interfere with other parts.
Make sure all air bag system grounding points are clean and
grounds are securely fastened for optimum metal-to-metal con-
tact. Poor grounding can cause intermittent problems that are dif-
ficult 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 the air bag according to deployment
procedure described under ªAir Bag (Inflator) Modules Disposalº
and to activate the pretensioner according to activation procedure
described under ªSeat Belt Pretensioners Disposalº.
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) module 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
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 sensors and 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 ªDiagnosisº when checking the SDM.
ACCIDENT WITH DEPLOYMENT ± COMPONENT
REPLACEMENT
Certain air bag system components must be replaced. Those com-
ponents are:
Driver and passenger air bag (inflator) modules
± Replace with new one.
Driver and passenger seat belt pretensioners
± Replace with new one as an assembly.
SDM after detecting such collision as to meet deployment condi-
tions
± Replace with new one.

PONENT INSPECTIONS
Certain air bag and restraint system components must be in-
spected after any crash, whether the air bag deployed or not.
Those components are:
Steering column and shaft joints
± Check for length, damage and bend according to ªChecking
Steering Column for Accident Damageº in SECTION 3C1.
Steering column bracket and capsules
± Check for damage and bent.
If any faulty condition is found in above checks, replace faulty
part.
Steering wheel and driver air bag (inflator) module
± Check for damage or air bag (inflator) module fitness.
± Check trim cover (pad surface) for cracks.
± Check wire harness and connector for damage or tightness.
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 tightness.
