Accident with or without Deployment / Activation –
Component Inspections
Certain air bag and restraint system components must
be inspected after any crash, whether the air bag system
activated or not. If any faulty condition is found in the
following checks, replace faulty part.
Those components are:
• Steering column (1) and shaft joints
– Check for length, damage and bend according to
“Checking Steering Column for Accident Damage in
Section 6B”.
• Steering column bracket (2) and capsules
– Check for damage and bent.
• 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.• Contact coil assembly
– Check wire harness and connectors for damage or
tightness.
– Check contact coil case for damage.
– Check contact coil circuit referring to “Contact Coil
Cable and Its Circuit Check”.
• Instrument panel member and reinforcement
– Check for any distortion, bending, cracking or other
damage.
– Check instrument panel for cracks or deformities.
• Passenger air bag (inflator) module
– Check for dents, cracks, damage or fitness.
– Check harness and connector for damage or
tightness.
•SDM
– Check for external damage such as deformation,
scratch, crack, peeled paint, etc.
– Check SDM for a cause in itself preventing its
proper installation. (There is a gap between SDM
and SDM plate, or it cannot be fixed securely.)

• For seat belt pretensioner
a. Cut webbing (1) at tongue plate stopper (3) of
seat belt pretensioner (2) side as shown.
NOTE
Hold seat belt pretensioner (2) vertically in
the same condition as it is installed.
Otherwise, webbing can’t be pulled out.
b. Remove tongue plate (4) and shoulder anchor
(5) from webbing.
c. Tie webbing (1) tightly at 10 cm (3.9 in.) from
cutting edge as shown.
d. Tie seat belt pretensioner (2) with wire
harness (3) to wheel-installed tire (4) as
shown.
Wire harness specifications
Stripped wire harness section 1.25 mm2
(0.0019 in.2) or more (Stripped wire harness
diameter 1.25 mm (0.05 in.) or more)
NOTE
Wind wire harness (3) around at least 3 times.
e. Clear space (5) on ground about 185 cm (6 ft)
in diameter where seat belt pretensioner (2) is
to be activated. Paved, outdoor location where
there is no activity is preferred. If outdoor
location is not available, use space on shop
floor where there is no activity and sufficient
ventilation is provided. Ensure no loose or
flammable object exists within activation area.
f. Place wheel-installed tire (4) with seat belt
pretensioner (2) on ground in Step e.
7) Stretch deployment harness (A) from air bag
(inflator) module or seat belt pretensioner to its full
length 10 m (33 ft).
Special tool
(A): 09932-75031
8) Place 12 volts vehicle battery (1) near the shorted
end of deployment harness (A).
9) Check that area around air bag (inflator) module or
seat belt pretensioner is clear of all people and loose
or flammable objects.

8) Route deployment harness (1) out of vehicle.
9) Check that inside of vehicle and area surrounding
vehicle are clear of all people and loose or
flammable objects.
10) Stretch deployment harness (1) to its full length 10 m
(33 ft).
11) Place 12 volts vehicle battery (2) near shorted end of
deployment harness (1).
12) Completely cover windshield area and front door
window openings with drop cloth, a blanket or any
similar item. This reduces possibility of injury due to
possible fragmentation of vehicle’s glass or interior.
13) Notify all people in immediate area that you intend to
deploy air bag (inflator) module or activate seat belt
pretensioners.
NOTE
• When air bag (inflator) module deploys or
seat belt pretensioners activate, rapid gas
expansion will create substantial report.
Wear suitable ear protection. Notify all
people in immediate area that you intend
to deploy air bag (inflator) module or to
activate seat belt pretensioner and suitable
ear protection should be worn.
• After air bag (inflator) module has been
deployed, surface of air bag may contain
powdery residue. This powder consists
primarily of cornstarch (used to lubricate
air bag (inflator) module as it inflates) and
by-products of chemical reaction.
WARNING!
• Do not place deployed air bag (inflator)
module and activated seat belt
pretensioners near any flammable objects.
• Do not apply water, oil, etc. to deployed air
bag (inflator) module and activated seat
belt pretensioners.
• Wait for about 30 minutes before touching
any metal surface of air bag (inflater)
module or seat belt pretensioner modules.
Disregarding these precautions may cause
fire or personal injury.
Failure to follow procedures may result in fire
or personal injury.
14) Separate two banana plugs (1) on deployment
harness (2).
15) Connect deployment harness (2) to 12 volts vehicle
battery (3). This will immediately deploy or activate
air bag (inflator) module or seat belt pretensioners.
16) Disconnect deployment harness (2) from 12 volts
vehicle battery (3) and short two deployment
harness leads together by fully seating one banana
plug into the other.
17) Repeat Steps 3) through 16) to deploy / activate air
bag (inflator) modules and seat belt pretensioners
which has not been deployed / activated, if any.
18) In the unlikely event that air bag (inflator) module
and seat belt pretensioners after following these
procedures, proceed immediately with Step 24)
through 26). If air bag (inflator) module and seat belt
pretensioners did deploy / activate, proceed with
Steps 19) through 23).
19) Carefully remove drop cloth from vehicle and clean
off any fragments or discard it entirely.
20) Put on pair of shop gloves to protect your hands from
possible irritation and heat when handling deployed
air bag (inflator) module and activated seat belt
pretensioners.
