Disposal Procedures52B-64
AIR BAG MODULE AND SEAT BELT PRE-TENSIONER DISPOSAL
PROCEDURES
Carry out the following procedure of air bag
deployment and seat belt pre-tensioner operation
before disposing the air bag module and seat beltwith pre-tensioner or the vehicle with SRS air bag
and seat belt with pre-tensioner.
DISPOSAL OF AIR BAG MODULE BEFORE
DEPLOYMENT OR SEAT BELT WITH
PRE-TENSIONER BEFORE OPERATION
Caution
1. Carry out deployment of all the air bag modules and
operation of all seat belt pre-tensioners before
disposing the vehicle with SRS air bag and seat belt
with pre-tensioner inside the vehicle.
2. Carry out deployment of the used air bag or operation
of the used seat belt pre-tensioner outside the vehicle
when replacing the air bag module or the seat belt with
pre-tensioner.
3. Carry out deployment of air bag or operation of seat
belt pre-tensioner in a well ventilated place since a lot
of smoke is generated .Do not carry out operation near
a smoke detector.
4. Avoid carrying out operation in a residential area as
much as possible and give a warning when any person
is near by since air bag deployment or seat belt
pre-tensioner operation causes loud operation sound.
5. Prepare ear plugs for those are engaged in air bag
deployment or seat belt pre-tensioner operation or for
those who are near by.
DEPLOYMENT OR OPERATION INSIDE THE VEHICLE
1. Move the vehicle to flat and isolated spot.
2. Disconnect the negative (–) and positive (+) battery cables
from the battery terminals, and then remove the battery
from the vehicle.
Caution
Wait at least 60 seconds after the disconnection of the
battery cables before any further job. (Refer to
P.52B-3.)
3. Carry out deployment of the air bag module and operation
of the seat belt pre-tensioner according to the following
procedure.

SRS -AirBagModuleandSeatBeltPre-tensioner
Disposal Procedures52B-65
Driver’s air bag module
(1) Remove the steering column cover, lower.
(Refer to GROUP 52A – Instrument Panel.)
(2) Disconnect the clock spring 2-pin connector and
instrument panel wiring harness connector (2-pin,
yellow).
NOTE
Once disconnected from the instrument panel wiring
harness, both electrodes of the clock spring connector
short automatically. This prevents the driver’s air bag
from accidental deployment caused by static, etc.
(3) Connect deployment harnesses longer than 6 m to
each SRS air bag adapter harness and insulate the
connections with plastic tape.
Also, connect the deployment harnesses in the other
ends to short, thereby preventing the driver’s air bag
from accidental deployment caused by static etc.
(4) Connect the SRS air bag adapter harness to the
clock spring 2-pin connector and route the deployment
harnesses out of the vehicle.
(5) Close all the doors with the windows fully closed and
put a cover over the vehicle to minimize report.
Caution
The cover is required as the glass, if already
damaged, may break.
(6) Separate the deployment harnesses as far from the
vehicle as possible and connect to the terminals of the
battery removed from the vehicle. Then deploy.
Caution
1) Before deploying the air bag, see that no one is in
and near the vehicle. Also, put on safety glasses.
2) The deployment makes the inflator of the
driver’s air bag very hot. Before handling the
inflator, wait more than 30 minutes for cooling.
3) If the driver’s air bag module fails to deploy
although the procedure is respected, do not go
near the module. Contact your local distributor.
(7) Discard the deployed air bag module according to
Deployed Air Bag Module Disposal Procedures.
(Refer to P.52B-75.)

connector (red) and instrument panel wiring harness
connector (2-pin, red).
NOTE
Once disconnected from the instrument panel wiring
harness, both electrodes of the front passenger’s air
bag module short automatically. This prevents the
front passenger air bag from accidental deployment
caused by static, etc.
(3) Connect deployment harnesses longer than 6 m to
each SRS air bag adapter harness and insulate the
connections with plastic tape.
Also, connect the deployment harnesses in the other
ends to short, thereby preventing the front

(4) Connect the SRS air bag adapter harness to the
front passenger’s air bag module 2-pin connector
(red) and route the deployment harnesses out of the
vehicle.
(5) Close all the doors with the windows fully closed and
put a cover over the vehicle to minimize report.
Caution
The cover is required as the glass, if already
damaged, may break.

vehicle as possible and connect to the terminals of the
battery removed from the vehicle. Then deploy.
Caution
1) Before deploying the air bag, see that no one is
in and near the vehicle. Also, put on safety
glasses.
2) The deployment makes the inflator of the front
passenger’s air bag very hot. Before handling
the inflator, wait more than 30 minutes for
cooling.
3) If the front passenger’s air bag module fails to
deploy although the procedure is respected,
do not go near the module. Contact your local
distributor.
(7) Discard the deployed air bag module according to
Deployed Air Bag Module Disposal Procedures.
(Refer to P.52B-75.)
Seat belt pre-tensioner
(1) Remove the center pillar lower trim.
(Refer to GROUP 52A - Instrument Panel.)
(2) Disconnect the seat belt pre-tensioner 2 - pin
connector (red) from the floor wiring harness
connector (2 - pin, red).
NOTE
Once disconnected from the floor wiring harness, both
electrodes of the seat belt pre-tensioner connector
short-circuit automatically. This prevents the seat belt
pre-tensioner from accidental deployment caused by
static, and etc.
(3) Connect deployment harnesses longer than 6 m to
each SRS air bag adapter harness and insulate the
connections with plastic tape.
Also, connect the deployment harnesses in the other
ends to short, thereby preventing the seat belt
pre-tensioner from accidental deployment caused by
static etc.
(4) Connect the SRS air bag adapter harness to the
seat belt pre-tensioner 2 - pin connector (red) and pull
out the operation harness.

Caution
1) Before operating the seat belt pre-tensioner,
see that no one is in or near the vehicle.
2) The operation makes the insulator of the seat
belt pre-tensioner very hot. Before handling
the inflator, wait more than 30 minutes for
cooling.
3) If the seat belt pre-tensioner fails to operate
although the procedure is respected, do not go
near the seat belt pre-tensioner. Contact your
local distributor.
(7) Discard the operated seat belt pre-tensioner accord-
ing to Disposal Procedure. (Refer to P.52B-75.)
DEPLOYMENT OUTSIDE THE VEHICLE
Caution
1. Carry out air bag deployment or seat belt pre-tensioner
operation on large flat place at least 6 m away from any
object or person.
2. Avoid a strong wind weather when carrying out
deployment or operation outside the vehicle. Ignite the
air bag at a place upwind from the air bag module and
the seat belt pre-tensioner even in a breeze weather.
1. Disconnect the negative ( - ) and positive (+) battery cables
from the battery terminals, and then remove the battery
from the vehicle.
Caution
Wait at least 60 seconds before any further job after the
disconnection of the battery cables. (Refer to P.52B-3.)
2. Carry out deployment of the air bag module and operation
of the seat belt pre-tensioner according to the following
procedure.
Driver’s side air bag module
type>
(1) Remove the driver’s air bag module from the vehicle.
(Refer to P.52B-52.)
Caution
Once disconnected, both electrodes of the driver’s air
bag module connector short automatically to prevent
accidental deployment caused by static etc. Still, in
consideration of the accidental deployment, store the
air bag module on flat place with deployment surface
facing up. Also, do not put anything on it.
