AIR BAG MODULE AND SEAT BELT PRE-TENSIONER
DISPOSAL PROCEDURES
M1524001200989
Before disposing of an air bag or a vehicle equipped
with an air bag, follow the procedures below to
deploy the air bag.
UNDEPLOYED AIR BAG MODULE DIS-
POSAL
WARNING
•
If the vehicle is to be scrapped or other-
wise disposed of, deploy the air bags and
operate the seat belt pre-tensioner inside
the vehicle. If the vehicle will continue to
be used and only the air bag modules and
seat belt pre-tensioner are to be disposed
of, deploy the air bags and operate the
seat belt pre-tensioner outside the vehi-
cle.
•
Since a large amount of smoke is pro-
duced when the air bag is deployed and
the seat belt pre-tensioner is operated,
avoid residential areas whenever possi-
ble.
•
Since there is loud noise when the air
bags are deployed and when the seat belt
pre-tensioner are operated, avoid residen-
tial areas whenever possible. If anyone is
nearby, give warning of the impending
noise.
•
Suitable ear protection should be worn by
personnel performing these procedures
or by people in the immediate area.
DEPLOYMENT INSIDE THE VEHICLE
(WHEN DISPOSING OF A VEHICLE)
<DRIVER'S AIR BAG MODULE>

DANGER
Wait at least 60 seconds after the disconnec-
tion of the battery cable before any further
job (Refer to
2. Disconnect the negative and positive battery
cables from the battery terminals, and then
remove the battery from the vehicle.
3. Remove the column cover lower (Refer to
GROUP 37
− Steering shaft
4. Remove the connection between the C-205 clock
spring connector (4-pin) and the harness side
connector (4-pin, yellow).
NOTE: Once disconnected from the instrument
panel wiring harness, both electrodes of the clock
spring connector short automatically. This pre-
vents the driver's air bag from accidental deploy-
ment caused by static, etc.
5. Obtain two suitable wires, which are 6 meters or
longer, as deployment wires. Then connect the
wires at one end to short.
6. Touch the vehicle's body with bare hands to
discharge static in you.
