DISPOSAL

WARNING

•

If the vehicle is to be scrapped or
otherwise 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 vehicle.

•

Since a large amount of smoke is
produced when the air bag is deployed
and the seat belt pre-tensioner is
operated, avoid residential areas
whenever possible.

•

Since there is loud noise when the air
bags are deployed and when the seat belt
pre-tensioner are operated, avoid
residential 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) <AIR
BAG MODULE (DRIVER'S SIDE)>

1. Move the vehicle to an isolated spot.

DANGER

Wait at least 60 seconds after the
disconnection of the battery cable before
any further job (Refer to

P.52B-7

).

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

P.37-16

).

4. Remove the connection between the C-309 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
prevents the driver's air bag from accidental
deployment 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.
NOTE: This prevents the air bag from
unintentional deployment caused by static
electricity, etc.

7. Cut with a pliers, etc. the instrument panel wiring

harness shown in the figure of the instructions,
while the C-309 clock spring connector is
disconnected.
