Toyota Corolla Repair Manual: Disposal
Hint
:
when scrapping vehicle equipped with an srs or disposing of a horn button assy,
always first deploy the
airbag in accordance with the procedure described below. If any abnormality
occurs in the airbag deployment,
contact the service dept. Of toyota motor sales, u.S.A., Inc.
Caution
:
- never dispose of a horn button assy which has an undeployed
airbag.
- The airbag produces a sizeable exploding sound
when it deploys, so perform the operation out of
doors and the place where it will not create a nuisance
to nearby residents.

- When deploying the airbag, always use the specified
sst (srs airbag deployment tool). Perform the operation
in a place away from electrical noise.
- When deploying an airbag, perform the operation at
least 10 m (33 ft) away from the horn button assy.
- The horn button assy is very hot when the airbag is
deployed, so leave it for at least 30 minutes after deployment.
- Use gloves and safety glasses when handling a horn
button assy with the deployed airbag.
- Always wash your hands with water after completing
the operation.
- Do not apply water, etc. To a horn button assy attached
on the deployed airbag.
1. Dispose of horn button assy (when
scrapping vehicle deployment method)

Hint
:
prepare a battery for the power source to deploy the airbag.

- Check the function of sst.
Caution
:
when deploying the airbag, always use the specified sst:
srs airbag deployment tool.
Sst 09082–00700

- Connect the sst to the battery.
Connect the red clip of the sst to the battery positive
(+) terminal and the black clip to the battery negative
(–) terminal.
Hint
:
do not connect the yellow connector which will be connected
with the supplemental restraint system.

- Check the function of sst.
Press the sst activation switch, and check that the
led of the sst activation switch lights up.
Caution
:
if the led lights up when the activation switch is not being
pressed, sst malfunction is probable, so definitely do not
use the sst.
- Disconnect the sst from the battery.

- Set sst.
Caution
:
check that there is no looseness in the steering wheel and
horn button assy.
- While turning the steering wheel to the right / left, remove
the 3 screws and column lower cover.
- Disconnect the airbag connector of the spiral cable.

- Connect the connectors of the 2 sst to the airbag
connector of the spiral cable back side.
Sst 09082–00700, 09082–00780

- Move the sst at least 10 m (33 ft) away from the
front of the vehicle.
- Close all the doors and windows of the vehicle.
Notice
:
take care not to damage the sst wire harness.
- Connect the red clip of the sst to the battery positive
(+) terminal and the black clip to the negative (–)
terminal.
- Deploy the airbag.
- Confirm that no one is inside the vehicle or within 10
m (33 ft) area around the vehicle.
- Press the sst activation switch and deploy the airbag.
Hint
:
the airbag deploys simultaneously when the led of the sst
activation switch lights up.
- dispose of the horn button assy (with airbag).
Caution
:
- the horn button assy is very hot when the airbag is
deployed, so leave it for at least 30 minutes after deployment.
- When moving a vehicle which has a horn button assy
with deployed airbag for scrapping, use gloves and
safety glasses.
- Use gloves and safety glasses when handling a horn
button assy with the deployed airbag.
- Always wash your hands with water after completing
the operation.
- Do not apply water, etc. To a horn button assy attached
on the deployed airbag.
Hint
:
when scrapping a vehicle, deploy the airbag and scrap the vehicle
with the horn button assy still installed.
2. Dispose of horn button assy (when
disposing of airbag assembly deployment
method)
Notice
:
- when disposing of the horn button assy (with airbag)
only, never use the customers vehicle to deploy the
airbag.
- Be sure to follow the procedure given below when deploying
the airbag.
Hint
:
prepare a battery for the power source to deploy the airbag.
- remove the horn button assy .
Caution
:
when storing the horn button assy, keep the upper surface
of the pad facing upward.

- Using a service–purpose wire harness, tie down the horn
button assy to the disc wheel.
Wire harness: stripped wire harness section
1.25 Mm2 or more (0.0019 In2. Or more)
Caution
:
if the wire harness is too thin or some other things are used
to tie down the horn button assy, it may be snapped by the
shock when the airbag is deployed. This is highly dangerous.
Be sure to use the wire harness which is at least 1.25
Mm2 (0.0019 In2).
Hint
:
to calculate the area of the stripped wire harness section:
area = 3.14 X (diameter)2 divided by 4

- Install the 2 bolts with washers in the 2 bolt holes in
the horn button assy.
Bolt:
l: 35.0 Mm (1.387 In.)
M: 6.0 Mm (0.236 In.)
Pitch: 1.0 Mm (0.039 In.)
Notice
:
- tighten the bolts by hand until the bolts become difficult
to turn.
- Do not tighten the bolts too much.

- Connect the connectors of the sst to the horn button
assy connectors.
Sst 09082–00802 (09082–10801, 09082–30801)

- Using 3 wire harness, wind the wire harness at least
twice each around the bolts installed on the left and
right sides of the horn button assy.
Caution
:
- tightly wind the wire harness around the bolts so that
there is no slack.
- If there is slack in the wire harness, the horn button
assy may come loose due to the shock when the airbag
is deployed. This is highly dangerous.

- Face the upper surface of the horn button assy upward.
Separately tie the left and right sides of the
horn button assy to the disc wheel through the hub
nut holes. Position the horn button assy connector
so that it hangs downward through a hub hole in the
disc wheel.
Caution
:
- make sure that the wire harness is tight. It is very dangerous
when the loosened wire harness results in the
horn button assy coming free through the shock from
the airbag deployment.
- Always tie down the horn button assy with the pad
side facing upward. It is very dangerous if the horn
button assy is tied down with the metal surface facing
upward as the wire harness will be cut by the shock
from the airbag deployment and the horn button assy
will be flown into the air.
Notice
:
the disc wheel will be marked by airbag deployment, so
when disposing of the airbag, use a redundant disc wheel.
- check the function of sst (see step 1–(a)).


- Set sst.
Caution
:
place the disc wheel on the level ground.
- Connect the connector of the sst.
Sst 09082–00700
Notice
:
to avoid damaging the sst connector and wire harness,
do not lock the secondary lock of the twin lock. Also, secure
some slack for the sst wire harness inside the disc
wheel.

- Move the sst at least 10 m (33 ft) away from the
horn button assy tied down on the disc wheel.

- Cover the horn button assy with a cardboard box or tires.
- Covering method using a cardboard box:
cover the horn button assy with the cardboard box
and weight the cardboard box down in 4 places with
at least 190 n (20 kg, 44 lb).
Size of cardboard box:
must exceed the following dimensions:
x = 460 mm (18.11 In.)
Y = 650 mm (25.59 In.)
Notice
:

- Covering method using tires:
place at least 3 tires without disc wheel on top of the
disc wheel with tire to which the horn button assy is
tied.
Tire size: must exceed the following dimensions–
width: 185 mm (7.28 In.)
Inner diameter: 360 mm (14.17 In.)
Caution
:
do not use tires with disc wheels.
Notice
:
the tires may be marked by the airbag deployment, so use
the redundant tires.

- Deploy the airbag.
- Connect the sst red clip to the battery positive (+)
terminal and the black clip to the battery negative
(–) terminal.
- Check that no one is within 10 m (33 ft) area around
the disc wheel which the horn button assy is tied to.
- Press the sst activation switch and deploy the airbag.
Hint
:
the airbag deploys simultaneously when the led of the sst
activation switch lights up.

- Dispose of the horn button assy (with airbag).
Caution
:
- the horn button assy is very hot when the airbag is
deployed, so leave it for at least 30 minutes after deployment.
- Use gloves and safety glasses when handling a horn
button assy with the deployed airbag.
- Always wash your hands with water after completing
the operation.
- Do not apply water, etc. To a horn button assy attached
on the deployed airbag.
- Remove the horn button assy from the disc wheel.
- Place the horn button assy in a vinyl bag, tie the end
tightly and dispose of it in the same way as other
general parts disposal.
