HINT:
The type of connector shown on the previous page is used for
the spiral cable connector º5º on the airbag sensor assembly
side.
(3) Electrical Connection Check Mechanism
This mechanism electrically checks that connectors
are connected correctly and completely. The electri-
cal connection check mechanism is designed so
that the disconnection detection pin connects with
the diagnosis terminals when the connector hous-
ing lock is locked.
HINT:
The above illustration shows connectors º1º, º2º and º3º.

11. DISCONNECTION OF AIRBAG SENSOR CONNEC-
TOR
(a) With holding both flank sides of the outer, slide the outer
to the direction shown by an arrow.
(b) When lock of the connectors is released disconnect the
connector.
HINT:
Make sure to hold both flank sides of the outer. If holding the top
and bottom sides, it obstructs disconnection.
12. CONNECTION OF AIRBAG SENSOR CONNECTOR
(a) Align the male connector (on the side of sensor) and fe-
male connector in the same direction as shown in the il-
lustration and fit in them without rubbing.
(b) As they are fitted in, the outer slides rearward. Press it un-
til the outer returns to its original position again.
If fitting stops on the half way, connectors will separate.
(c) Make sure to insert until the connectors are locked. After
fitting in, pull them lightly to check that they are locked.
(When locked, make sure that the outer returns to its origi-
nal position and sound at the time of fitting in can be
heard.)
HINT:
Do not fit in with holding the outer.
When fitting in, the outer slides. Do not touch it.

14. CONNECTION OF SIDE AIRBAG CONNECTOR
(a) Align the male connector and the female connector in the
same direction as shown in the illustration, fit in them with-
out rubbing.
(b) Make sure to insert until the connectors are locked. After
fitting in, pull them lightly to check that they are locked.
(When locked, make sure that the outer returns to its origi-
nal position and sound at the time of fitting in can be
heard.)
HINT:
As the slider slides, do not touch it.
Be careful not to deform the release board. If the release
board is deformed, replace it with a new one.

1. AIRBAG DEPLOYMENT WHEN SCRAPPING VE-
HICLE
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Check functioning of SST.
(See page RS±17)
SST 09082±00700, 09082±00760
(b) Disconnect the airbag connector.
(1) Using a screwdriver, remove the glove compart-
ment door finish plate.
HINT:
Tape the screwdriver tip before use.
(2) Remove the airbag connector from the plate.
(3) Disconnect the airbag connector.
(c) Install the SST.
(1) Connect the 2 SST each other, then connect them
to the airbag connector of the spiral cable.
SST 09082±00700, 09082±00760
NOTICE:
To avoid damage to the SST connector and wire harness,
do not lock the secondary lock of the twin lock.
(2) Move the SST at least 10 m (33 ft) away from the
front of the vehicle.
(3) Close all the doors and windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(4) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the battery negative
(±) terminal.
(d) Deploy the airbag.
(1) Check that no one is inside the vehicle or within 10
m (33 ft) area around the vehicle.
(2) Press the SST activation switch and deploy the air-
bag.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.

(e) Place the tires
(1) Place at least 2 tires under the tire to which the front
passenger airbag assembly is tied.
(2) Place at least 2 tires over the tire to which the front
passenger airbag assembly is tied. The top tier
should have the wheel installed.
(3) Tie the tires together with 2 wire harness.
CAUTION:
Make sure that the wire harness is tight. It is very danger-
ous when loose wire harness results in the tires coming
free due to the shock from the airbag deploying.
HINT:
Place the SST connector and wire harness inside tires. Secure
at least 1 m (3 ft) of slack for the wire harness.
(f) Deploy the airbag.
(1) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the battery negative(±)
terminal.
(2) Check that no one is within 10 m (33 ft) area around
the tire which the front passenger airbag assembly
is tied to.
(3) Press the SST activation switch and deploy the air-
bag.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.
(g) Dispose of front passenger airbag assembly.
CAUTION:

The front passenger airbag assembly is very hot
when the airbag is deployed, so leave it alone for at
least 30 minutes after deployment.

Use gloves and safety glasses when handling a front
passenger airbag assembly with the deployed airbag.

Always wash your hands with water after completing
the operation.

never use the customer's vehicle to deploy the air-
bag.

Be sure to follow the procedure given below when de-
ploying the airbag.
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Remove the seatback assembly (See page RS±40).
