(4) Connector twin±lock mechanism
With this mechanism connectors (male and female
connectors) are locked by 2 locking devices to in-
crease the connection reliability. If the primary lock
is incomplete, ribs interfere and prevent the sec-
ondary lock.
(b) When the vehicle is involved in a frontal collision in the
hatched area (Fig. 1) and the shock is larger than the pre-
determined level, the SRS is activated automatically. A
safing sensor is designed to go on at a smaller decelera-
tion rate than the airbag sensor. As illustrated in Fig. 2,
ignition is caused when current flows to the squib, which
happens when a safing sensor and the deceleration sen-
sor go on simultaneously. When a deceleration force acts
on the sensors, 2 squibs in the driver airbag and front pas-
senger airbag ignite and generate gas. The gas discharg-
ing into the driver airbag and front passenger airbag rap-
idly increases the pressure inside the bags, breaking
open the steering wheel pad and instrument panel door.
Bag inflation then ends, and the bags deflate as the gas
is discharged through discharge holes at the bag's rear or
side.

INSPECTION
1. VEHICLE NOT INVOLVED IN COLLISION
(a) Do a diagnostic system check.
(See page DI±626)
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) installed in the ve-
hicle.
Check cuts, minute cracks or marked discoloration on the
steering wheel pad top surface and in the grooved por-
tion.
2. VEHICLE INVOLVED IN COLLISION AND AIRBAG IS
NOT DEPLOYED
(a) Do a diagnostic system check.
(See page DI±626)
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.

Check cuts, minute cracks or marked discoloration
on the steering wheel pad top surface and in the
grooved portion.

Check cuts and cracks in wire harnesses, and chip-
ping in connectors.

Check the deformation of the horn button contact
plate on the steering wheel.
HINT:

If the horn button contact plate of the steering wheel is de-
formed, never repair it. Always replace the steering wheel
assembly with a new one.

There should be no interference between the steering
wheel pad and steering wheel, and the clearance should
be uniform all the way around when the new steering
wheel pad is installed on the steering wheel.
CAUTION:
For removal and installation of the steering wheel pad, see
page SR±11 and SR±16, and be sure to follow the correct
procedure.
3. VEHICLE INVOLVED IN COLLISION AND AIRBAG IS
DEPLOYED
(a) Do a diagnostic system check.
(See page DI±626)
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.

Check the deformation on the horn button contact
plate of the steering wheel.

Check the damage on the spiral cable connector
and wire harness.
HINT:

If the horn button contact plate of the steering wheel is de-
formed, never repair it. Always replace the steering wheel
assembly with a new one.

There should be no interference between the steering
wheel pad and steering wheel, and the clearance should
be uniform all the way around when the new steering
wheel pad is installed on the steering wheel.

DISPOSAL
HINT:
When scrapping vehicle equipped with an SRS or disposing of
a steering wheel pad (with airbag), always first deploy the air-
bag in accordance with the procedure described below. If any
abnormality occurs with the airbag deployment, contact the
SERVICE DEPT. of TOYOTA MOTOR SALES, U.S.A., INC.
When disposing of a steering wheel pad with an airbag
deployed in a collision, follow the same procedure given in step
1±(d) in ºDISPOSALº.
CAUTION:

Never dispose of a steering wheel pad which has an
undeployed airbag.

The airbag produces a sizeable exploding sound
when it deploys, so perform the operation out±of±
doors and 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 op-
eration in a place away from electrical noise.
SST 09082±00700

When deploying an airbag, perform the operation at
least 10 m (33 ft) away from the steering wheel pad.

The steering wheel pad is very hot when the airbag is
deployed, so leave it alone for at least 30 minutes af-
ter deployment.

Use gloves and safety glasses when handling a steer-
ing wheel pad with the deployed airbag.

Always wash your hands with water after completing
the operation.

Do not apply water, etc. to a steering wheel pad with
the deployed airbag.

1. AIRBAG DEPLOYMENT WHEN SCRAPPING VE-
HICLE
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Check functioning of the SST.
CAUTION:
When deploying the airbag, always use the specified SST:
SRS Airbag Deployment Tool.
SST 09082±00700
(1) Connect the SST to the battery.
Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip to the battery neg-
ative (±) terminal.
HINT:
Do not connect the yellow connector which will be connected
with the supplemental restraint system.
(2) Check functioning of the 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.
(b) Install the SST.
CAUTION:
Check that there is no looseness in the steering wheel and
steering wheel pad.
(1) Remove the steering column lower cover.
Remove the 3 screws and steering column lower
cover as shown in the illustration.
(2) Disconnect the airbag connector of the spiral cable.
