5. FRONT AIRBAG SENSOR
The front airbag sensor is mounted inside each of the front
members. The sensor unit is a mechanical type. When the sen-
sor detects deceleration force above a predetermined limit,
contact is made in the sensor, sending a signal to the airbag
sensor assembly. The sensor cannot be disassembled.

(a) All connectors in the SRS are colored yellow to distin-
guish them from other connectors. Connectors having
special functions and specifically designed for the SRS
are used in the locations shown above to ensure high reli-
ability. These connectors use durable gold−plated termi-
nals.
(1) Terminal Twin−Lock Mechanism
Each connector has a two−piece component con-
sisting of a housing and a spacer. This design se-
cures the locking of the terminal by two locking de-
vices (the retainer and the lance) to prevent
terminals from coming out.

(3) Electrical Connection Check Mechanism
This mechanism electrically checks if 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.
(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.

INSPECTION
1. VEHICLES NOT INVOLVED IN A COLLISION
(a) Do a diagnostic system check.
(See page DI−365)
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) installed in the ve-
hicle.
Check for cuts, minute cracks or marked discoloration on
the steering wheel pad top surface and in the grooved
portion.
2. VEHICLE INVOLVED IN A COLLISION AND AIRBAG IS
NOT DEPLOYED
(a) Do a diagnostic system check.
(See page DI−365)
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.
Check for cuts, minute cracks or marked discolor-
ation on the steering wheel pad top surface and in
the grooved portion.
Check for cuts and cracks in wire harness, and chip-
ping in connectors.
Check for the deformation of the horn button con-
tact plate of 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
the SR section and be sure to follow the correct procedure.
3. VEHICLE INVOLVED IN A COLLISION AND AIRBAG IS
DEPLOYED
(a) Do a diagnostic system check.
(See page DI−365)
(b) Do a visual check which includes the following items with
the steering wheel pad (with airbag) removed from the ve-
hicle.
Check for the deformation on the horn button con-
tact plate of the steering wheel.
Check for the damage to 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

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
CAUTION:
When deploying the airbag, always use the specified SST:
SRS Airbag Deployment Tool.
SST 09082−00700
(1) Connect the SST 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 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) Disconnect the airbag connector of the spiral cable.

(2) Connect the SST connector to the airbag connector
of the spiral cable.
SST 09082−00700
(3) Move the SST at least 10 m (33 ft) away from the
front of the vehicle.
(4) Close all the doors and windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(5) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the negative (−) termi-
nal.
(c) 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.
(d) Dispose of steering wheel pad (with airbag).
CAUTION:
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 deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a steering wheel pad with
deployed airbag.
(1) When scrapping a vehicle, deploy the airbag and
scrap the vehicle with the steering wheel pad still
installed.
(2) When moving a vehicle for scrapping which has a
steering wheel pad with deployed airbag, use
gloves and safety glasses.

steering wheel pad tied down on the disc wheel.
(f) Cover steering wheel pad with cardboard box or tires.
Covering method using cardboard box:
Cover the steering wheel pad 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:
