INSPECTION
1. VEHICLE NOT INVOLVED IN COLLISION
(a) Perform a diagnostic system check (see page DI±1147).
(b) With the front passenger airbag assembly installed on the
vehicle, perform a visual check. If there are any defects
as mentioned below, replace the front passenger airbag
assembly with a new one:
Cuts, minute cracks or marked discoloration on the instru-
ment panel around the front passenger airbag assembly.
2. VEHICLE INVOLVED IN A COLLISION AND AIRBAG IS
NOT DEPLOYED
(a) Perform a diagnostic system check (see page DI±1147).
(b) With the front passenger airbag assembly removed from
the vehicle, perform a visual check. If there are any de-
fects as mentioned below, replace the front passenger
airbag assembly, instrument panel or instrument panel re-
inforcement with a new one:

Cuts, minute cracks or marked discoloration on the
front passenger airbag assembly.

Cracks or other damage to the connectors.

Deformation or cracks on the instrument panel or
instrument panel reinforcement.

DISPOSAL
HINT:
When scrapping a vehicle equipped with the SRS or disposing
of the front passenger airbag assembly, be sure to deploy the
airbag first in accordance with the procedure described below.
If any abnormality occurs with the airbag deployment, contact
the SERVICE DEPT. of the TOYOTA MOTOR SALES, U.S.A.,
INC.
CAUTION:

Never dispose of a front passenger airbag assembly
that has an undeployed airbag.

The airbag produces an exploding sound when it is
deployed, so perform the operation outdoors and
where it will not create a nuisance to nearby resi-
dents.

When deploying the airbag, always use the specified
SST (SRS Airbag Deployment Tool). Perform the op-
eration in a place away from electrical noise.

When deploying the airbag, perform the operation at
least 10 m (33 ft) away from the front passenger air-
bag assembly.

The front passenger airbag assembly becomes ex-
tremely hot when the airbag is deployed, so do not
touch it for at least 30 minutes after deployment.

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

Do not apply water, etc. to a front passenger airbag
assembly with a deployed airbag.

Always wash your hands with water after completing
the operation.
HINT:
Prepare a battery as the power source to deploy the airbag.

1. AIRBAG DEPLOYMENT WHEN SCRAPPING VE-
HICLE
(a) Check the function of the SST (see step 1±(a) on page
RS±23).
(b) Precaution (see page RS±1 and RS±3).
(c) Disconnect the cable from the negative battery terminal.
Wait for 90 seconds after disconnecting the cable to prevent the
airbag working.
(d) Remove the glove compartment door (see page
BO±89).
(e) Remove the lower No. 2 finish panel (see page
BO±89).
(f) Disconnect the airbag connector (yellow colored one)
from the front passenger airbag assembly.
(1) Using a clip remover, disengage the connector
clamp.
(2) Disconnect the airbag connector.
NOTICE:
When handling the airbag connector, take care not to dam-
age the airbag wire harness.
(g) Install the SST.
(1) Connect the SST connector to the front passenger
airbag assembly.
SST 09082±00700, 09082±00780
NOTICE:
To avoid damaging 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 ve-
hicle side window.
(3) Maintaining enough clearance for the SST wire har-
ness in the front side window, close all doors and
windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(4) Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip of the SST to the
negative (±) terminal.

(h) Deploy the airbag.
(1) Check that no one is inside the vehicle or within a
10 m (33 ft) radius of the vehicle.
(2) Press the SST activation switch and deploy the air-
bag.
CAUTION:

When deploying the airbag, make sure that no one is
near the vehicle.

The front passenger airbag assembly becomes ex-
tremely hot when the airbag is deployed, so do not
touch it for at least 30 minutes after deployment.

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

Do not apply water, etc. to a front passenger airbag
assembly with a deployed airbag.

Always wash your hands with water after completing
the operation.
HINT:
The airbag deploys as the LED of the SST activation switch
comes on.
2. DEPLOYMENT WHEN DISPOSING OF FRONT PAS-
SENGER AIRBAG ASSEMBLY ONLY
NOTICE:

When disposing of the front passenger airbag assem-
bly, never use the customer's vehicle to deploy the
airbag.

Be sure to follow the procedure detailed below when
deploying the airbag.
HINT:
Prepare a battery as the power source to deploy the airbag.
(a) Check the function of the SST (see step 1±(a)).
(b) Remove the front passenger airbag assembly (see page
RS±33).
CAUTION:

When removing the front passenger airbag assembly,
work must be started 90 seconds after the ignition
switch is turned to the ºLOCKº position and the nega-
tive (±) terminal cable is disconnected from the bat-
tery.

When storing the front passenger airbag assembly,
keep the airbag deployment side facing upward.

(c) Using a service±purpose wire harness for the vehicle, tie
down the front passenger airbag assembly to the tire.
Wire harness: Stripped wire harness section
1.25 mm
2
or more (0.0019 in.2 or more)
CAUTION:
If the wire harness is too thin or an alternative object is
used to tie down the front passenger airbag assy, it may be
snapped by the shock when the airbag is deployed. Always
use a wire harness for vehicle use with an area of at least
1.25 mm
2
(0.0019 in.2).
HINT:
To calculate the area of the stripped wire harness section:
Area = 3.14 X (Diameter)
2 divided by 4
(1) Position the front passenger airbag assembly in-
side the tire with the airbag deployment side facing
inside.
Tire size: Must exceed the following dimensions:
Width: 185 mm (7.28 in.)
Inner diameter: 360 mm (14.17 in.)
CAUTION:

Make sure that the wire harness is tight. If there is
slack in wire harness, the front passenger airbag as-
sembly may become loose due to the shock when the
airbag is deployed.

Always tie down the front passenger airbag assembly
with the airbag deployment side facing inside.
NOTICE:
The tire will be marked by the airbag deployment, so use an
extra tire.
