INSPECTION

1.

VEHICLE NOT INVOLVED IN COLLISION

(a)

Perform a diagnostic system check  (see page 

DI–1147

).

(b)

With the steering wheel pad installed on the vehicle, per-
form a visual check. If there are any defects as mentioned
below, replace the steering wheel pad with a new one:
Cuts, minute cracks or marked discoloration on the steer-
ing wheel pad top surface or in the grooved portion.

2.

VEHICLE INVOLVED IN A COLLISION AND AIRBAG IS
NOT DEPLOYED

(a)

Perform a diagnostic system check (see page 

DI–1147

).

(b)

With the steering wheel pad removed from the vehicle,
perform a visual check. If there are any defects as men-
tioned below, replace the steering wheel pad or steering
wheel assembly with a new one:

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

Cracks or other damage to the connectors.

Deformation of the steering wheel assembly.

Deformation of the horn button contact plate of the horn
button assembly.

There should be no interference between the steering
wheel pad and steering wheel assembly, and the clear-
ance should be uniform all the way around when a new
steering wheel pad is installed on the steering wheel as-
sembly.

CAUTION:
For removal and installation procedures of the steering
wheel pad, see page 

RS–21

 and 

RS–31

. Be sure to follow

the correct procedure.

DISPOSAL

HINT:
When scrapping a vehicle equipped with SRS or disposing of
the steering wheel pad, be sure to deploy the airbag first in ac-
cordance with the procedure described below. If any abnormal-
ity occurs with the airbag deployment, contact the SERVICE
DEPT. of TOYOTA MOTOR SALES, USA, INC.
CAUTION:

Never dispose of a steering wheel pad which 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 an airbag, perform the operation at
least 10 m (33 ft) away from the steering wheel pad.

The steering wheel pad becomes extremely 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 steer-
ing wheel pad with the deployed airbag.

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

Always wash your hands with water after completing
the operation.

HICLE

HINT:
Prepare a battery as the power source to deploy the airbag.

(a)

Check the function of the SST.

(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.

(2)

Check the function of the SST.
Press the SST activation switch, and check that the
LED of the SST activation switch comes on.

CAUTION:

Do not connect the SST connector (yellow colored
one) to the airbag.

If the LED comes on when the activation switch is not
being pressed, SST malfunction is possible, so re-
place the SST with a new one.
(3)

Disconnect the SST from the battery.

(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 steering column cover lower.
(1)

While turning the steering wheel assembly to the
right and left, remove the 3 screws and steering col-
umn cover lower.

(e)

Install the SST.

CAUTION:
Check that there is no looseness in the steering wheel as-
sembly and steering wheel pad.

(1)

Disconnect the airbag connector (yellow colored
one) from the spiral cable.

NOTICE:
When handling the airbag connector, take care not to dam-
age the airbag wire harness.

NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock.

(3)

Move the SST at least 10 m (33 ft) away from the ve-
hicle front side window.

(4)

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.

(5)

Connect the red clip of the SST to the battery posi-
tive (+) terminal and the black clip of the SST to the
negative (–) terminal.

(f)

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 steering wheel pad becomes extremely 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 steer-
ing wheel pad with a deployed airbag.

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

the customer’s vehicle to deploy the airbag.

Be sure to follow the procedure given below when de-
ploying the airbag.

HINT:
Prepare a battery as the power source to deploy the airbag.
