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.

(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.

(a) Check the function of the SST (see step 1±(a)).
(b) Remove the steering wheel pad (see page SR±14).
CAUTION:

When removing the steering wheel pad, work must be
started 90 seconds after the ignition switch is turned
to the ºLOCKº position and the negative (±) terminal
cable is disconnected from the battery.

When storing the steering wheel pad, keep the airbag
deployment side facing upward.
(c) Using a service±purpose wire harness for the vehicle, tie
down the steering wheel pad to the disc wheel.

or more (0.0019 in2. or more).
CAUTION:
If the wire harness is too thin or an alternative object is
used to tie down the steering wheel pad, 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)

(1) Install the 2 bolts with washers into the 2 bolt holes
on the steering wheel pad.
Bolt:
L: 35.0 mm (1.378 in.)
M: 6.0 mm (0.236 in.)
Pitch: 1.0 mm (0.039 in.)
NOTICE:

Tighten the bolts by hand until the bolts become diffi-
cult to turn.

Do not tighten the bolts excessively.
(2) After connecting the SST below to each other, con-
nect them to the steering wheel pad connectors.
