SRS AIRBAG
PRECAUTION
CAUTION:

The LAND CRUISER is equipped with SRS, which comprises a driver airbag, front passenger
airbag, side airbag and curtain shield airbag. Failure to carry out service operations in the cor-
rect sequence could cause the SRS to unexpectedly deploy during servicing, possibly leading
to a serious accident. Further, if a mistake is made in servicing the SRS, it is possible that the
SRS may fail to operate when required. Before performing servicing (including removal or
installation of parts, inspection or replacement), be sure to read the following items carefully,
then follow the correct procedures described in the repair manual.

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.
(The SRS is equipped with a back-up power source so that if work is started within 90 seconds
from disconnecting the negative (-) terminal cable of the battery, the SRS may be deployed.)

Do not expose the steering wheel pad, front passenger airbag assembly, side airbag assembly,
curtain shield airbag assembly, airbag sensor assembly, front airbag sensor, side and curtain
shield airbag sensor assembly, curtain shield airbag sensor assembly or seat position sensor
assembly directly to hot air or flames.
NOTICE:

Malfunction symptoms of the SRS are difficult to confirm, so the DTCs become the most impor-
tant source of information when troubleshooting. When troubleshooting the SRS, always in-
spect the DTCs before disconnecting the battery.

Even in the case of a minor collision where the SRS does not deploy, the steering wheel pad,
front passenger airbag assembly, side airbag assembly, curtain shield airbag assembly, airbag
sensor assembly, front airbag sensor, side and curtain shield airbag sensor assembly, curtain
shield airbag sensor assembly and seat position sensor assembly should be inspected (See
page RS-18, RS-32, RS-47, RS-60, RS-71, RS-76, RS-81, RS-87 and RS-92).

Before repairs, remove the airbag sensor if shocks are likely to be applied to the sensor during
repairs.

Never use SRS parts from another vehicle. When replacing parts, replace them with new parts.

Never disassemble and repair the steering wheel pad, front passenger airbag assembly, side
airbag assembly, curtain shield airbag assembly, airbag sensor assembly, front airbag sensor,
side and curtain shield airbag sensor assembly, curtain shield airbag sensor assembly or seat
position sensor assembly in order to reuse it.

If the steering wheel pad, front passenger airbag assembly, side airbag assembly, curtain
shield airbag assembly, airbag sensor assembly, front airbag sensor, side and curtain shield
airbag sensor assembly, curtain shield airbag sensor assembly or seat position sensor assem-
bly has been dropped, or if there are cracks, dents or other defects in the case, bracket or con-
nector, replace it with new one.

Use a volt/ohmmeter with high impedance (10 kW/V minimum) for troubleshooting the system's
electrical circuits.

Information labels are attached to the periphery of the SRS components. Follow the instruc-
tions on the notice.

After work on the SRS is completed, perform the SRS warning light check (See page DI-692).

HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Remove the steering wheel pad (See page SR-14).
CAUTION:

When storing the steering wheel pad, keep the upper
surface of the pad facing upward.

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.
(b) 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 a wire harness which is too thin or some other thing is
used to tie down the steering wheel pad, it may be snapped
by the shock when the airbag is deployed. This is highly
dangerous. Always use a wire harness for vehicle use
which is at least 1.25 mm
2
(0.0019 in2).
HINT:
To calculate the square of the stripped wire harness section:
Square = 3.14 x (Diameter)

divided by 4
(1) Install the 2 bolts with washers in the 2 bolt holes in
the steering wheel pad.
Bolt:
L: 35.0 mm (1.387 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) Connect the connectors of the SST to the steering
wheel pad connectors.
