(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.

SUPPLEMENTAL RESTRAINT SYSTEM STEERING WHEEL PAD AND SPIRAL CABLE
RS−11
1996 LAND CRUISER (RM451U)
DISPOSAL
HINT:
When scrapping vehicle equipped with an SRS or disposing of
a steering wheel pad (with airbag), always first deploy the air-
bag 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.
When disposing of a steering wheel pad with an airbag
deployed in a collision, follow the same procedure given in step
1−(d) in ”DISPOSAL”.
CAUTION:
Never dispose of a steering wheel pad which has an
undeployed airbag.
The airbag produces a sizeable exploding sound
when it deploys, so perform the operation out of
doors and where it will not create a nuisance to
nearby residents.
When deploying the airbag, always use the specified
SST (SRS Airbag Deployment Tool). Perform the op-
eration in a place away from electrical noise.
SST 09082−00700
When deploying an airbag, perform the operation at
least 10 m (33 ft) away from the steering wheel pad.
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 the deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a steering wheel pad with
the deployed airbag.

DISPOSAL
HINT:
When scrapping vehicle equipped with an SRS or disposing of
a front passenger airbag assembly, always first deploy the air-
bag in accordance with the procedure described below. If any
abnormality occurs with the airbag deployment, contact the
SERVICE DEPT. of TOYOTA MOTOR SALES, U.S.A., INC.
When disposing of a front passenger airbag assembly with an
airbag deployed in a collision, follow the same procedure given
in step 1−(e) in ”DISPOSAL”.
CAUTION:
Never dispose of a front passenger airbag assembly
which has an undeployed airbag.

When deploying an airbag, perform the operation at
least 10 m (33 ft) away from the front passenger air-
bag assembly.
The front passenger airbag assembly is very hot
when the airbag is deployed, so leave it alone for at
least 30 minutes after deployment.
Use gloves and safety glasses when handling a front
passenger airbag assembly with deployed airbag.
Always wash your hands with water after completing
the operation.
Do not apply water, etc. to a front passenger airbag
assembly with deployed airbag.

REASSEMBLY
1. w/o DIFFERENTIAL LOCK: ASSEMBLE DIFFERENTIAL CASE
(a) Apply all of the sliding and rotating sufaces with gear oil.
(b) Install the 2 thrust washers and side gears. Using the table below, select the thrust washers which will
ensure that the backlash is within the specification.
Try to select washers of the same size for both sides.
Thrust washer thickness
Thickness mm (in.)Thickness mm (in.)
1.60 (0.063).80 (0.071)
1.70 (0.067)1−
(c) Install the 2 side gears with the side gears thrust washers,
4 pinion gears, pinion gear thrust washers and pinion
shaft.
HINT:
Align the hole for the pinion shaft with the case hole.
(d) Using a dial indicator, measure the side gear backlash with holding one pinion gear toward the case.
Backlash: 0.05 − 0.20 mm (0.0020 − 0.0079 in.)
If the backlash is not within the specification, install a thrust
washer of different thickness.
(e) Using a pin punch and hammer, install the straight pin through the holes in the dif ferential case and pinion shaft.
(f) Using a chisel and hammer, stake the out side of the dif- ferential case pin hole.
2. w/ DIFFERENTIAL LOCK: INSPECT SLEEVE
