(f) Cover the steering wheel pad with a cardboard box or
tires.
Covering method using a cardboard box:
Cover the steering wheel pad with the cardboard
box and weight the cardboard box down in 4 places
with at least 190 N (20 kg, 44 lb).
Size of cardboard box:
Must exceed the following dimensions:
x=460 mm (18.11 in.)
When dimension of the cardboard box exceeds the di-
ameter of the disc wheel with tire to which the steer-
ing wheel pad is tied
x=460 mm (18.11 in.) + width of tire
y= 650 mm (25.59 in.)
NOTICE:
If a cardboard box smaller than the specified size is used,
the cardboard box will be broken by the shock from the air-
bag deployment.
Covering method using tires:
Place at least 3 ti res without disc wheel on top of the
disc wheel with tire to which the steering wheel pad
is tied.
Tire size: Must exceed the following dimensions −
Width: 185 mm (7.87 in.)
Inner diameter: 360 mm (14.17 in.)
CAUTION:
Do not use tires with disc wheels.
NOTICE:
The tires may be marked by the airbag deployment, so use
the redundant tires.
(g) Deploy the airbag. (1) Connect the SST red clip to the battery positive (+)
terminal and the black clip to the battery negative
(−) terminal.
(2) Check that no one is within 10 m (33 ft) area around
the disc wheel which the steering wheel pad is tied
to.
(3) Press the SST activation switch and deploy the air- bag.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.

SUPPLEMENTAL RESTRAINT SYSTEM FRONT PASSENGER AIRBAG ASSEMBLY
1996 LAND CRUISER (RM451U)
1. AIRBAG DEPLOYMENT WHEN SCRAPPING VE-
HICLE
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Check functioning of the SST. (See page RS−11 )
(b) Disconnect the airbag connector. (1) Remove the glove compartment door.
(2) Remove the No.1 under cover.
NOTICE:
When handling the airbag connector , take care not to dam-
age the airbag wire harness.
(3) Pull up the connector.
(4) Disconnect the airbag connector.
(c) Install the SST. (1) Connect the SST connector to the front passengerairbag assembly connector.
SST 09082−00700
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock.
(2) Move the SST to at least 10 m (33 ft) away from the
front of the vehicle.
(3) Close all the doors and windows of the vehicle.
NOTICE:
Take care not to damage the SST wire harness.
(4) Connect the SST red clip to the battery positive (+)terminal and the black clip to the negative (+) termi-
nal.
(d) Deploy the airbag. (1) Confirm that no one is inside the vehicle or within 10
m (33 ft) area around the vehicle.
(2) Press the SST activation switch and deploy the air- bag.
HINT:

(3) Tie the tires together with 2 wire harnesses.
CAUTION:
Make sure that the wire harnesses are tight. It is very dan-
gerous if loose wire harnesses result in the tires coming
free due to the shock from the airbag deploying.
HINT:
Place the SST connector and wire harness inside tires. Provide
at least 1 m (3 ft) of slack for the wire harness.
(e) Install the SST. Connect the SST connector to the front passenger airbag
assembly connector.
SST 09082−00700
NOTICE:
To avoid damaging the SST connector and wire harness,
do not lock the secondary lock of the twin lock.
(f) Deploy the airbag (1) Connect the SST red clip to the battery positive (+)terminal and the black clip to the battery negative
(−) terminal.
(2) Confirm that no one is within 10 m (33 ft) area around the tire which the front passenger airbag as-
sembly is tied to.
(3) Press the SST activation switch and deploy the air-
bag.
HINT:
The airbag deploys simultaneously as the LED of the SST ac-
tivation switch lights up.
(g) Dispose of the front passenger airbag assembly.
CAUTION:
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.
(1) Remove the front passenger airbag assembly from
the tire.
(2) Place the front passenger airbag assembly in a vi- nyl bag, tie the end tightly and dispose of it in the
same way as other general parts disposal.

DIFFERENTIAL LOCKING SYSTEM
ON−VEHICLE INSPECTION
1. INSPECT DIFFERENTIAL LOCK SYSTEM
(a) Inspect the indicator lights.
Check that the indicator lights (front side and rear side)
light up for approx. 1 second when the ignition switch is
turned ON.
(b) Inspect the differential lock operation. (1) Jack up the vehicle then start the engine.
(2) Put the transfer shift lever on the L position.
(3) When the Diff. lock control switch is set to the RR
position, the indicator light (rear side) is turned on.
Differential lock is applied to the rear wheel at this
time.
HINT:
If the gears of the differential lock system are not meshed, the
indicator light remains blinking, so rotate the tires to mesh the
gear.
(4) When the Diff. lock control switch is at the OFF posi-
tion, the indicator light goes off.
Differential lock is released for the rear wheel at this
time.
(5) When the Diff. lock control switch is set to the FR/ RR position, the indicator lights (front side and rear
side) are turned on.
Differential lock is applied to both the front wheels
and rear wheels at this time.

(6) Check the voltage between the terminals of the Diff.
lock ECU when switching the Diff. lock control
switch with the speedometer, registering approx. 8
km/h (5 mph) or more.
(7) Check that the indicator lights blink when center Diff. lock release mode is set.
Diff. lock is released for both the front wheels and
rear wheels at this time.
(8) Return the Diff. lock control switch to OFF.
(9) Stop the engine and lower the vehicle.
2. INSPECT DIFF. LOCK SYSTEM CIRCUIT
(a) Inspect the system circuit with connector disconnected. Disconnect the connector from the Diff. lock ECU and in-
spect the connector on the wire harness side, as shown
in the chart.

HINT:
When a signal enters the ECU to LOCK the front dif ferential and
set the rear differential to FREE (when battery positive voltage
is inputted to terminal 6 (RF) of ECU and about 0 V is inputted
to terminal 12 (R)), or a signal to FREE both the front and rear
differentials, the indicator lights keep blinking until the ignition
switch is turned off (Fail−safe function).
If the circuit is not as specified, check and repair or replace the
trouble part shown in the table above.
(b) Inspect the battery positive voltage Battery positive voltage: 10 − 14.5 V
(c) Inspect the system circuit with connector connected (1) Turn the ignition switch to the ON position.
(2) Keep the center Diff. lock condition.
(3) Remove the Diff. lock ECU.
(4) Using a voltmeter, measure the voltage when thedifferential lock control switch is in the position, as
shown below.
