(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.

TROUBLESHOOTING
PROBLEM SYMPTOMS TABLE
Use the table below to help you find the cause of the problem. The numbers \
indicate the priority of the likely
cause of the problem. Check each part in order. If necessary, replace these parts.
(w/ Differential locking system):
Check that center differential lock mode is set.
When switching differential Free↔Lock, the indicator lamp will blink if the gears of the differen-
tial lock sleeve are not meshed. If this occurs, when the tires are rotated \
to apply differential
power to the differential, the differential locks and the indicator lamp\
light up.

(b) Ensure that the matchmarks of the pinion of the actuator
is in the extent between zero and 5 degrees clockwise
above the center line of the actuator.
If the matchmarks is not in this extent, rotate the pinion to be
matched. Do not supply the battery positive voltage directly be-
tween terminals. If the matchmarks come to the extension limit
of the rotation, do not electrify moreover.
(c) Install a new O−ring to the actuator.
(d) Apply a light coat of gear oil on the O −ring.
(e) Apply MP grease to the gear part.
(f) Insert the actuator so that the long hole on the actuator side fits with the knock pin on the carrier side.
HINT:
Do not damage the O −ring of the actuator.
(g) Align the actuator with the long hole and rotate the actua-
tor counterclockwise when the knock pin reaches the
right−hand side.
(h) Install the actuator to the differential carrier with the bolt so that the outermost rack tooth of the shift fork will fit the
matchmarks of the pinion of the actuator.

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.

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.
