(e) 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) When scrapping a vehicle, deploy the airbag and scrap the vehicle with the front passenger airbag
assembly still installed.
(2) When moving a vehicle for scrapping which has a front passenger airbag assembly with deployed air-
bag, use gloves and safety glasses.
2. DEPLOYMENT WHEN DISPOSING OF FRONT PAS- SENGER AIRBAG ASSEMBLY ONLY
NOTICE:
When disposing of the front passenger airbag assem-
bly only, never use the customer’s vehicle to deploy
the airbag.
Be sure to follow the procedure given below when de-
ploying the airbag.
HINT:
Have a battery ready as the power source to deploy the airbag.
(a) Remove the front passenger airbag assembly. (See page RS−22 )
CAUTION:
When removing the front passenger airbag assembly,
work must be started 90 seconds after the ignition
switch is turned to the ”LOCK” position and the nega-
tive (−) terminal cable is disconnected from the bat-
tery.
Store the front passenger airbag assembly with the
airbag deployment side facing upward.
(b) Using a service− purpose wire harness for the vehicle, tie
down the front passenger airbag assembly to the tire.

(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.

(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.

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.
