When discarding the air bag modules
or a vehicle with SRS air bags, be sure to deploy
the air bags in advance as specified in the service
procedure that follows.
|
|
1.Move the vehicle to flat
and isolated spot.
|
|
2.
caution |
Disconnect the battery cable
connection, and wait for
60 seconds or more before starting the
work.
|
Disconnect the (-) and (+) terminals of
battery cable, and then remove
the battery from the vehicle.
|
|
3.Remove the Steering column
lower cover (Refer to GROUP 37 -
Steering column
shaft assembly ).
|

|
4.Remove the connection
between the clock spring connector (4-pin) and the harness
side
connector (4-pin).
note |
Once disconnected from the
instrument panel wiring harness, both electrodes
of the clock
spring connector short automatically. This
prevents the driver’s air bag from
accidental
deployment caused by static, etc.
|
|

|
5.Obtain two suitable wires,
which are 6 m or longer, as deployment wires. Then connect
the wires at one end to short. 6.Touch the
vehicle’s body with bare hands to discharge static in
you.
|

|
7.Cut with a pliers, etc.
the instrument panel wiring harness shown in the figure of
the
instructions, while the clock spring connector is
disconnected.
note |
The disconnection location
should be sufficiently away from the harness
side connector with
consideration to the expansion harness
connection location upon
disconnections.
|
8.Connect the deployment wires on the two
instrument panel wiring harnesses disconnected,
cover the connection areas with insulator tape and then pull
out the deployment wires outside
the vehicle. 9.Connect the harness side connector
connected with an expansion harness to the clock
spring connector.

10.
warning |
If the glass is scratched, the
glass may be shattered at deployment. Therefore,
cover
with a vehicle cover to avoid danger.
|
In order to suppress the operation sound as much as
possible, fully close all the door
windows, close the doors, and then cover the vehicle with a
vehicle cover. 11.
caution |
- Make sure that no one
is present inside or near the vehicle
before deploying the air bag.
- Immediately after the air bag
deployment, the inflator is extremely
hot. Thus, before
handling, leave the inflator for 30
minutes or more to cool.
- If the air bag module does not deploy,
consult with your distributor.
|
Disconnect the deployment wire connection at a place
as far as possible from the vehicle.
Then, connect the wires to the removed vehicle battery to
deploy the air bag module. 12.Discard the deployed
air bag module according to the disposal procedures (Refer
to
).
|
|
1.Move the vehicle to flat
and isolated spot.
|
|
2.Disconnect the (-)
and (+) terminals of battery cable, and then
remove the battery from the vehicle.
|
|
3.Remove the
passenger’s (front) air bag module from the vehicle
(Refer to ).
|
![](../../../img/52/ACB04307AB00ENG.png)
|
4.Use the flat-tipped
screwdriver to pull out the locking button of floor harness
connector.
After releasing the lock, disconnect the
connector.
note |
When the passenger’s
(front) air bag module connector is disconnected
from the
inflator, the two pins of inflator connector are
automatically shorted. This prevents the
unintentional
deployment of passenger’s (front) air bags
caused by the static or others.
|
|
![](../../../img/52/AC103480AJ00ENG.png)
|
5.Connect the deployment
wires of 6 m or more to each of the two wiring harnesses of
special
tool adapter harness (MB991885), and cover the connection
areas with insulation tape. Keep the
other ends of deployment wires connected to each other
(shorted).
note |
This prevents the
unintentional activation of inflator caused by
the static or others.
|
6.Connect the adapter harness to the
passenger’s (front) air bag module.
|
![](../../../img/52/ACB04902AB00ENG.png)
|
7.Connect the adapter
harness to the passenger’s (front) air bag module, and
then
pull out the deployment wire to outside the
vehicle.
|

8.
warning |
If the glass is scratched, the
glass may be shattered at deployment. Therefore,
cover
with a vehicle cover to avoid danger.
|
In order to suppress the operation sound as much as
possible, fully close all the door
windows, close the doors, and then cover the vehicle with a
vehicle cover. 9.
caution |

connection, and wait for
60 seconds or more before starting the
work.
|
Disconnect the (-) and (+) terminals of
battery cable, and then remove
the battery from the vehicle.
|
|
2.
caution |
When the connector is
disconnected, the two pins of air
bag module are automatically shorted to prevent
the unintentional deployment caused by the
static
or others. However, in preparation for the
accidental deployment, store the air bag module
on
a flat place with the deployment surface facing
upward. Also, do not put anything on
it.
|
Remove the driver’s air bag module from the
vehicle (Refer to ).
|

|
3.Cut the part shown to
connect the adapter harness (Special tool: MB991885) to the
driver’s
airbag module connector.
|
![](../../../img/52/AC103480AJ00ENG.png)
|
4.Connect the deployment
wires of 6 m or more to each of the two wiring harnesses of
special
tool adapter harness (MB991885), and cover the connection
areas with insulation tape. Keep the
other ends of deployment wires connected to each other
(shorted).
note |
This prevents the
unintentional activation of inflator caused by
the static or others.
|
5.Connect the adapter harness to the
driver’s air bag module. 6.To the torx screw
installation hole located at the backside of air bag module,
tie
a thick wire for fixing the wheel.
|
![](../../../img/52/AC100482AC00ENG.png)
|
7.Pass the deployment wire
connected to the air bag module underneath the old tyre with
wheel. Then, fix the air bag module with deployment surface
facing upward using the wire which
is tied to the bolt.
|
![](../../../img/52/ACX00610AD00ENG.png)
|
8.Place three old tyres
without wheel onto the tyre to which the air bag module is
fixed.

the air bag module
before deploying the air bag.
- Immediately after the air bag
deployment, the inflator is extremely
hot. Thus, before
handling, leave the inflator for 30
minutes or more to cool.
- If the air bag module does not deploy,

as far as possible from the air bag
module. Then, connect the wires to the removed vehicle
battery to deploy the air bag module. 10.Discard
the deployed air bag module according to the disposal
procedures (Refer to
).
|
|
1.
caution |
Before starting the work, wait
for 60 seconds or more
after the disconnection of the battery cable.
(Refer to the item 5
of Service
Precautions.)
|
Disconnect the (-) and (+) terminals of
battery cable, and then remove
the battery from the vehicle.

the hole of air bag module bracket. Then, with the air bag
module
deployment surface facing upward, fix the module to the old
tyre with wheel.
|
![](../../../img/52/ACX00611AD00ENG.png)
|
6.Place three old tyres
without wheel onto the tyre to which the air bag module is
fixed.
Then, tie and fix all the tyres with rope (4
positions).
note |
The passenger’s (front)
air bag has a larger deployment volume than the
driver’s
air bag. Therefore, it is necessary to tie the
tyres with rope.

7.
caution |
- Make sure that no one is
present near the air bag module before
deploying the air bag.
- Immediately after the air bag
deployment, the inflator is extremely
hot. Thus, before
handling, leave the inflator for 30
minutes or more to cool.
- If the air bag module does not deploy,
consult with your distributor.
|
Disconnect the deployment wire connection at a place
as far as possible from the air bag
module. Then, connect the wires to the removed vehicle
battery to deploy the air bag module. 8.Discard
the deployed air bag module according to the disposal
procedures (Refer to
).
|
|
After deployment and operation, the
air bag module and seat belt pre-tensioner should
be disposed of in the same manner as any other scrap parts,
adhering to local laws and/or legislation.
Observe the following precautions during air bag or seat
belt pre-tensioner disposal:
|
|
1.Immediately after the air
bag deployment, the inflator is extremely hot. Thus, before
handling, leave the inflator for 30 minutes or more to
cool.
|
|
2.Do not pour water or oil
onto the deployed air bag module.
|
|
3.To the deployed air bag
module, substances that irritate eyes and skin may be
deposited.
Therefore, wear gloves and protective glasses when handling
the module. When the substance comes
in contact with eyes or skin, flush with a large amount of
water.
|
|
4.Place the air bag module
in the sturdy plastic bag, and seal the bag for
disposal.
|
|
5.After the work, be sure to
wash your hands with water.
