AIR BAG MODULE AND SEAT BELT PRE-TENSIONER DISPOSAL PROCEDURES

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-260

DANGER

Wait at least 60 seconds after disconnecting the bat-
tery cables before doing any further work (Refer to 

P.52B-16

).

WARNING

Battery posts, terminals and related accessories con-
tain lead and lead compounds. WASH HANDS AFTER 
HANDLING.

2. Disconnect the negative (

−) and positive (+) battery cables 

from the battery terminals, and then remove the battery from 
the vehicle.

3. Remove the center pillar lower trim (Refer to GROUP 52A, 

TRIMS 

P.52A-11

).

4. Execute the following steps to disconnect D-21 or D-33 seat 

belt pre-tensioner connector (two-pin) from the harness side 
connector (two-pin, black).

NOTE: If the seat belt pre-tensioner connector is discon-
nected from the floor wiring harness, both electrodes of the 
seat belt pre-tensioner connector will be automatically 
shorted to prevent unintended operation of the seat belt 
pre-tensioner due to static electricity, etc.

(1) Use a flat-tip screwdriver to unlock the harness side 

connector (two-pin, black) locking button by withdrawing 
it toward you in two stages.

(2) Disconnect the D-21 or D-33 harness side connector.

5. Connect deployment wires, each 6 meters (20 feet) or 

longer, to the two leads of special tool pre-tensioner adapter 
harness (MB991885), and cover the connections with 
insulation tape. The other ends of the deployment wires 
should be connected to each other (short-circuited), to 
prevent sudden unexpected operation of the seat belt 
pre-tensioner.

6. Connect the D-21 or D-33 seat belt pre-tensioner two-pin 

connector (black) to special tool pre-tensioner adapter 
harness (MB991885), and move the deployment wires out of 
the vehicle.

WARNING

If the glass is scratched, seat belt pre-tensioner oper-
ation could cause it to crack and fly out of the vehicle, 
so always put a cover over the vehicle.

7. To suppress the operation sound as much as possible 

completely close all door windows, close the doors and put 
the cover on the vehicle.

WARNING

•

Before operating the seat belt pre-tensioner in this 
manner, first check to be sure that there is no one 
in or near the vehicle. Wear safety glasses.

•

The inflator will be quite hot immediately following 
the operation, so wait at least 30 minutes to allow 
it to cool before attempting to handle it. Although 
not poisonous, do not inhale gas from the seat belt 
pre-tensioner operation. See Deployed Air Bag and 
Operated Seat Belt pre-tensioner Disposal (Refer 
to 

P.52B-269

) for post-operation handling instruc-

tions.

•

If the seat belt pre-tensioner fails to operate, do 
not go near the seat belt pre-tensioner.

8. At a location as far away from the vehicle as possible, 

disconnect the two connected wires from each the, and 
connect them to the two terminals of the battery (which has 
been removed from the vehicle) to operate the seat belt 
pre-tensioner.

9. After operation, dispose of the seat belt pre-tensioner 

according to the Deployed Air Bag Module operated seat 
belt pre-tensioner Disposal (Refer to 

P.52B-269

).

.

DEPLOYMENT OUTSIDE THE VEHICLE <AIR BAG 
MODULE (DRIVER'S SIDE)>

DANGER

Wait at least 60 seconds after disconnecting the bat-
tery cables before doing any further work (Refer to 

P.52B-16

).

WARNING

•

Battery posts, terminals and related accessories 
contain lead and lead compounds. WASH HANDS 
AFTER HANDLING.

•

Deploy the air bag in a wide, flat area at least 6 
meters (20 feet) away from obstacles and other 
people.

•

Do not perform deployment outside if a strong 
wind is blowing. If there is a slight breeze, place 
the air bag module downwind from the battery.

1. Disconnect the negative (

−) and positive (+) battery cables 

from the battery terminals, and then remove the battery from 
the vehicle.

CAUTION

Once disconnected, both electrodes of the driver’s air bag 
module connector short automatically to prevent acciden-
tal deployment caused by static etc. Still, in consideration 
of the accidental deployment, store the air bag module on 
a flat place with deployment surface facing up. Do not put 
anything on it.
2. Remove the air bag module from the vehicle (Refer to 

P.52B-237

).

3. Prepare two wires longer than 6 meters (20 feet) for 

deployment and connect the terminals in one end to 
short-circuit. This is to prevent accidental deployment 
caused by static etc.

CAUTION

Never fail to do Step 4 in order to prevent accidental 
deployment caused by static.
4. Touch the vehicle’s body with your bare hands to discharge 

static electricity.

5. Using pliers, cut the driver’s air bag module connector from 

the harnesses. Connect the deployment wires to each 
harness that has been cut and insulate the connections with 
plastic tape.

6. Install a nut to the bolt behind the driver’s air bag module 

and tie thick wire there for securing.

7. Route the deployment wires connected to the driver’s air 

bag module beneath an old tyre and wheel assembly. Then, 
using the wire tied to the bolt, secure the driver’s air bag 
module to the tyre and wheel assembly with the deployment 
surface facing up.

8. Place three old tyres without wheels on the tyre secured with 

the driver’s air bag module.

no one is nearby.

•

The inflator will be quite hot immediately following 
the deployment, so wait at least 30 minutes to 
allow it to cool before attempting to handle it. 
Although not poisonous, do not inhale gas from 
air bag deployment. See Deployed Air Bag Module 
and Operated Seat Belt Pre-tensioner Disposal 
(Refer to 

P.52B-269

) for post-deployment handling 

instructions.

•

If the air bag fails to deploy, do not go near the 
module.

9. At a location as far away from the air bag module as 

possible, and from a shielded position, disconnect the two 
connected wires from each other, and connect them, to the 
two terminals of the battery (which has been removed from 
the vehicle) to deploy the air bag.

10.Discard the deployed air bag module as specified in 

Deployed Air Bag Module and Operated Seat Belt 
Pre-tensioner Disposal (Refer to
