AIR BAG MODULE AND SEAT BELT PRE-TENSIONER 

DISPOSAL PROCEDURES

M1524001200473

Before disposing of an air bag or a vehicle equipped with an air bag, follow the procedures below to deploy 
the air bag.

UNDEPLOYED AIR BAG MODULE DISPOSAL

Required Special Tools:

• MB686560: SRS Air Bag Adapter Harness

• MB991885: Pre-tensioner Adapter Harness (For pre-ten-

sioner)

AIR BAG MODULE AND SEAT BELT PRE-TENSIONER DISPOSAL PROCEDURES

TSB Revision

SUPPLEMENTAL RESTRAINT SYSTEM (SRS)

52B-388

WARNING

•

If the vehicle is to be scrapped or otherwise dis-
posed of, deploy the air bags and operate the seat 
belt pre-tensioners inside the vehicle. If the vehicle 
will continue to be used and only the air bag mod-
ules and seat belt pre-tensioner are to be disposed 
of, deploy the air bags and operate the seat belt 
pre-tensioners outside the vehicle.

•

Since a large amount of smoke is produced when 
the air bag is deployed and the seat belt pre-ten-
sioner is operated, avoid residential areas when-
ever possible.

•

Since there is a loud noise when the air bags are 
deployed and when the seat belt pre-tensioners 
are operated, avoid residential areas whenever 
possible. If anyone is nearby, give warning of the 
impending noise.

•

Suitable ear protection should be worn by person-
nel performing these procedures or by people in 
the immediate area.

.

DEPLOYMENT INSIDE THE VEHICLE (WHEN 
DISPOSING OF A VEHICLE) <AIR BAG MODULE 
(DRIVER'S SIDE)>

1. Move the vehicle to an isolated spot.

DANGER

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

P.52B-26

).

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 column cover lower (Refer to GROUP 52A, 

Instrument Panel 

P.52A-3

).

4. Remove the connection between the C-307 clock spring 

connector (four-pin) and the harness side connector 
(four-pin, yellow).

NOTE: If the clock spring connector is disconnected from 
the instrument panel wiring harness, both electrodes of the 
clock spring connector will be automatically shorted to pre-
vent unintended deployment of the air bag due to static elec-
tricity, etc.

5. Obtain two suitable wires, which are 6 meters (20 feet) or 

longer, as deployment wires. Then connect the wires at one 
end to short.

NOTE: This prevents the air bag from unintentional deploy-
ment caused by static electricity, etc.

CAUTION

Never fail to do Step 6 in order to prevent accidental 
deployment caused by static.
6. Touch the vehicle’s body with your bare hands to discharge 

static electricity.

7. Cut the instrument panel wiring harness (four-pin, yellow) 

shown in the figure, while the C-307 clock spring connector 
(four-pin) is disconnected.

NOTE: The disconnection location should be sufficiently 
away from the C-307 harness side connector with consider-
ation to the expansion harness connection location upon 
disconnection.

8. Individually connect a harness to the four disconnected 

harnesses, cover the connection areas with insulation tape, 
and then pull out the expansion harness outside the vehicle.

9. Connect the C-307 harness side connector connected with 

the expansion harness to the C-307 clock spring connector.

WARNING

If the windshield glass is scratched, air bag deploy-
ment could cause it to crack and fly out of the vehicle, 
so always put a cover over the vehicle.

10.To suppress the sound as much as possible, completely 

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

WARNING

•

Before deploying the air bag 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 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 
the air bag deployment. See Deployed Air Bag 
Module and Operated Seat Belt Pre-tensioner Dis-
posal (Refer to 

P.52B-403

) for post-deployment 

handling instructions.

•

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

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

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.

12.After deployment, dispose of the air bag module according 

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

P.52B-403

).
