AIR BAG MODULE AND SEAT BELT PRE-TENSIONER DISPOSAL PROCEDURES
TSB Revision
SUPPLEMENTAL RESTRAINT SYSTEM (SRS)
52B-417
AIR BAG MODULE AND SEAT BELT PRE-TENSIONER
DISPOSAL PROCEDURES
M1524001201573
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:
• MB992102: Air Bag Inflation Adapter Harness
• MB991885: Adapter Harness
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) <DRIVER'S AIR BAG
MODULE>
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
).
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 cover (Refer to

4. Slide the outer housing of the driver’s air bag module
connector in the arrow direction shown, and disconnect the
connector.
NOTE: When the driver's air bag module connector is dis-
connected from the inflator, the four pins of inflator connec-
tor are automatically shorted. This prevents the
unintentional deployment of driver's air bags caused by the
static or others.
5. Connect deployment wires, each 6 meters (20 feet) or
longer, to the two leads of special tool MB992102, and cover
the connections with insulator tape. The other ends of the
deployment wires should be connected to each other
(short-circuited), to prevent sudden unexpected deployment
of the air bag module.
NOTE: This prevents the air bags from being unintentionally
deployed because of the static and others.
6. Connect the special tool MB992102 to the driver's air bag
module, and then pull out the deployment wire to outside the
vehicle.
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.
7. To suppress the sound as much as possible, completely
close all door windows, close the doors and put a cover on
the vehicle.
