AIR BAG MODULE AND SEAT BELT PRE-TENSIONER DISPOSAL PROCEDURES
Before disposing of a vehicle which is equipped with air bags or seat belts with pre-tensioner, or when disposing of the air bags or seat belt pre-tensioner themselves, the following procedures must be used to deploy the air bags or operate the seat belt pretensioner before disposal.

UNDEPLOYED AIR BAG MODULE AND SEAT BELT PRE-TENSIONER DISPOSAL

Required Special Tools:
MB628919 or MR203491: SRS Air bag adapter harness B
MB686560: SRS air bag adapter harness A

WARNING:
- If the vehicle is to be scrapped or otherwise disposed of, deploy the air bags and operate the seat belt pre-tensioner inside the vehicle. If the vehicle will continue to be used and only the air bag modules and seat belt pre-tensioner are to be disposed of, deploy the air bags and operate the seat belt pre-tensioner outside the vehicle.
- Since a large amount of smoke is produced when the air bag is deployed and the seat belt pre-tensioner is operated, avoid residential areas whenever possible.
- Since there is loud noise when the air bags are deployed and when the seat belt pre-tensioner are operated, avoid residential areas whenever possible. If anyone is nearby, give warning of the impending noise.
- Suitable ear protection should be worn by personnel performing these procedures or by people in the immediate area.

DEPLOYMENT INSIDE THE VEHICLE (when disposing of a vehicle)
1. Move the vehicle to an isolated spot.

DANGER: Wait at least 60 seconds after disconnecting the battery cables before doing any further work.

2. Disconnect the negative (-) and positive (+) battery cables from the battery terminals, and then remove the battery from the vehicle.




3. To deploy the air bag module (driver's side):
1. Remove the steering column cover lower.
2. Remove the connection between the clock spring two-pin connector (red) and the body wiring harness connector.

NOTE: If the clock spring connector is disconnected from the body wiring harness, both electrodes of the clock spring connector will be automatically shorted to prevent unintended deployment of the air bag due to static electricity etc.




4. To deploy the air bag module (front passenger's side):
1. Loosen the stopper to remove the glove box.
2. Remove the connection between the air bag module (front passenger's side) connector (red two-pin) and the body wiring harness connector.




5. To operate the seat belt pre-tensioner:
1. Remove the center pillar trim, lower.
2. Remove the connection between the seat belt pre-tensioner two-pin connector (red) and the floor wiring harness connector (two-pin, red).

NOTE: If the seat belt pre-tensioner connector is disconnected 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.




6. Connect deployment wires, each 6 meters (20 feet) or longer, to the two leads of special tool MB686560 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 deployment of the air bag and operate the seat belt pre-tensioner.




7. Connect the clock spring or air bag module (front passenger's side) or seat belt pre-tensioner two-pin connector (red) to special tool MB686560 and move the deployment wires out of the vehicle.

WARNING: If the glass is scratched, air bag deployment or seat belt pre-tensioner operation could cause it to crack and fly out of the vehicle, so always put a cover over the vehicle.




8. To suppress the operation sound as much as possible completely close all door windows, close the door and put the cover on the vehicle.

WARNING:
- Before deploying the air bag and 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.
- After the air bag has been deployed or the seat belt pre-tensioner has been triggered, the inflator is very hot. So wait for at least thirty minutes before the inflator is handled. See Deployed Air Bag Module and Seat Belt pre-tensioner Disposal Procedures for post-deployment handling instructions.
- Just in case that the air bag module could not been deployed or the seat belt pre-tensioner could not been operated, contact the MMSA Tech Line.

9. 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 and operating the seat belt pre-tensioner.
10. For the disposal of an deployed air bag module or seat belt pre-tensioner, see the Deployed Air Bag Module Disposal Procedures.
