Deployment Outside the Vehicle
AIR BAG MODULE AND SEAT BELT PRE-TENSIONER DISPOSAL PROCEDURESBefore 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 OUTSIDE THE VEHICLE
WARNING:
- Deploy the air bag or operate the seat belt pre-tensioner in a wide, flat area at least 6 m (20 feet) away from obstacles and other people.
- Do not perform deployment or operation outside if a strong wind is blowing. If there is a slight breeze, place the air bag module or seat belt pre-tensioner downwind from the battery
DANGER: Wait at least 60 seconds after disconnecting the battery cables before doing any further work.
1. Disconnect the negative (-) and positive (+) battery cables from the battery terminals, and then remove the battery from the vehicle.
WARNING: Store the deployed air bag module or seat belt pretensioner the correct way up with its padded surface or its operation surface uppermost on a fiat surface. Do not place anything on top of them.
2. Remove the air bag module and seat belt with pre-tensioner from the vehicle.
3. Connect deployment wires, each 6 meters (20 feet) or longer, to the two leads of special tool MB628919 or MR203491 (driver's side) or special tool MB686560
4. Prepare the air bag modules and seat belt pre-tensioner as follows:
1. Air bag module (driver's side)
a. Take special tool MB628919 or MR203491 that is connected to the deployment wires, pass it beneath an old tire wheel assembly, and connect it to the air bag module.
CAUTION: The adapter harness below the wheel should be loose. If it is too tight, the reaction when the air bag deploys could damage the adapter harness.
b. Pass the thick wire through the air bag module mounting hole, and then secure the air bag module to an old tire with a wheel in it so that the pad on the module is facing upwards.
c. Place three old tires without wheels on top of the tire secured to the air bag module.
2. Air bag module (font passenger's side)
a. Connect the deployment wires to special tool MB686560, pass it beneath the tire and wheel assembly, and connect it to the air bag module.
CAUTION:
- The adapter harness below the wheel should be loose. If it is too tight, the reaction when the air bag deploys could damage the adapter harness.
- During deployment, the connector of special tool MB686560 must not be between the tires.
b. Pass the thick wires into the hole of the air bag module bracket, and secure it to the wheel of the old tire with wheel (four locations), with the air bag facing upwards.
c. Place three old tires without wheels on top of the tire secured to the air bag module, and secure all tires together with ropes (four locations).
3. Seat belt pre-tensioner
a. Connect special tool MB686560, which the deployment wires is attached to, to the seat belt pre-tensioner connector.
CAUTION: The adapter harness below the wheel should be loose. If it is too tight, the reaction when the air bag deploys could damage the adapter harness.
b. Pass the thick wires through the hole on the seat belt pre-tensioner bracket and secure them to the front (raised part) of the wheel on two places.
c. Pull the seat belt out the outside of the tire, and then place one tire without a wheel inside on top of the existing tire.
WARNING:
- Before deployment and operation, check carefully to be sure that no one is nearby.
- 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.
5. 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 bee removed from the vehicle) to deploy the air bag and operate the seat belt pre-tensioner.
6. For the disposal of an deployed air bag module or seat belt pre-tensioner, see the Deployed Air Bag Module Disposal Procedures.
