Driver Air Bag Module
Before either disposing of a vehicle equipped with an air bag, or prior to disposing of the air bag module, be sure to first follow the procedures described below to and deploy the air bag.CAUTION:
a. If the vehicle is to be scrapped, junked, or otherwise disposed of, deploy the air bag inside the vehicle. If the vehicle will continue to be operated and only the air bag module is to be disposed of, deploy the air bag outside the vehicle.
b. Since a large amount of smoke is produced when the air bag is deployed, select a well-ventilated site. Moreover, never attempt the test near a smoke sensor.
c. Since there is a loud noise when the air bag is deployed, avoid residential areas whenever possible. If anyone is nearby, give warning of the impending noise.
d. Suitable ear protection should be worn by personnel performing these procedures or by people in the immediate area.
DEPLOYMENT OUTSIDE THE VEHICLE
CAUTION:
a. This operation should be done at a spacious and flat place where there is no people and obstacle around within a radius of more than 6 m (20 feet).
b. Do not perform deployment outside, if a strong wind is blowing, and if there is even a slight breeze, the air bag module should be placed and deployed 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: Wait at least 60 seconds after disconnecting the battery cables before doing any further work. The SRS system is designed to retain enough voltage to deploy the air bag even after the battery has been disconnected. Serious injury may result from unintended air bag deployment if work is done on the SRS system immediately after the battery cables are disconnected.
2. Remove the air bag module from the vehicle.
CAUTION: Store the air bag module on a flat surface with the pad cover facing up. Do not place anything on top of it.
3. Connect two wires each 6 meters (20 feet) long or more, to the two leads of SRS AIR BAG ADAPTER HARNESS B, and cover the connections with insulation tape. The other ends of the two wires should be connected to each other (short-circuited), to prevent sudden unexpected deployment of the air bag.
4. Pass SRS air bag adapter harness B, connected with wires, under the used tire wheel assembly and connect the harness to the air bag module.
5. Put the air bag module in the used wheel. Using the wires or the like connected to the module's bolts, secure the air bag module to the wheel. Then place the wheel with the module facing upward.
CAUTION: Slacken the adapter harness under the wheel to allow for the reaction produced in deployment of the module. If not, the adapter harness may be damaged by the reaction created in deployment.
6. Stick three used tires without wheel, on the tire to which the air bag module has been secured.
7. At a location as far away from the air bag module as possible, and from a shielded position, if possible, disconnect the two connected wires from each other and connect them to the two terminals of the battery (removed from the vehicle) to deploy the air bag.
CAUTION:
a. Before deployment, check carefully to be sure that no one is nearby, because deployment will cause the air bag module to jump upward about 1.5 to 3 meters (about 5 to 10 feet) into the air.
b. The inflator will be quite hot immediately following deployment, so wait at least 30 minutes to allow it to cool before attempting to handle it.
c. Although not poisonous, do not inhale gas from air bag deployment. See Deployed Air Bag Module Disposal Procedures for post-deployment handling instructions.
d. If the air bag module fails to deploy, do not go near the module. Contact the MMSA Tech Line.
