^
Wear safety glasses throughout the procedures.
^
Make sure the area around the inflator module is clear of all people and loose or flammable objects.
^
Short the deployment harness wires as instructed.
^
Connect the deployment harness to the inflator module before you connect it to the power source.
^
Connect the deployment harness to the lower source to immediately deploy the air bag.
Failure to follow the procedures in the order listed may result in personal injury.
NOTICE: When the air bag deploys, the inflatable restraint steering wheel module may Jump about 30 cm (1 foot) vertically. This is a normal reaction
of the inflatable restraint steering wheel module to the force of the rapid gas expansion in side the air bag.
Figure 23
NOTICE: The rapid gas expansion involved with deploying an air bag is very loud. Notify all people in the immediate area that you in tend to deploy
the inflatable restraint steering wheel module.
23. Connect the SIR Deployment Harness wires to the power source. This immediately deploys the inflatable restraint steering wheel module (Figure
24).
24. Use a vehicle battery when available, but always use a power source that complies to the following:
^
12 volts minimum
^
2 amps minimum
25. Disconnect the SIR Deployment Harness from the power source.
26. Short the SIR Deployment Harness leads together by fully seating one banana plug into the other (Figure 18).

27. In the unlikely event that the inflatable restraint steering wheel module did not deploy after following these procedures, proceed immediately with
Steps 33 through 36. If the inflatable restraint steering wheel module did deploy, proceed with Steps 28 through 32.
28. Put on a pair of shop gloves to protect your hands from possible heat and irritation when handling the deployed inflatable restraint steering wheel
module (Figure 25).
After the inflatable restraint steering wheel module has deployed, the surface of the air bag may contain a powdery residue. This powder consists
primarily of cornstarch (used to lubricate the bag as it inflates), and by-products of the chemical reaction. The deployment reaction produces sodium
hydroxide dust (similar to lye soap). The sodium hydroxide quickly reacts with the atmospheric moisture. This atmospheric moisture converts the sodium
hydroxide into sodium carbonate and sodium bicarbonate (baking soda). Therefore, you will probably find no sodium hydroxide present after the
deployment. Gloves and safety glasses are recommended, however, as a precaution. Gloves and safety glasses help to prevent possible irritation of the
skin or eyes.
CAUTION: Immediately following the deployment of an air bag, the metal surfaces of the inflator module are very hot. Do not place the
deployed inflator module near any flammable objects. Walt for about ten minutes before touching any metal surface of the inflator module.
Disregarding these precautions may cause fire or personal injury.
The metal canister and the area surrounding the inflatable restraint steering wheel module are very hot. Do not touch the metal areas of the inflatable
restraint steering wheel module for about ten minutes after deployment. If you must move the deployed inflatable restraint steering wheel module, use
caution. Always wear gloves and handle the inflatable restraint steering wheel module by the air bag or the vinyl trim (Figure 25).
29. Disconnect the pigtail adapter from the inflatable restraint steering wheel module as soon after the deployment as possible. This will prevent the
hot inflatable restraint steering wheel module canister from damaging the pigtail adapter, or the SIR Deployment Harness. The pigtail adapter and
