^
Do not connect the SIR deployment harness to a power source until you are ready to deploy the air bag.
^
The inflator module will immediately deploy when you connect the power source.
19. Clear the area of all people and loose or flammable objects.
20. Make sure that you place the inflatable restraint steering wheel module with its vinyl trim cover facing up.
21. Notify all people in the immediate area before you deploy the inflatable restraint steering wheel module.
^
An inflatable restraint steering wheel module deployment is very loud.
^
The deployment may startle any uninformed people in the area.
22. Separate the two banana plugs on the SIR deployment harness.
CAUTION: When you are deploying an inflator module for disposal, perform the deployment procedures in the order listed:
^
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 power 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 (one foot) vertically. This is a normal
reaction of the inflatable restraint steering wheel module to the force of the rapid gas expansion inside the air bag.
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
22).
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 16).
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 23).
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.
