  3. Place driver-side air bag module on ground in center of an area 6 feet (1.8 m) in diameter with trim cover facing up. Connect pigtail adapter to driver-side air bag module connector. Extend SIR deployment harness and pigtail adapter to full length. Place a 12-volt battery near shorted end of SIR deployment harness.
  4. Separate 2 banana plugs on SIR deployment harness. Connect SIR deployment harness wires to battery. See Fig 1. Driver-side air bag module should deploy. If driver-side air bag module does not deploy, go to step  7. If driver-side air bag module did deploy, disconnect SIR deployment harness from battery. Short 2 SIR deployment harness leads together.
  5. Using SIR Deployment Fixture (J-39401-B) to hold air bag module, repeat deployment procedure for passenger-side air bag module and driver side impact air bag module.
  6. DO NOT touch metal surfaces of air bag modules for at least 10 minutes due to heat generated during deployment. Wear gloves and safety glasses when handling deployed air bag module. Wash hands with mild soap and water after handling. Dispose of deployed air bag module as you would any other part. Inspect pigtail adapter and SIR deployment harness for damage after each use.
