  2. Remove driver-side air bag module. See AIR BAG MODULES  under REMOVAL & INSTALLATION. Place driver-side air bag module, with trim cover facing up, in center of cleared area, preferably a paved, outdoor surface at least 6 feet (1.8 m) in diameter, away from any loose or flammable objects.
  3. Short 2 SIR Deployment Harness (J-38826) leads together by fully seating one banana plug into the other. Connect appropriate pigtail adapter to SIR deployment harness. Extend SIR deployment harness and pigtail adapter to full length. Place a 12-volt battery near shorted end of SIR deployment harness. See Fig 1.
  4. Connect driver-side air bag module to pigtail adapter on SIR deployment harness. Ensure area around air bag module is clear of people or loose objects. Verify that air bag module is resting with trim cover facing up.
  5. Separate 2 banana plugs on SIR deployment harness. Connect SIR deployment harness banana plugs to battery. Air bag module should deploy. If air bag module did not deploy, go to step  7. If air bag module did deploy, disconnect SIR deployment harness from battery. Short 2 SIR deployment harness leads together. DO NOT touch metal surfaces of air bag module for at least 10 minutes due to heat generated during deployment.
  6. Using SIR Deployment Fixture (J-39401-B) to hold passenger-side air bag module, repeat deployment procedure. Wear gloves and safety glasses when handling deployed air bag modules. Wash hands with mild soap and water after handling. Dispose of deployed air bag modules as you would any other part. Inspect pigtail adapter and SIR deployment harness for damage after each use.
