  1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Turn ignition off, remove key and put on safety glasses. 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. See Fig 1.
  2. Remove driver-side air bag module. See AIR BAG MODULES  under REMOVAL & INSTALLATION. Place air bag module on ground (preferably outdoors on paved surface) at least 6 feet (1.8 m) away from any people or objects. Stretch SIR deployment harness and pigtail adapter from air bag module to its full length. Place a 12-volt battery near shorted end of SIR deployment harness.
  3. For driver-side air bag module, connect air bag module to deployment harness using Deployment Adapter (J-38826-75). Ensure area around air bag module is clear of people and objects. Verify that air bag module is resting with trim cover facing up.
  4. Separate 2 banana plugs on SIR deployment harness. Connect SIR deployment harness wires to battery. Driver-side air bag module should deploy. If driver-side air bag module did 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. DO NOT touch metal surfaces of air bag module 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 like any other part. Inspect pigtail adapter and SIR deployment harness for damage after each use.
  6. Using SIR Deployment Tool (J-39401-B) to hold passenger-side air bag module and side impact air bag modules, repeat deployment procedure. Connect passenger-side air bag module to deployment harness using Deployment Adapter (J-38826-80) and side impact air bag modules to deployment harness using Deployment Adapter (J-38826-25).
  7. Ensure that SIR deployment harness is disconnected from battery and that 2 banana plugs have been shorted together. Disconnect pigtail adapter from air bag module. Temporarily store air bag module with trim cover facing up. Contact manufacturer for additional instructions.
