On-Vehicle Deployment

2004 Oldsmobile Bravada AWDSECTION On-Vehicle Deployment
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
  1. Before proceeding, see AIR BAG SAFETY PRECAUTIONS . Disable air bag system. See DISABLING & ACTIVATING AIR BAG SYSTEM . Put on safety glasses.
  2. Cut air bag module harness connectors from vehicle leaving at least 6" (152 mm) of wire at the connector for each wire lead. See Figure & Figure . Strip 0.50" (13 mm) of insulation from each wire lead to the connector. Cut 2 deployment wires at least 20 feet (6.1 m) long from 18-gauge multi-strand wire. Strip 0.50" (13 mm) of insulation from each connector wire lead. Twist wires together at one end to short.
  3. For driver-side air bag module, twist together wires for Stage 1 and Stage 2 high-side deployment loop wires. See WIRING DIAGRAMS . Connect twisted wire pair to end of one deployment wire. See Fig 1. Bend twisted connection flat and wrap tightly with electrical tape. Repeat procedure for Stage 1 and Stage 2 low-side deployment loop wires. Assemble a deployment harness for passenger-side air bag module in a similar manner.
  4. For side impact air bag module leads, connect lead from connector wire to end of each deployment wire. See Fig 2. Bend twisted connection flat and wrap tightly with electrical tape to insulate. Repeat for remaining connector wire lead.
  5. Remove all loose objects from front seat. Ensure no one is in vehicle. Connect deployment harnesses to appropriate air bag module connectors. Stretch wires away from car as far as possible. Cover windshield and front door openings with a drop cloth. Separate deployment harness wire ends for driver-side air bag module. Connect wires to a 12-volt battery. Air bag module should deploy. If air bag does not deploy, go to step  7. If air bag did deploy, disconnect wires from battery. DO NOT touch metal surfaces of air bag module for at least 10 minutes due to heat generated during deployment.
  6. Repeat deployment procedure for passenger-side and side impact air bag modules. Wear gloves and safety glasses when handling deployed air bag modules. Wash hands with mild soap and water.
  7. If air bag module(s) did not deploy, carefully remove from vehicle. See AIR BAG MODULES  under REMOVAL & INSTALLATION. Temporarily store module with trim cover facing up. Contact manufacturer for additional instructions.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • You smell fuel, burning insulation, or see smoke.
  • Brakes feel soft, pull hard to one side, or make grinding noises.
  • The engine overheats, stalls repeatedly, or misfires under load.
  • You are missing required tools, torque specs, or safe lifting equipment.
  • You are not confident in the next step or safety outcome.
