Deployment Inside Vehicle - Vehicle Scrapping Procedure

Deploy the inflator modules inside of the vehicle when destroying the vehicle or when salvaging the vehicle for parts. This includes but is not limited to the following situations:

• The vehicle has completed its useful life.
• Irreparable damage occurs to the vehicle in a non-deployment type accident.
• Irreparable damage occurs to the vehicle during a theft.
• The vehicle is being salvaged for parts to be used on a vehicle with a different VIN as opposed to rebuilding as the same VIN.

1. Turn OFF the ignition.
2. Remove the ignition key.
3. Put on safety glasses.
4. Remove all loose objects from the front seats.
5. Disconnect the inflatable restraint steering wheel module coil connector, located at the LH side of the I/P.

IMPORTANT: If the vehicle is equipped with dual stage air bags, the steering wheel module and the I/P module will each have 4 wires. Refer to SIR Connector End Views  for determining the high and low circuits.
6. Cut the yellow harness connector from the vehicle, leaving at least 16 cm (6 in) of wire at the connector.
7. Strip 13 mm (0.5 in) of insulation from all 4 SIR wires connector leads.

    • If the steering wheel module did not deploy, refer to Inflatable Restraint Steering Wheel Module Replacement (Impala)  or Inflatable Restraint Steering Wheel Module Replacement (Monte Carlo) .
    • If the I/P module did not deploy, refer to Inflatable Restraint Instrument Panel Module Replacement .
    • If the side impact module - LF did not deploy, refer to Inflatable Restraint Side Impact Module Replacement - Front .
62. Call the Technical Assistance Group for further assistance.
