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 all useful life.
• Irreparable damage occurred to the vehicle in a non-deployment type accident.
• Irreparable damage occurred 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. Lower the driver and passenger windows.
2. Turn the ignition switch to the OFF position and remove the ignition key.
3. Check that all inflator modules which will be deployed are mounted securely.
   • Driver inflator module is secured to steering wheel.
   • Passenger inflator module is secured to instrument panel.
   • Left roof rail inflator module is secured to left roof rail.
   • Right roof rail inflator module is secured to right roof rail.
4. Put on safety glasses.
5. Remove all loose objects from the front seats.
CAUTION: A deployed dual stage inflator module will look the same whether one or both stages were used, always assume a deployed dual stage inflator module has an active stage 2. Improper handling or servicing can activate the inflator module and cause personal injury.

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