Deployment Inside Vehicle-Vehicle Scrapping Procedures

Deploy 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 connector (2) located next to the steering column.

IMPORTANT: This 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.
6. Cut the steering wheel module harness connector out of the vehicle, leaving at least 16 cm (6 in) of wire at the connector.
7. Strip 13 mm (0.5 in) of insulation from each of the connector wire leads.

8. Cut two 6.1 m (20 ft) deployment wires from a 0.8 mm (18 gage) or thicker multi-strand wire. Use these wires to fabricate the deployment harness.
9. Strip 13 mm (0.5 in) of insulation from both ends of the wires cut in the previous step.
10. Twist together 1 end from each of the wires in order to short the wires. Deployment wires shall remain shorted, and not connected to a power source until you are ready to deploy the inflator module.
