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 the ignition switch to the OFF position.
2. Remove the ignition key.
3. Put on safety glasses.
4. Remove all loose objects from the front seats.
5. Disable the SIR system. Refer to SIR Disabling and Enabling .

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.
6. Disconnect the steering wheel module yellow connector (1) from vehicle harness yellow connector (3).
IMPORTANT: If vehicle is equipped with dual stage air bags the steering wheel module and I/P module will each have 4 wires. Refer to Component 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.
