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 the steering wheel.

Passenger inflator module is secured to the instrument panel.

Left roof rail inflator module is secured to the left roof rail.

Right roof rail inflator module is secured to the right roof rail.

4. Put on safety glasses.

5. Remove all loose objects from the front seats.

CAUTION: When deploying a SIR component for disposal, perform the

deployment procedures in the order listed. Failure to observe
the procedures in the order listed may result in personal
injury.

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.

9. 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 driver deployment harness.

10. Strip 13 mm (0.5 in) of insulation from both ends of the wires.

11. Twist together one 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.

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 Component Connector End Views for determining
high and low circuits.
