Deployment Inside Vehicle (Vehicle Scrapping Procedure)
DEPLOYMENT INSIDE VEHICLE - VEHICLE SCRAPPING PROCEDUREDeploy 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.
CAUTION: Refer to SIR Inflatable Module Deployment Outside Vehicle Caution in Service Precautions.
1. Turn OFF the ignition.

28. Inspect that the previous connection is secure.
29. Bend flat the twisted connection.
30. Secure and insulate the connection using electrical tape.
31. Twist together, bend, and tape the remaining connector wire lead to the remaining deployment wire.
32. Connect the deployment harness to the side impact module - LF connector (1).
33. Route the deployment harness out of the driver side of the vehicle.
34. Disconnect the inflatable restraint I/P module connector (1), located at the RH side of the instrument panel.
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.
35. Cut the 4 SIR wires leading to the connector from the vehicle, leaving at least 16 cm (6 in) of wire at the connector.
36. Strip 13 mm (0.5 in) of insulation from all four SIR wires connector leads.
37. Cut two 4.6 m (15 ft) deployment wires from a 0.8 mm (18 gage) or thicker multi-strand wire. These wires will be used for the I/P module deployment harness.
38. Strip 13 mm (0.5 in) of insulation from both ends of the wires cut in the previous step.
39. 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.
