Operation CHARM: Car repair manuals for everyone.

Inside of the Vehicle

CAUTION: When you are deploying an inflator module for disposal, perform the deployment procedures in the order listed. Failure to follow the procedures in the order listed may result in personal injury.

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. Disable the SIR system. Refer to Air Bag(s) Arming and Disarming.
2. Put on safety glasses.
3. Remove all loose objects from the front seats.
4. Disconnect the inflatable restraint steering wheel module coil connector (1).




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




7. 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 steering wheel module deployment harness.
8. Strip 13 mm (0.5 in) of insulation from both ends of the wires cut in the previous step.
8. 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.




10. Twist together one connector wire lead to one deployment wire.
11. Inspect that the previous connection is secure.




12. Bend flat the twisted connection.
13. Secure and insulate the connection using electrical tape.




14. Twist together, bend, and tape the remaining connector wire lead to the remaining deployment wire.




15. Connect the deployment harness to the steering wheel module coil connector (1).
16. Route the deployment harness out of the driver side of the vehicle.




17. Disconnect the inflatable restraint IP module connector (3).




18. Cut the IP module harness connector out of the vehicle, leaving at least 16 cm (6 in) of wire at the connector.
19. Strip 13 mm (0.5 in) of insulation from each of the connector wire leads.




20. 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 IP module deployment harness.
21. Strip 13 mm (0.5 in) of insulation from both ends of the wires cut in the previous step.
22. 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 the inflator module is ready to be deployed.




23. Twist together one connector wire lead to one deployment wire.
24. Inspect that the previous connection is secure.




25. Bend flat the twisted connection.
26. Secure and insulate the connection using electrical tape.




27. Twist together, bend, and tape the remaining connector wire lead to the remaining deployment wire.




28. Connect the deployment harness to the IP module connector (3).
29. Route the deployment harness out of the passenger side of the vehicle.
30. Completely cover the windshield and the front door openings with a drop cloth.
31. Deploy each deployment loop one at a time.
32. Stretch out all of the deployment harness wires on the left and right side of the vehicle to their full length.
33. Place a power source, 12 V minimum A minimum, such as a vehicle battery, near the shorted end of the harnesses.

IMPORTANT: The inflator module will deploy when the wire ends contact the power source.

34. Separate one set of wires and touch the wire ends to the power source in order to deploy the inflator modules.
35. Disconnect the deployment harness from the power source and twist the wire ends together.
36. Continue the same process with the remaining deployment harnesses that are available.
37. Remove the drop cloth from the vehicle.
38. Disconnect all harnesses from the vehicle.
39. Discard the harnesses.
40. Scrap the vehicle in the same manner as a non-SIR equipped vehicle.
41. If one or more of the inflator modules did not deploy, perform the following steps to remove the undeployed modules from the vehicle:
^ If the steering wheel module did not deploy, refer to Inflatable Restraint Steering Wheel Module Replacement.
^ If the IP module did not deploy, refer to Inflatable Restraint Instrument Panel Module Replacement.
42. Call the Technical Assistance Group for further assistance.
