You mean airbags have an explosive charge, seat belts work on a weighted pendulum or centrifugal clutch.The seatbelt has an explosive charge that goes off in a collision to lock the seatbelt tensioner and keep you from hitting the dashboard. The seatbelt(s) need to be replaced and the SRS system reset.
You are correct but so is jblackburn. The pre-tensioner in the seatbelt retractor is an explosive charge that activates a piston which pulls your body as close to the seat back as possible. This is done so fast you don't know it happens. New seatbelts will be required.You mean airbags have an explosive charge, seat belts work on a weighted pendulum or centrifugal clutch.
Yes and no. Insurance companies will not use used or reset parts or sensors because of liability concerns, but it's commonly done in the salvage rebuilt world. I've rebuilt a '12 Eco (low front minor hit) for my daughter. It needed front bags and belts for both front occupants. I was able to reset the SDM using a GM Tech II set to T-body Aveo. I've checked the airbag system recently with a Launch scan tool, and all sensors were visible and OK along with the resistance of all the explosive components. My brother also has a rebuilt Eco (High front hit)and his SDM was reset by an SDM reset service.It may also require replacement of the SDM (Sensing and Diagnostic Module) if it set a hard DTC. You may also need to replace the front impact sensor as well. The best thing to do is take it to a shop and have the DTCS read out. Stored DTCs in an SDM that have "deployment commanded" will require replacement of the component the DTC is for as well as the SDM.
