Chevy Suburban airbags and belts for every row

What happens to your Suburban's module after a crash

The Chevrolet Suburban runs the SDM, GM's Sensing and Diagnostic Module, as the controller for its supplemental restraint system. On a vehicle this size, the SDM watches a spread of impact sensors, decides whether to deploy the front bags, side curtains, and pretensioners, and the moment it fires anything, it stamps a permanent crash record into its memory.

That record is what keeps the airbag light burning after an accident. The Suburban's SDM reads its own deployment history, sets hard codes, and locks. Because that data is stored at the module level, a generic OBD2 scanner cannot clear it. The light stays on key cycle after key cycle until the module is reset in our shop.

We take your original Suburban SDM, clear the locked crash data and hard codes, and return it reading factory-ready. It keeps its original GM calibration and your VIN, so it plugs back into your truck and works on the first key cycle. You reinstall the same module GM built for that Suburban.
