Def not in my case.

Was it a sudden stop, like your subframe hit the concrete block and your truck stopped in its tracks? There is an inertia sensor for the airbags, you can trip that sensor and have the airbags deploy without doing anything to the impact sensors. Similarly, there's a roll-over sensor to trigger the side airbags (if equipped) that don't need any impact sensors to be touched.
