Post-Collision Inspection

On all models except Corvette, General Motors post-collision inspection requires mandatory replacement of sensors in area of accident damage only. Area of accident damage is defined by manufacturer as area of vehicle which is crushed, bent or damaged in other ways.

For example, if a front-end collision occurred, sensors on radiator tie bar would require replacement since that portion of vehicle was damaged in accident, but sensors in passenger compartment would not require replacement. If DERM sets a Diagnostic Trouble Code (DTC) and diagnostic chart leads to a faulty sensor that was not in area of accident damage, that sensor should also be replaced.

On Corvette, replace all sensors after a deployment-level collision.
