Reprogramming Information
Which models and model years are reprogrammable for which functions?
GM started service programming of Engine Controllers with some vehicles in the 1993 model year and ramped up to nearly 100% by the 1995 model year. The last engine controllers were for diesel engines used in medium duty trucks. All OBDII ECUs are programmable.
Body and chassis controllers were reprogramable in some vehicles starting in the 1996 MY, and phased in the next few years. Today some vehicles have as many as 28 reprogrammable controllers.
