An Expert’s Note on VIN Programming: Don’t make the mistake of buying a used module from a junkyard. On these GM trucks, the PCM is tied directly to the vehicle’s security system and specific options. A non-programmed module simply will not work, leaving you with a no-start condition and a trip to the dealer on a tow truck. Our process of programming your specific VIN to this 2001 Sierra 2500 Diesel PCM ensures all systems communicate correctly right out of the box, saving you from expensive diagnostic fees and immobilizer resets.
