Greetings. The problem is that they install another PCM and turn on without problem, and checked the PCM several places that supposedly have that service and did not find anything that according to them is functional, only in the vehicle does not function does not start, and in relation to the PBC of the PCM you know some site that has the diagrams or diagrams of the PCB, or as it mentions only some authorized centers GMC, there must be some place where they have that information, here that service is bad and even that they do not repair your PCM le charge, east sonde ecuentro information on how to repair those types of modules I'm an engineer in systems and, it's all thanks I say goodbye
