I have a question about potentially programming modules. I want to be able to program any module on either of my GM vehicles myself in the event one would need to be replaced without taking it to a dealer. I think it can be done with a laptop and a J-2534 pass-through but my question is in order for me to access GM's TDS do I need to be a technician or can anyone subscribe? If so then is there anyway around having to be one??
Thanks.
Thanks.
