This is a 2018 Silverado 2500 6.0L truck with multiple module failures. I go through the process of how to take something that seems complicated and just break it down into simpler steps and chip away at it 1 module at a time in order of known bad to level of importance.

Also I've made an Amazon Page with some of my tools, suggestions, and things people keep asking about and I'll update it and add to it as I go lol.
