DTC diagnostic flow chart When I worked at a Chevy garage, we had access online to GMs DTC diagnostic flow charts. They had info on conditions for setting the code, how the code was set, proper voltages and ohms for wiring checks as well as related codes. The charts flowed from start to finish and were easy to read.
Googling such a thing only has you going to "ask a mechanic" website or
just telling to replace parts until you get lucky.
so I am asking the collective community, what sites do you all know of or use regularly or book that has the info I seek.
Thanks in advance
