No idea other than battery cables seem to a ongoing issue with GM, I've read about a lot of people having the same problems but I checked all the stuff it said in the bulletins, the problem is the Lan communication a short causes all the attached modules to freak out, so it's either a broken wire or a bad module I jiggled everything I could and it won't do it unless I am driving, cleaned up this ground alsoPretty new truck to have those kinds of problems isn’t it? Why do you think the starter cable was fried?
