I have been trying to figure out an ongoing intermittent BCM issue with my truck. - first the parking sensors stopped working, got replacements and still non functional. don't really care about these as I disable them anyhow. - second the TPMS sensors intermittently stop working and if these go out then - the third issue which is theeee most annoying issue is the remote entry fob does not work - this is my major desire to trouble shoot this. When i scan the truck with an XTool scanner noth8ing shows up, i can function most things which i have been able to sort through but no luck yet. Has anyone had wiring issues? broken wires or broken insulation leading to ground out? or could it be the BCM itself?
