looks like you have short somewhere, if those all popped up at the same time, I would start checking the harnesses ecm, tcm, etc
Under the dash? Chasing wires sucks. I dont have a clue where to start. So all them codes did pop up at the same time, I was doing 80mph set in Cruz control for about 45 mins, then the stabilatrack light came on, truck like missed or did something in the tranny. Cuz the tranny then kinda wound up and didnt change gears up or down after coming to a complete stop. It almost seemed as if the tranny went out! So I got it to orilly and BEFORE I UNPLUGGED THE BATTERY! The OBD2 was hooked up! It showed the 14 codes. After unplugging the battery and letting it sit for a bout 20mins. Hooked it back up, no idiot lights, Hooked up OBD2 And only code was the tranny control system. It has done it once after, and I was at a red light truck running and idling smooth and all of a sudden the stabilatrack track service light came on and the truck like hicuped and started to run like crap rough and shaky. Pulled over shut her off, a little later started back up and nothing. So I'm lost.

I would start at the battery, clean the battery terminals, grounds, body grounds, check the harness on the transmission, if the TCM has an error it can make the rest of abs/traction control system go wacky, but the oil pressure codes are something completely separate so it makes me think it's bad ground or bad connection somewhere
