I've had a couple cases of the parking brake light come on but at the same time had the service stabilitrack/service traction control message too. Then today, got the tighten gas cap message then parking brake light and dinger as well as the above messages again. the brake light guess off after a few seconds but have to turn off the truck and restart to get the others to go away.
I initially thought the cables might be getting pulled on when cornering hard as that's when it seemed to happen. After getting the "loose gas cap" message today I have no clue. Guess I'll be going to the dealer and hook up the old tech II. My luck, the body control module took a crap... Ugh.
I'll get some pics of how my cables are now this Friday once I'm back home.
