Yeah I was a little premature posting this, I have a code reader and just haven't hooked it up yet. Hoping for the easy answer I suppose.

Hi all, first post here so please excuse any FNG stupidity (I tried searching for this but not a ton of luck finding actual solutions). I have a 2009 Suburban that the cruise stopped working on a few years ago. I don't use it much so I never did anything about it. Recently I'm starting to get warning lights that Intellitrak and ABS need service, usually this happens only on colder mornings (California cold, so like 50 degrees or so). Also recently I've started having an issue with the park interlock not letting the truck shift out of park, again usually on cold starts and very rarely when the truck is warm. I have a feeling that there's a common sensor that these systems use that is causing all or most of these failures, and am hoping that someone can help me narrow down where to look without having to jiggle every electrical connection at every wheel to try to figure out which one might be the culprit. Can anyone loan me a clue? I've had this truck since 2010 and have done all the maintenance and repairs on it myself. It's in great shape for having been through 5 kids and I'm starting the process to get it more suited towards light four wheeling for the purpose of getting my wife and I to remote trailheads so we can backpack deeper in the wilderness. Step one is to take care of these things that effect safety and drivability, step two will be to fix random things that never bothered me enough to fix until now just to get the truck to 100% before I start in on the fun stuff.
