Dammit!
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

I'm an egual oportunity offender
Monday I installed rear brake pads, super easy. Then took her over to the local Chevy dealer for a new set of tires, they do the price match with Discount tire, so there is no reason not to get the tires from them, plus since I buy from Chevy I get free rotations.

Finally wired up my dash cam (it's been mounted for like a month... Lol) and washed and vacuumed it.

Mine is on the fritz. It works and then gets too hot and while it runs, does not record. Then yesterday, when it recorded a takedown of a bad guy, the camera showed that those videos were locked but when I went to read them today, they were gone!

Does anybody have any guesses as to what would make this happen?? It happened twice. I started it up and saw the abs light and didn’t see my gauges working so I thought it died after starting. So I turned the key to off, started it again and same thing. ABS light, no outside temp/compass, and gauges not working. It was running though because this time I pushed the gas and the engine rev’d but no change. Waited about 5 minutes, started it again, and it hasn’t happened since. [emoji2955] weird

I would start with cleaning your battery terminals, then check and clean the grounds under the hood. even if the LOOK fine, do them anyway.

What Wes said! How old is the battery? Even if fairly new, a bad cell can also wreak havoc on the electrical system.

10-4, will do. Thanks guys! Oh and the battery is maybe 1.5yrs old.

After the grounds and wires are checked out and it still acts up, get the battery tested. In the meantime, see if you have a friend with a bi-directional scan tool that can read BCM and Chassis codes. When the system went haywire, internal codes were stored which may shed light on what happened.
Once our youngest daughter ran down the battery in the truck. She turned the key to run and let the fan and all the lights and everything run for an hour until the battery died. The truck threw all kinds of codes and did not get itself sorted out until we got her jumped and began to clear the codes.
Someone with a Tech-2 or similar can run a test on the cluster to make sure it is ok too.

Ordered a couple of new blank keys for the tahoe. Home depot and lowes refused to cut em. Found a locksmith who cut em for 10 bucks. Programmed the first key using the youtube videos. The second spare key started the truck right up without programming. Im hella confused
