blkgenius and mortelec are correct! on 2022 and earlier C8s nothing will work other than MDI2 and GSD2 software. I tried Launch X431 v49.82 and it could not communicate with the TCM module, message was that the module rejected the command input. The messaging is nicer but it is a communication error. I tried both the flush and leak test. wadejesu, I suspect Foxwell NT 510 Elite will not work either.
I will be looking into purchasing the MDI2 hardware tool and at 64 bucks for 3 days it is still more cost effective than a visit to the dealer. In essence GM is allowing DIYers to work on their cars.
Still looking for clarification if the VIN option needs to be purchased or not if you are using MDI2 and GSD2 subscription.

Search around this site, there is a video from GM saying that for DIY, this is not necessary. GM does it because they can.

I ask because I have a VXNano I used to connect to an older (2007) gm vehicles, but I'm assuming that we require different protocols with the Global B system in these vehicles. If so I guess I get a clone MDI 2 (the red ones, not the blue ones) and go from there.
Thanks!

Do you know which protocol is being used to connect to the vehicle?

I've tried multiple of the lesser expensive hand helds and none of them even show the TCM (Transmission Control Module) as present.
I'd try my VX Nano, but I have pay for the 3 day subscription just to try it out so I'm not doing that just yet. I might pick up one of the MDI2 clones from Amazon (since it's returnable there) this winter when I get under the car to change oil, DCT fluid / filter, and some other items to prep for next race season. Might not be until end of January when I have the time to do all of that work and give this a whirl.

Yes Wadejsu, for 23 and up the third party scanners should work. The module architecture is different than in the 22 and earlier model years. I'm looking around for a second hand Bosch mdi2 and if i can't find one I'll bite the bullet. In the long run the subscription and the tool will run less than a dealer visit.
