Hi there, new member here with a 2022 I picked up in March. I was wondering if you actually clicked the button yet and verified the Elite Fit performed the flush? Or has anyone else confirmed this for any C8s before 2023 with this scanner? Thanks!

There was another post a while back that seemed to suggest that the scan tool actually writes the code into the tcm (apparently only needed for the 2020-2022). It was part of a statement from the maker of one of the devices that will not do it, and that was the reason given, that it could not update the tcm. Don't know if it is accurate. But the question is, once completed one time using Techline Connect, is the code now in the tcm, so it could in fact be completed with a 3rd party tool?

Not to be Debbie downer but unfortunately it won't work on the 21. As of today the Launch can only trigger what the tcm has programmed. That may change in the future. It does work on 23-24.

So for 2023s+ can the 3rd party scanners now do the flush procedure without a money-grab GM subscription?

As said above only 23+ can be done with 3rd party tools period. Maybe that will change in the future but not as of now. Techline Connect can do all years the same as the dealer but you need a vin unlock and 3 day subscription.

Thank You mortelec. I thought you only needed the three day subscription to download the GDS2 software from https://www.acdelcotds.com/subscriptions. But you need both, the vin unlock at $45 for 2yrs, and a subscription at $64 for three days. Plus the cost of the MDI2 hardware and laptop which i got.
Does the GSD2 software update the MDI2 or you need to download the software from Bosch for that as well?

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.
