Wow, I thought global A officially took place in 2013!

If GDS2 is in fact an indicator of global A then I think 2010 was the first year, Camaro, equinox,cruze, and a few others.. That's for the US anyways..

Yeah that doesn't sound too right, I don't believe Global A was in effect at 2010 at all. Must just be backwards support from tech2 maybe.

I had to uninstall techline and install newest vx software to get gds2 to work again. I'm gonna clone my HDD and boot external and install techline and see if I can get it working. Will update if it works. I'm afraid to try a used module though as I worked on a 2010 Camaro a couple years ago that had been rebuilt. Someone diagnosed ECM so owner bought one and said it was programmed to the car. My friend was working on it (and it drove to his shop) and decided to swap the ECM and then car would not crank. Reinstalled original ECM and car would not crank. He called me and I programmed fob to new ECM, and BCM, and immo, and still no crank. Put original ECM in it and programmed it and same result. I spent a few hours and never got a crank. I finally gave up and never heard if they got it fixed. I always wondered why it wouldn't crank and then I read about global A used modules not able to be swapped. I don't know how the other ECM he got had the right Vin, but I suspect it didn't have the right immo code.
So if any module on the bus with wrong immo code can cause this condition it's not worth the risk to try a used module.

See link for years and models

And I tried tech2 to see if it would work and body code doesn't exist. I used h code and got some stuff but couldn't see all the modules.

Also, I put a switch on the fuse circuit to turn off the cluster when not driving until I can program a new one.

Update- I haven't tested programming yet but thought I would share my struggle. So if I install techline it corrupts my nano diagnostic software and after a few attempts I found the two cannot exist together. I wanted to boot clone of windows from external drive (flash-windows would not clone to it- or HDD) but my budget Asus laptop wasn't having it and my bios is newest version. I cloned original drive and installed new clone as primary and it boots fine. I partitioned new clone and tried to install another clone of windows on new partition so I can boot from either, but couldn't get it to work where windows would let me choose which OS to boot. I assume it didn't recognize another OS as it was a clone. So I installed original HDD in optical caddy and tried booting from it and got error. Windows32 system.efi file missing. Now this HDD booted fine when connected as primary. I rebooted on cloned HDD and while Asus start screen was on, it said hit any key to skip, or it would repair HDD. I let it do it's thing, and afterwards, it will boot from either HDD, I just have to choose in bios which I want. So even after searching and never found where anyone else had done this, it can be done. One copy windows, two separate bootable copies so you can run separate configurations of it. I'll update if techline will work on win 10 home with budget processor AMD A6 and only 4gb ram. Tried to upgrade ram but PC won't post after install. Motherboard has to come out for ram which is ridiculous.

Yeah maybe. I remember at the time some commodores were in Tech2 originally, then were taken out a few versions later and moved in to GDS2. Current tech2win bins dont include those models, if you want to use tech2 on them you need the certain ones from about 2010. So I think the models in tech2 vs gds2 were not by model specifically just a somewhat arbitrary line in the sand of new cars.
