Hello, sorry I do not have an answer or any help to this. But have a quick question regarding the Tech2. Is it able to program codes into the BCM? Long story short, my dad's 07 sierra has all the antennas, RPO codes and what not needed for remote start, but it didn't come with the code in the BCM, therefore, no remote start. I can purchase the code from GM, but nobody knows how to really get it into the BCM. Even the dealer is not positive. I am curious if I got a Tech2 if I could go in there and program that code into it to "unlock" the remote start feature. Thank you.
I hope you find the answer to this. I have remote start on my 13 Denali and I use it religiously. I will be turning to this thread if something ever happens to it. Great info here.

you "should" be able to add it, you would have to pay for the $45 techline connect sps programming, have a windows 10 pc/laptop and a mdi, not sure if the tech2 are still supported for programming via sps but maybe. but once you are able to program it you can reach out to techline support and request a "calibration file" to add auto-start.
that file will be specifically for your vin. that's the only way to get it. Otherwise chris at whites automotive could most likely do it as well.
Thank you so, so much. I really appreciate that! I have been researching the answers for a long time now. I COMPLETELY forgot about White's! That is probably going to be the route to go with it. It seems it is $199.99 to have one programmed. While I would love to do it myself. The cost of the code is from $100-$200. Then talking about getting a tech2, techline programming, mdi. That is definitely more than White's. I cannot thank you enough!

Thank you for posting these, Wes. I've read through most of it, will start doing some more troubleshooting next week.
A few more things to look at and try, but am now wondering if the dealership would be able to troubleshoot the ECM crank abort? That or maybe I should just go with an aftermarket module. There are a few in this thread that seem pretty workable. Or would those be subject to the same ECM problem?
no idea, there has to be something making it abort any one of those in the list's could be it
I have a viper system it bypasses all of the gm bs for the most part

An important discovery today - my remote start woes ARE related to my non-original t-case control module. We were on vacation over Thanksgiving week (not in the Tahoe) and I had a brainstorm: might as well try and swap back in the original control module to see if it changed anything. Got back last night and today I did the quick swap. Started right up with remote start. Tried it twice just to be sure. Swapped them back and not working again. So that's the problem, now to correct it....
I did the relearn procedure using my Tech 2 - that worked fine, but still no RS. Checked for any DTCs in the transfer case section of the Tech 2 - nothing. The only thing that seems amiss is the VIN code for the module obviously doesn't match the truck. So I'm guessing that is a trip to the dealer? I'm not sure I'm up for a software subscription and trying to get an old win 10 or XP computer up to the task so I can use the Tech 2 as a pass-through. Or is there a simpler method?
General agreement that correcting the VIN in the module will solve the problem? One thing that gives me pause is earlier in this thread, @Tozan confirmed that he did NOT have to reprogram the TCCM with correct VIN after he did the same swap as me (swap 2-speed t-case from 1-speed), and he still has working remote start. I don't know why mine is acting different, could be a programming change between his '11 and my '13.

I have a modern laptop with Windows 10 and programmed a module recently with an MDI through ACDelco. I think you proved that there are minor differences between your truck and Tozan's with regards to module/programming.
How the 14-bolt axle doing?
