Having problems with diagnostics information in the app after OTA update. Probably just call onstar for a reboot tomorrow.

Anyone have an actual copy of this TSB #21-NA-044 mentioned here? I can't seem to find it anywhere on line.

may not be an open-source download... article states, dealer update install.


“You must bring your vehicle to a dealer for this software update. It cannot be done “Over The Air” (OTA). This software update will also be covered under warranty and you should ask for a courtesy vehicle if possible.”

I realize I need to bring it into the dealer for this update. I just wanted a paper copy of the text of what is stated in the TSB in case the dealer has no clue what I'm talking about. I keep having the "Check Reverse Lamp" warning pop up and this new software update is supposed to fix it. I'm going to bring mine in next month for the 2 open recalls I have and want this done as well.

^ i had the fix for the check reverse lamp done 2 weeks ago. It hasn't come back since. There's a thread in audio/electronics where I posted the TSB for it.

I've got the "Preliminary Information" Bulletin #PIT5777, but I can't find the TSB #21-NA-044 for the software update where you said this fixed it. Did you post it somewhere else in another Audio/Electronics thread?
Thanks.
