General error 21000??????

Got my car retuned last night everything was good, no lights, no issues. Got in it this morning drove to the store then just as I was pulling up to work the check engine light came on. Hooked up my Sct tuner and it says general error 21000 and I can't seem to find any info on this anywhere. Someone help me out please

That's all that came up on my x4 when I scanned it. Got a shop to scan it and got the actual codes now. I was just confused cause I never head of that and when I tried looking it up someone with a Chevy van posted about it and was told to check and make sure nothing was loose on his intake. Oh well like I said in got the codes now so back to the tune shop I go

In my situation with the 2016 Mustang GT I was changing my tune like I always do and nothing different. The tune completed fine, tried starting it the next day and it wouldn't start, kept giving me weird messages like "Not detecting a key" and power to the car was minimal or no power at all??? I tried clearing out the code, still won't start? I tried boosting it up and it wouldn't start for the first 3 tries and then eventually started with no issues! The other code I was also getting was 11020 which I cleared with no issues but now the car starts fine and runs like normal!
