A local auto parts store may have a scanner that can give you the DTCs. If not, a dealer certainly can diagnose it for you.

It's best to get your Corvette to a dealership, so they can scan for codes which will shed some light on why this alert has come on. If you need help connecting with your local Chevrolet dealership, feel free to email us at socialmedia@gm.com. Please include your Username and Forum title in the subject line if you do contact us.

Did you replace your windshield recently? That caused my car to set off that message. Dealer had to update the computers to fix it; however, there is a TSB relating to it where you don't have to update the modules. I can't find it so if anyone else is handy maybe they can post it.
Edit: I think i found the TSB https://static.nhtsa.gov/odi/tsbs/20...12260-9999.pdf

Someone suggested in another thread was to disconnect the battery for 15-30 minutes and see if that clears it. Also, make sure your battery is fully charged. Weak batteries can throw all sorts of codes. I'd do those as easy tests before spending money at the dealer.

I will try disconnecting the battery tonight and let you know. I recently replaced the battery and had a problem with all systems not working due to the main power cable being mis-alligned. 
Maybe that set off the "service theft alarm. Thanks.

Quite possible. I'd also put it on a charger and make sure it's topped off and when you hook it back up make sure you ensure everything is seated properly and that little black wire isn't damaged.
