Thermostat???
My 09 base is showing dreaded “check coolant level” ! I did and all seems ok. Temp going from 220 to 185 degrees??? Ran in driveway with cap off for 2 minutes then ran to 2500 rpm for 4 minutes, replaced cap and checked level of overflow tank when cool. Level showing full.
Is there air in my system or is it my thermostat???

I get the 'check coolant level' a few times, it went off by itself.
I don't know why it goes on; the coolant level is always to the top.
As far as I know, there is no sensor on the coolant surge tank to indicate the level of coolant.

You're right, there is no coolant level sensor. ECT means Engine Coolant Temperature.
Look in the shop manual for an answer to why the "check coolant level" msg comes on.

the connector wire to my temp sensor got slightly pinched behind the alternator and head, when I had the heads swapped. Check that too...

There’s information about the probable cause of that message in the thread https://www.corvetteforum.com/forums...x%20it%2C%20or..
but I’ve extracted this bit from that thread
“The "Check Coolant Level" message is triggered by an algorithm that compares the rise in coolant temperature over a given period of time.
if you have issues, and they dont go away, its possible thermostat replacement may fix it, or..”
