9 times out of ten it's a weak battery.
Other times it can be caused by installation of an aftermarket stereo, but I'm guessing battery since most folks don't drive their cars year round, this is the most likely thing.
Check the battery, charge it up if needed and all should be well.

"If SYS flashes on the display near your fuel gauge, there may be a problem with your Corvette's electrical system. If the SECURITY light flashes at the same time, there is a problem with your theft deterrent system. Have your vehicle checked by your dealer is SYS keeps appearing."
Hope this helps.

This is if you have installed or have an aftermarket stereo:
the FIX
--------------------------------------------------------------------------------
Here it is:
If "SYS" is displayed in the LCD section of the instrument panel cluster after the customer installs a new (aftermarket) stereo, he will need to do the following:
1. Buy (2) 1 kilo-ohm 1/2 watt resistors. [Radio Shack part # 271-023. They sell them as a 2pk for .29 cents.]
2. Disconnect the negative battery cable.
3. Remove the receiver.
4. Connect one end of both resistors to ignition power. (Yellow wire in the car)
5. Connect the other end of one resistor to the purple/white wire in the car.
6. Connect the other end of the second resistor to the grey/black wire in the car.
7. Cover all connections and completely cover the resistors.
8. Reconnect the negative battery cable.
It works.....

I used the paper clip method to extract the codes. H means history code and C means current code. Here is some info that may help.

Mine did that because of the aftermarket radio that was installed before I bought it. It worked fine except for the annoying "sys" warning.
I put an original radio in it just because I wanted the "whole look". The system light then stoped "warning" me.
If you like the aftermarket, it shouldn't be a problem.
