Pete,
It usually means your battery is on it's way out, or has discharged from sitting to long. You can clear the SYS code with a scanner, or disconnect the negative battery terminal. ( you will lose all your pre-sets like radio stations) Charge the battery by taking the car out for a ride, or hook up a charger. You should charge the battery before clearing the SYS code. If the code returns, chances are you need a new battery. If the code does not return, buy a trickle charger to keep the battery fully charged when the car is not used.
Good luck.

When you see "SYS" in the IP display it means there's a central control module (CCM) fault.
Some believe this is the same as a "bad battery" warning but it's not. CCM faults can be caused by a variety of problems, one being low system voltage.
The first things to do is get the fault codes which are set in the CCM.
If one of them is for low system voltage, the problem could be the battery or some other part of the car's charging system or other electrical system issue relating to the CCM.
If you suspect the battery, have it tested. If it's bad, replace the battery, clear codes then road test.
Good luck.

Pete, I'm in Smithtown. I am the treasurer for the local chapter of the NCRS (Metroli.org) If you have nothing to do on 10/6/13
we are having a meet at Wehrmann Engineering in Hauppauge. http://www.metroli.org/pdf/2013_1006_Wehrmann Chapter Meet.pdf
We will be there from 7am until about 3pm. Maybe I'll see you down there.

Have you replaced the factory radio, or is there an aftermarket radio installed? That will cause a 'SYS' fault until you put resisters in line.

sys code on 1996 corvette
I have just finished reading an article by Andy Bogus ref. CCM codes from the 1992 and 1993 Corvettes. Does this article apply to the 1996 C4 or should I attempt to find a later article? Any help finding what this problem is will greatly appreciated. Again this is a 1996 with 14,500 miles.
