The most common occurrence is when it flashes SYS and then it goes away. It will cycle like that go back the normal and then return to SYS. The system is sensitive to a battery being in good shape and even though it is charged, you can still get a cycling SYS if the battery is week, old or not in good shape. If that’s the case, a new battery is the answer.
But the higher level more correct technical answer to SYS is that the CCM might have a code in module 1 and that it the way it is displayed. The on board diagnostics (or Tech 1 or Tech 2) will show you the code if there is one. The system for the 96 is OBD2 but that is for the PCM module 4. I believe the codes for module 1 are the same for 94-96.

The instructions on the link below must be followed to get your car to tell you which error code, in particular, it is reporting. Only then can you know what it's talking about and what, if anything, you need to do to make it happy.
