Yes - you take the cable off the negative terminal of the battery and let the car sit with the battery disconnected for about a half hour until the capacitors in the ECU fully discharge. When this is done you can hook the negative cable back up and your ECU will be rest.
Also remove the fuse for the ecm (ECU) in this process and make sure you have your radio code before disconnecting the battery.
by doing that yu are pretty much doing a master reset

Does a 94 Chevy Corsica have a reset switch?
If you mean electrical reset switch, the easiest way to do this; disconnect the negative battery cable for approx. 15 minutes and this will reset your electrical system. If you have a warning light which keeps coming back on, chances are you have a problem with either a sensor or a part. In that situation, you should take your car to a professional mechanic for diagnostic testing if you don't know how to do it.
