Default Error code 12/ Battery disconneted....

Hoping for some expert help. Hello, Dave here. I have a 96 Cherokee, 4.0. Engine Light stays on, due to (i Think) a code 12. This is the only code I get, using the onboard read out on the dash. I have disconnected the battery, Changed the Battery, I have cleared the code with a scanner, but the light comes back on after a couple of days. I have not found out how to fix this. I understand that it is nothing to worry about, but that light just bothers me. Is there a fuse/relay i need to check? if those are okay, I maybe down to wiring or PCM? Correct?
Thanks for any advice
Dave
