Keydance, Code 12 with 420a engine

[TooFastTooG]

Heys guys. I was driving with my friends to get my carwashed and my Check engine light came on, the was still running great so after i got back I came on here and looked up the keydance thing and went back out to my car and did it, I got the code 12, so I came back and looked it up and its a Pcm problem, it said this: 12 = power disconnected from ECu in past X starts. Basically means the start of codes.

So im not really sure where to go from here, ive been doing fine searching untill now and im kinda stuck, someone told me that its a fuse, but the thing is i dont have my fuse box cover so if someone could point that out to me if thats the problem. The car is still running great, but it bothers me i dont know if this something serious. I have an all stock 1996 eclipse rs manual. Thanks guys in advance for all your help.

I don't see code 12 listed for a N/T but it usually means the battery was disconnected and so any previous CEL codes are lost.

basically 12 is the start of the codes. you had the battery disconnected in the past 50 or so key turns.
