Pulled the code from my 96...What does C12 mean?
I have the service manuals, which I have a hard time following, and I can't figure out what C12 means. Also, I can't figure out how to reset the "service engine soon" light. Any have any ideas?

C12 is a check digit, it just means you engaged the code display correctly. Check engine light has to be reset by an interface.

It means that the system is working correctly. No other codes? Pull off the negative battery cable for a minute to clear any lurking glitches. Over the years, my SES has lit for no apparent reason. If it's not showing any other codes, it's propably just a hiccup in the system

I'm pretty sure that unhooking the battery won't do anything. That only works on OBD I systems. A 96 has OBD II. I do agree that it is probably something small.

OBD II codes are 5 characters long Pxxxx where "P" is for powertrain and "xxxx" is the numberical code. A 5 character code will not display on the 3 character digital speedo.
You either need to take it to a shop, a parts store (some will scan it for free), buy an OBD II code scanner, or buy OBD II scanning software and interface cable for use with a laptop.
As for resetting the SES light, sometimes disconnecting the battery will work and sometimes it won't. Just recently I had a couple PCM codes that, after the problem was corrected, still required me to use my scanning software to reset/command the light to "off".

Disconnecting the battery will not reset the computer, I had the same question a few days ago and tried it. You need to have a computer interface to reset our systems.
I had a check engine light come on prior to my retrieving codes, mine was for an O2 sensor. I replaced the sensor and the check engine light hasn't come on since, didn't need to reset anything for it. The problem I have now is that I still get a code c13 for the O2 sensors, I'm not going to worry about it though, I don't think it alters the performance of the engine since the problem has already been corrected. I hope.
