I'm as puzzled as you are about the MIL being on and no codes, but I wonder
if a regular OBDII reader would retrieve codes. Many auto parts chains are
offering to read codes for free in hopes they can make a sale of repair
parts - it's a good service.
I agree with the next step if you don't get anywhere that way - reset it and
see what happens. As long as the engine runs okay and the mpg is not way
lower, the light isn't trying to tell you anything you care about. Drive
If the worst comes to pass and you have to get a replacement ECM, wrecking
yards are definitely the way to go. ECMs from '96 cars are very common in
wrecking yards now, and one with a 30 day warranty (plenty of time to make
sure you didn't get a bad one) are usually in the $100 range. You don't want
to buy one from Honda, I am sure.
