Many cars have a way to read the EEC codes without requiring any
     special hardware, usually by flashing instrument panel lights in a
     sequence that tells you the code. You usually have to short some pins
     on a special connector (on my 1991 Cressida it is in the engine
     compartment), then do something such as turn the ignition key to a
     particular position to initiate the dump of the code. I know that many
     Ford and GM products have this feature, on these cars the dedicated
     EEC reader is just a convenience.

     Check out a shop manual for your vehicle (it won't be in your owners
     manual) before you go to the trouble of building any hardware.

I am having the same problem on a ford 95 escort,  got the Chilton repair
manual and the codes are listed for the EEC and am thinking about building a
full scale readout using the 16F84 and a display.  the manual shows you how
to use a VOM and read(?) the needle swings as a readout of the code.
later......chuck
