Looking for ECU list of errors

Hi, I am new in this forum. I have Dodge Colt 1991. The Check Engine light is on. In my Mitsubishi service in Poland nobody could diagnose it, their computer doesn't communicate with mine (because it's Dodge), I counted impulses from computer with LED, but I don't know the meaning of errors. If anybody has it. Please send me.
