1991 Mitsubishi ECM/ECU test, or Code reader.
Hi, I have a 1991 Mitsubishi Mighty-Max 4x4 truck with 3.0 V6, 145k miles. Is there anyway to test the ECM myself, or a trustworthy place that will test it for me (I'm afraid they'll try to sell me one whether mine works or not). Also is there a way to read the codes, I've heard that this model is too old for the standard readers. I once saw that someone was able to make their own code reader using just a single L.E.D. Light from a computer, he hooked it up to the reader socket and then counted the number of light blinks, then used that to check the code in some index.
My truck won't start anymore, I've never had any trouble with it till now, and I'm afraid it's going to be an expensive electrical fix, so I'd like to test as much as I can before investing in expensive parts that can't be returned.
Thanks for your time. - Tom
