Re: newbie ecm question
I thought that there was a tech article on this but can't find it.
What you do is to short together pins A & B on the ALDL connector. Then key-on, engine-off. The SES light will blink out the codes. Code 12 will be the first and is always present. It is then followed by any other stored codes.
