on the 95 GLX's, with OBD I, will any code cause the check engine light to come on? Or only emissions related codes? I think OBD II is different, and lights up with any codes stored. Right?
I suspect my secondary coolant pump is not working, I believe it should code on the OBD I, but don't have a light indicating any faults.
In otherwords if the check engine light is off, does that mean there are no codes to be pulled on an OBD I car?
