bennelson · 10-21-2008, 04:16 PM

My check engine light has been coming on in my '95 4-cylinder Chevy S10.

I believe this truck is PRE-OBD2, as I was never able to get the Scangauge to work with it. (Supposedly, it works on the 6-cylinder '95s!)

How do I get the "check engine light" code from the truck?

I have heard there is a way to jumper two of the pins in the diagnostic connection so that the check engine light flashes a certain number of times, and you get the error code that way.

How do I do this? Which pins do I jump? What else do I need to know?

Thanks in advance!
