Diagnostic mode not working?

Recommended Posts

Hey everyone, i'm trying to make a copy of my cars current ECU image (using ECUFlash), yet when I connect both green diagnostic wires I don't get anything, no CEL, no fans cycling, nothing. What gives? I have everything connected correctly to my knowledge, I just cant this to work correctly. :mad: Any help would be appreciated!http://i.imgur.com/CI8O9a3.jpg
