As the title says . My check engine light is on after swaping in a d15b (car had a z6). I'm running a p28. How do i do to get the ecu code and read it? Thanks.
there is a little blue plug down by your ecu. take a piece of wire and stick it in the end of each hole as if to short out the plug. turn the ignition to the on position and count the blinks. then look it up. but really, you should search first.
