I went to get a smog check yesterday on my 99 sentra xe. The emissions passed, but the tech could not get the computer on my car to communitcate with their computer. It wouldn't send out a signal. Then he tryed a hand-held diagnostic tool, but that said it couldn't find a signal either. I've never messed with the ECU or electrical on my car other than audio stuff. I went to an electrial shop and they said it was a dealer item. I had this problem last year. I solved it by replacing a burned fuse, but now all the fuses are ok. Is there ANYTHING that you guys can think of that I need to do. I just want to pass the smog so I can sell the car in November. thanks. Sorry for the long post.
