I tried to get my car inspected and when they plugged it in it just said error, it wouldn't connect. I also have an obd2 reader and says error too. I checked all the fuses and they are good. What could it be, any ideas, only thing i did this past summer was get it tuned and install a turbo timer...
thanks

 

Sorry to bump a 3 month old topic, but did you ever fix it? I have the same problem and I have a CEL, so I'd love to be able to read the code(s).
