Thanks Py for posting this information. If you don’t have the diagnostic boxes and are having trouble with a commercial code reader your OBD-II port might not be exactly what your code reader is looking for. In this case, you can make your own code reader that you can use like the original diagnostic boxes. Page 2 of this thread explains how!
