 Jim Grant's Tech TipsOBD II, Testing Failure Q: We have gone to OBD 2 testing and my car won't pass because it refuses to talk to their computer hook-up. Why and how does this happen? - Robert Dayvault A: On Board Diagnostic of the second generation (OBD II) are becoming commonplace in many states as a requirement for inspection. My home state of New Hampshire is gearing up for a phase in of OBD II testing this fall with plans to have a full-blown program up and going in the spring of 2005. Most of the time, this form of testing is so quick that if you blink the testing is done, computers just chat and trade information that fast. Unless, in your case the computer doesn’t want to talk and tell. When a computer doesn’t chat, it is a problem. With the testing equipment this will be an issue when having an inspection performed. What is the most common cause for this type of computer silence? A bad fuse. Yes, it is often that simple. There are many fuses involved with the computer on your vehicle and it just so happens, that there is one responsible for the computer chat feature. A check of your fuses, I bet a coffee, a fuse will get your computer yacking away again.
