2001 Dodge Caravan OBD not functioning
I apologize if this has been covered elsewhere, but I could not find it.
My 2001 Dodge Caravan, 3.3, has failed its state inspection, in part, because the dealer can't connect to its OBD II. The dealer told me it might just be a fuse. However, when I checked the van for it, I can't find a fuse tagged to the OBD. Nor could I find any blown fuses. I'm checking the fuse box in the engine compartment. As far as I can tell, there are no fuses under the dash, despite my manual indicating there are. I have looked, trust me on this.
My owner's manual claims I have fuses for internal devices -- including my power ports -- that can be "reset" by a mechanic. I've gotten some indication that these are controlled by software and can be reset by using a diagnostic tool.
Anybody have any ideas? Basically, I'd like to know if there is a fuse somewhere for this unit that I can test. If not, then I'll put it in the dealer's hands.

No responses on this forum, but thought I'd post the outcome to help out anyone else who comes along with a similar problem:
The dealer determined that the problem was a burnt-out check-engine light. Now, of course, the check-engine light is on and the trouble code indicates my EGR valve needs replacement. Dealer wants $330, which includes $180 in parts that, as far as I can tell, I can get from Mopar for about $120. So, I will likely take on that task as well. I'm told one of the bolts can be tough to remove, but that it is otherwise a straightforward job. BTW, now my wife and I understand the odd beeping noise the van has occasionally made for the past several months: we now assume it was the check-engine light being activated but not illuminated ... because the bulb was burnt out. Dope slap.
