Default Computer Won't Reset - 2001 Town & Country

I'm pulling my hair out on this problem.

Around the beginning of June my car battery died on my 2001 Town and Country. I jumped the battery and headed to my service station where they replaced the battery. The mechanic warned me I might have a problem with my upcoming inspection at the end of June...when the battery dies, it erases the memory of the car's onboard computer. The mechanic advised me to drive at least 120 miles before I had it inspected.

After putting on 770 miles I drove in for my inspection. They drove the car into the garage, hooked a cable to a port located under the steering wheel and download the data into the DMV. But the computer hadn't reset itself properly, and I failed the test. I put another 200 miles on and failed again. They erased the computer's memory, I put another 200 miles on and still no luck. I brought the car to the dealer, paid them $105 to erase the computer and install updates from Chrysler. They said drive 60 miles and I put on 70. Failed again. The mechanic at the dealer said put another 40 highway miles on.

There is nothing wrong with the car, nothing wrong with the computer (so they say), and now the car is past inspection. NYS gave me one 10 day extension but won't give me another. I have to drive the car to put mileage on, but any cop can pull over and give me a ticket. I am going nuts.

There are a whole bunch of variables the computer records, and I have to have at least 11 out of 12. I keep failing the last two, with the computer showing insufficient data. I can't even pay to fix something because the mechanics say there isn't anything to fix. AAAAAGH!

Anyone have this happen to them? How did you resolve it?

Those forums are the best place to get help for your problem. Why didn't you get the computer replaced?

I'm amazed none of your "mechanics" missed the obvious and continued to reset the computer, which only made the matter worse. It's not mileage, it's drive cycles. You could drive hundreds of miles (all at once) and not complete the procedure, certain requirements have to be met.

Later Chrysler PCMs are VIN specific and not exactly cheap. Just a hunch.

The dealer wouldn't even quote me a price, he said that was the last thing I wanted to consider.

Great advice, thank you. My regular mechanic mentioned drive cycles but didn't give anything this detailed. I'm going to hit the road in a couple minutes.

Thanks for all the advice everyone.

Good luck. See sometimes Internet Mechanics are better than the real thing. Not that I am one of either

Me either I'm a computer tech by trade, I was a mechanic many many moons ago (pre 1995) but I keep up somewhat on current stuff (at least what on what I own, which currently is an 07 Dodge Charger), so I can do most of my own repairs.

I was never a mechanic, but my first car was a 1969 Mustang, and I loved fooling around with the engine. Cars these days though, I put the hood up and just shake my head. I'm lucky if I can figure out where to put the windshield wiper fluid.

I know that, but nothing else is working. It seems like he's running out of time. Still, he will definitely get good advice at the Chrysler minivan forums. There are dozens of knowledgeable posters there.
