If you use a spare PCM, Does Ford have a memory program inside the PCM for mileage cross reference. Back in the 80's Dodge would compare Odometer reading to PCM reading, if off by a certain amount your warranty was void.

Id like to hear the answer to this one as well. Good question. Jim

Hmmmmmm?

The PCM does not record or keep track of any odometer readings.

BTW there is no such thing as a dumb question if you don't know the answer. We all had to learn at some point in time.

I will tell you what it does have though. It will advance the odometer for time running. Almost like an hour meter but at a slower rate. I have a friend that bought a 2000 Cobra Mustang brand new. It was trailered to his house and has never been out of his back yard but it has gained 16 miles since it came home. He pulls it out of the garage 25 feet and lets it run a while to get all the fluids warmed up. Then he backs it the same 25 feet back into the garage. When he asked his Dealer about it the dealership owner told him that all the new Fords did it. So he started watching his Expedition and saw it change a tenth sitting at a stop light one day. It is not a well known fact but it is happening to all of our trucks. I have yet to see my truck do it but I am not realy looking for it either.

Interesting FOMOGO! wonder if it works on a scroll type odometers?

I don't know how true it is on an episode on CSI Las Vegas they took the last reading on the car computer (it was an Ford Expedition) and it told them that it traveled 23 miles.

For what purpose?

I don't understand why this function would be programmed in, and what arbitrary numbers Ford would use (if true) to advance mileage due to hours, and not miles??

If it happened at a stop light in city driving, while the vehicle is in drive, that's preposterous, and I think Ford could be liable for decreasing the value of an automobile. Sure, maybe only a hundred bucks over a couple of years, but this is the stuff class action lawsuits are made of. Imagine what this could mean for warranty work... (Sure you vehicle has 35.9k, but according to your odometer...)

Unless every manufacturer is doing this, I think Ford should re-consider this routine.

On another note, it does kind of make sense...for vehicles that sit and idle for umpteen hours, might be missing neccesary maintenance if going by a mileage maintenace schedule. But it sounds as though this increase is so small, in no way could it compensate. Something sure doesn't smell right about this. I'd like to hear confirmation from ford before my blood pressure goes any higher /ubbthreads/images/graemlins/phoney.gif
