Does anyone know where mileage is stored? I do know that it's not the speedometer. Due to the fact that my H is only 6 months old and have 20k miles, I decided to purchase a speedo from a GMC Canyon from e-bay that claimed to have only 7k. The cluster worked fine but it displays my current milage.

So basically what your are saying is you are trying to roll back your mileage?

[evldave]

Why would you want to change the mileage. That's crap. Go back to the Jeep forums, troll!

[deicustoms1]

I know where it's stored.

It's real easy to change, just goto the DMV and tell them you want it rolled back so you can sell it for more than it's worth. If they give you any crap, call the cops.

[HummerHawaii]

Isn't that supposed to be illegal in some state? Especially if you are registered with OnStar... They know.

wtf, all this to roll back 13K miles?

It is illegal in all states since it is a Federal Law as well as a state law in all states that I know of.
The mileage is held in the BCM, the cluster is just a dumb terminal that displays messages for the BCM.

Yes, OnStar does obtain documentation of your mileage, if you signed up for the montly reports, but not sure if they keep it on file. However, even if they did, they would not turn it over to a third party without a court order. Then again, a court order would probably be easy to obtain in a civil suit.

You could change the BCM

Yes you could, but you need a dealer to program it and they will not program a new BCM without first capturing the miles from the old BCM. If they cannot capture the miles, they must put a sticker on the vehicle, and put a note in your customer history file. That file is traceable.

I eat a lot of bananas, and fish; heavily seasoned with garlic (fish not bananas). Makes me smart, but keeps the women away.

That shady trick doesn't work on newer vehicles, they were smart enough to start storing odo readings in the computer instead of the speedo. Good thing!

[f5fstop]

In some vehicles, it is easy to obtain another BCM from a junkyard with lower mileage, and install in your vehicle. Newer ones require a Tech 2 to program it to the system.
The H3 BCM, is one of GM's latest models. It cannot be swapped from one H3 to another. Once it is programmed with a VIN, it cannot be programmed to another VIN, unless it is erased by the manufacturer or their repair facility.
And all the computers, including the radio, XM, Onstar modules talk to each other and check each other out on the serial bus.

[fourfourto]

Just put the truck up on jack-stands, throw it in reverse and watch those pesky miles just melt away....

This should work right...anybody....Bueller???

That only works in the movies.


Just install a flux capacitor and go back in time.
