Is it possible to rollback odometer and engine hours meter?
I was checking for buying an used suburban 2008 with 25k miles and only 256 engine hours...
It made me suspicious...
Tks

Might be possible, but I think it's illegal.

Its illegal to do however people have done it

How do you roll back a digital odometer?

Is it an hour meter that is meant to be able reset for some specific purpose, like work, or maintenance, or is it supposed to be a total counter, like the odometer? 25K miles and 256 hours = 97.7 mph average, which is not possible.

Is there anyway using a dtc code reader to retrieve the correct mileage from ecm?
The dealer is able to know if there was a rollback?
Tks

My company truck has a hour meter on it and it reset before from having a super dead battery multiple times... It reset the hour meter. FWIW

I'd assume the hour meter keeps up with engine running time. That would include idling so it is possible to have 256 hours of running time.

This is correct and nowadays they have become a little more sophisticated. Some vehicles have a timer that will tell you engine idle time. The technology. Lol.

Can't Carfax help? I believe all state inspections are shown

Totally possible but it raises certain flags inside the BCM.....to the average Joe, nobody would know however.

Best to Carfax that thing up or make the owner provide that to you.

Anything is possible too though...just vet the info.

GLWP!

You would have to change the whole gauge cluster out. Some new cars will store in the ECM and will reset the cluster on it's on. It something your dealer could tell you. Look around the dash near the gauge cluster and see if there are any scratches that seems Someone has changed the cluster. Test drive it and watch the mph and see if it sticks anywhere. That's a good indication that the speed sensor was unplugged for a good while.

Milage is tracked by the bcm and wheel sensors. Even if the cluster reads 0 mph, your milage will increase if the bcm is receiving wheel sensor reports. Tried, tested, and proven on my own car. The clusters do not store any information, they just display what they are told.

I have a Silverado with an hour meter. I think all cars should have them. I remember reading on some Chevy truck forums that some people have had their hour meters reset itself because of a dead battery type issue.
