Resetting mileage data.

mg7

looking at a 2006 yukon xl with 23k miles but engine run timer displays 173 hours. Is this a resettable timer? Is this possible?

I don't know what that is all about. Mine (2005 Yukon XL) seems to reset occasionally, currently reads 10.1 hours. Seems like it had run up into the hundred at some point. I don't know if its hours since the last time it sat idle for more than a couple days? Or if there's something wrong. Weird.

I've noticed the same thing with my 2006 Yukon XL. The engine hours are really low (less than 50), but I have 20k miles on it.
