Trip Mileage Much Higher Than Odometer Mileage

if that were the case then why are people with tech2's stating they can only change the mileage on new clusters?, seems like everyone would say "hey you just need to connect to tis2"

according to gm bulletins it's done with a (sps) external power supply and a J2534 programmer and the correct (ipc) adapter I mentioned earlier, apparently these are dealer technical tools that they should have in there shop to do the clusters.
although a few gm vehicles are done with a tech2 just not very many and not these trucks there not on the list for a tech2

the typical way for DIY is to reprogram it via serial port on a computer with the chip pulled from the cluster

holy shit 4,100 hours which is the idle counter they must have been living in the car for the heater or A/C

my grandpa had a truck it only had 1100 hours @ 108k miles no he did not drive it 100PH


it's pretty clear the odometer has been rolled back it's not very hard to do with a tech2 and only takes a few min to add thousands in value

it happens a lot

here is a pretty crocked dealer they said it has 81,504 miles
it was rolled back from 205,832 miles


according to the original auction site it was sold at
for $3,650

and with a tech2 they rolled it back to
to 81,504 https://web.archive.org/web/2019021...tahoe-ls-suv-17d0df80d4084855aae64a50ef122378


they both have damage in the passenger rear corner so it's more then likely the same one
both have the rare two tone interior as well..]
so more then likely they rolled it back

NO-**...lol!

Out of curiosity I just checked my 2005 Z71 Tahoe. I am the original owner and have performed all service on it myself. Mileage is 162,488 and hours are 1,749.

I say the mileage on that one has definitely been rolled back. Since the trip meter is easily reset, the actual mileage could be much greater than the trip meter shows.

That means your average speed is 92.9 mph! More than likely, the engine hour meter reset to zero and this usually happens when the battery goes dead.

I didn’t know that it reset itself. I have replaced the battery twice so that must have cleared the history, huh.

no its stored in the flash ram aka nvram in the cluster
that is why I was suggesting it was idle hours rather then driving hours (when its in park it starts the hour counter )

just like the crown vics accumulate time in park or neutral


if it has 4,100 hours on it they used it as a "mobile" power source so it would indecate it was used in a commercial environment
if it resets to zero hours you have a memory chip issue in the cluster..

Don’t be too trusting, Denver police just bust a “corner lot” car dealer for rolling back odometers, at least 30 vehicles

I would speculate the hours could vary depending on where you live and therefore how long you let it idle, I live in California and it gets hot as hell if I do not have to shut the truck off I don't I let it idle, mine came from Nevada so I can only assume it was used the same there 4000 hours and 100k miles (roughly).
