I have recently replaced the Speedo clustser in my 03 TJ with a used cluster that displays lower than actual mileage. Before replacing the cluster, I read posts and was reassured by the local Jeep dealership that the actual mileage could be read from the ECU and programmed into the cluster, and after the fact they are now claiming that it cannot be done. Is there any hope of having the correct mileage displayed on my odometer? I currently have about 78k on the vehicle and am displaying
I guess if the unit doesn't let the smoke out you could just report the cluster change to the department of motor vehicles with the new odometer reading so you don't ever get dinged for 'turning back' the odometer. I know that when used car places do that around here, (change clusters) they get an 'unknown' mileage designation on the registration that follows the vehicle's life.
I would almost suspect if you looked close at the board's chips you might find one with a sticker on it. In one generation of memory chips they put a window under this sticker so you could remove the sticker and erase the chip using UV light. Put the sticker back on and reprogram. Some are also electrical erase and some are one time only program.

It implies in the post that the 'new' chip will pick up the programming 'sort of' but then goes on to say the replacements come with the VIN in there....
That could mean you need a clean PROM and a computer or a clean PROM and a vehicle.... I really don't know the answer.
Maybe one of the 'factory' techs that hang around here knows?
