03 Jeep TJ Odometer reset
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
24k
cluster that displays lower than actual mileage. Before replacing the

Re: 03 Jeep TJ Odometer reset
From the '03 TJ FSM:
CAUTION: Instrument clusters used in this model
automatically configure themselves for compatibility
with the features and optional equipment in the
vehicle in which they are initially installed. The
instrument cluster is programmed to do this by
embedding the Vehicle Identification Number (VIN)
and other information critical to proper cluster
operation into electronic memory. This embedded
information is learned through electronic messages
received from other electronic modules in the vehicle
over the Programmable Communications Interface
(PCI) data bus, and through certain hard wired
inputs received when the cluster is connected to
the vehicle electrically. Once configured, the instrument
cluster memory may be irreparably damaged
and certain irreversible configuration errors may
occur if the cluster is connected electrically to
another vehicle; or, if an electronic module from
another vehicle is connected that provides data to
the instrument cluster (including odometer values)
that conflicts with that which was previously
learned and stored. Therefore, the practice of
exchanging (swapping) instrument clusters and
other electronic modules in this vehicle with those
removed from another vehicle must always be
avoided. Failure to observe this caution may result
in instrument cluster damage, which is not reimbursable
under the terms of the product warranty.
Service replacement instrument clusters are provided
with the correct VIN, and the certified odometer
value embedded into cluster memory, but will
otherwise be automatically configured for compatibility
with the features and optional equipment in
the vehicle in which they are initially installed.
NOTE: Certain indicators in this instrument cluster
are automatically configured. This feature allows
those indicators to be activated for deactivated for
compatibility with certain optional equipment. If the
problem being diagnosed involves improper illumination
of the airbag indicator, the cruise indicator,
or the SKIM indicator when the vehicle does not
have this equipment, the instrument cluster must
be replaced with a new unit.

Re: 03 Jeep TJ Odometer reset
Wow, I just read Billy Ray's reply...
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.

Re: 03 Jeep TJ Odometer reset
Wow, I just read Billy Ray's reply...
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.

The Used cluster rhat I bought is fully functional and is in the
vehicle, it just displays the incorrect mileage
