Activating the ODO/TRIP Economy Guage

Scott, where is the core processor. If it resides within the cluster, does that mean we can import something from Europe or Japan? (hypothetical)

The core is a small piggyback circuit board that plugs into the main circuit board for the cluster. It contains the microcontroller that runs the cluster, as well as the EEPROM where the ODO data is stored. You can swap these cores between like clusters, but not between different ones. When I say that enabling the MPG info on the AUS one would require reprogramming of the core, I mean by Toyota at the factory, it is not something that can be done in the field.

Just to share my experience with cluster boards.

I have bought a canadian(Kph) cluster from ebay for my gcc spec yaris. The whole unit is plug n play and the only missing feature is the cluster backlight due to diff harness used for gcc and canadian/us models.

Theres a small dauther board which stores the ODO/TRIP. It's not swappable( with gcc spec) for me as they have different suffix in terms of pn's and it gives me all indicator lights ON with no reading when I tried to swap their daugther boards. This conclude me that they have different programming.
