I am rebuilding a 2010 Toyota Prius with damaged front. I cannot find odometer PCB to correct the mileage. I have a Digimaster 3, but I cannot locate the odometer chip with its motherboard. Does anyone know where to locate that device? Also, what is the proper chip for that car, is it 93C66 or 93C86? The original chip must have been destroyed therefore I have no reference.
