Noob here, Hello everyone, I have recently purchased a 2001 Aprilia Mille. The right side of the dashboard does not function after the initial computer check. During the initial computer check, it shows the coolant temperature and the clock. Almost immediately the coolant temp and clock disappear and the word "diag" with the number 1 below that appear and remain for the entire time the engine is running. ( It worked only once, during the time it worked, I was able to reset the temperature to F, and do the clock settings, it has not worked since that time.) Any thoughts on what could be wrong please?
