I have a USA model Nightster 2008 model. I recently re-programmed the ECM and now it is showing side stand on the speedometer and engine trouble icon lit. My bike does not have a side stand switch as it is a USA model. It will go off when i press the reset button at the back of the speedometer but the engine trouble icon remains lit all the time. How do i permanently get rid of this error message from my speedo?
