E2 means that the servo is not responding. It could be stuck (especially if the bike has not been used for a while). Try giving the servo motor a gentle tap with the end of a screwdriver. If that does not work then you will probably need to replace it. Also, it could be the wiring or the console but thee are less likely causes of the fault. Hope this helps. Best wishes, Jon
