Hiya Andy
What you can try is holding down the LAP button for 15 seconds with the key in the on position. The display will do its normal thing and then when you released the LAP button you will get EFI appear and then an error code (cannot remember if it gives you a code or the number of faults detected) try a couple of times as on mine it nevers seems to do it first time?
Below is a list of error codes from a 1 Gen bike which might help
