When the EOBD light (bottom right, amber light) comes on after turning on the ignition, the computer has diagnosed a problem somewhere on the bike. To display what is wrong: turn off the ignition, press and hold the "A" button and turn the ignition back on. Then release the "A" button. The main display now shows "EFI", and the smaller display shows the error code.
