Diagnostics

User Mode

In User Mode, which is the normal running mode, if an FI error occurs you will see the "FI" letters displayed in the odometer readout area.
If the FI is alternating every 2 seconds with an odometer readout & the red FI lamp on the dash is on solid, the bike will start and run in fail-safe mode.
If the odometer readout is FI & the red FI light lamp is blinking, the bike will not start.

Dealer Mode

In Dealer Mode, if an FI error occurs it will be persisted in the ECU's memory, as long as power is not removed from the ECU (i.e. battery disconnected or ECU unplugged) and the error has not been cleared.
It should be noted, that if an FI error is intermittent, the error code should be checked before the bike is turned off.
Carry a spare key and a jumper so the seat can be removed and Dealer Mode entered while bike is still running. As soon as a error is cleared it is removed from ECU memory.
