NOTE
Use a fully charged battery when conducting self-diagnosis. Otherwise, the light (LED) and symbol do not light or blink.

When a problem occurs with DFI system and ignition system, the warning indicator light (LED) [A] goes on and FI warning symbol [B] are displayed on the LCD (Liquid Crystal Display) to alert the rider.
For models equipped with S-KTRC system, the warning indicator light (LED) [C] goes on and S-KTRC symbols [D] are alternately displayed on the LCD, when a problem occurs in the system.


The service code of the KIBS and ABS adds “b” at the left side of the code.
The service code of the ESD adds “E” at the left side of the code.

When the service code is displayed on the LCD, push the upper button and lower buttons for more than two seconds.
The display will return to the odometer.
When the ignition switch is turned to OFF.

The FI ECU analyzes the motorcycle conditions based
on the signals from the front/rear wheel rotation sensors
and FI sensors (such as the crankshaft sensor and main
throttle sensor), and controls engine power by reducing the
number of ignition and retarding the ignition timing. The
