If the radiator fan relay is normal, check the wiring for continuity, using the wiring diagram in this section.
Special Tool - Hand Tester: 57001-1394
If the wiring is good, check the ECU for its ground and power supply (see ECU Power Supply Inspection in the Fuel System (DFI) chapter).
If the ground and power supply are good, replace the ECU (see ECU Removal/Installation in the Fuel System (DFI) chapter).

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
