Function
Wheel sensor
Detects each wheel rotation pulse of front and rear wheels
and inputs them to the electronic control unit.
ABS warning light
Warns the ABS system failure to the rider.
Fail-safe relay
Supplies the power to the solenoid valve and motor of hy-
draulic unit.
Hydraulic unit (HU)
Controls the brake fluid pressure of front and rear wheels ac-
cording to the output signal sent from the electronic control
unit.
Electronic control unit (ECU)
Outputs the operation signal to the hydraulic unit so that the
unit controls matching the road conditions according to the
wheel rotation pulses transmitted from front and rear wheel
sensors.
In case of ABS system failure, the unit activates the ABS
warning light and shuts off the power to hydraulic unit and
deactivates the ABS operation.
