• The ABS performs a self-diagnosis test for a few seconds each time the vehicle first starts off after the 

main switch was turned on. During this test, a “clicking” noise can be heard from front side, and if the 
front brake lever or rear brake lever is even slightly operated, a vibration can be felt at the levers, but 
these do not indicate a malfunction.

EAS30710

ABS OPERATION

The ABS hydraulic circuit consists of two systems: the front wheel, and rear wheel. The following de-
scribes the system for the front wheel only.

Normal braking (ABS not activated)

When the ABS is not activated, the inlet solenoid valve is open and the outlet solenoid valve is closed 
because a control signal has not been transmitted from the ABS ECU. Therefore, when the brake lever 
is squeezed, the hydraulic pressure in the brake master cylinder increases and the brake fluid is sent 
to the brake caliper.
At this time, the inlet and outlet check valves of the hydraulic pump are closed. As a result of eliminating 
the orifice, the brake master cylinder directly pressurizes the brake caliper during normal braking. When 
the brake lever is released, the brake fluid in the brake caliper returns to the brake master cylinder.
