5) VSC Operation
a. General
The VSC function controls the solenoid valves in order to send the fluid pressure stored in the
accumulator to the brake wheel cylinders at the respective wheels, through routes that are different from
those used during normal braking. Thus, the function operates in the following 3 modes: pressure
reduction, pressure holding, and pressure increase. As a result, the tendency of the front wheels or the
rear wheels to skid is restrained.
