Part name Function
Inlet solenoid valve
! Adjusts the fluid pressure in each brake system according to DSC HU/CM
signals.
Outlet solenoid valve
! Adjusts the fluid pressure in each brake system according to DSC HU/CM
signals.
Stability control solenoid valve
! Switches the brake hydraulic circuits during and according to normal braking,
ABS and EBD control, TCS control and DSC control.
Traction control solenoid valve
! Switches the brake hydraulic circuits during and according to normal braking,
ABS and EBD control, TCS control and DSC control.
Reservoir
! Temporarily stores brake fluid from the caliper piston to ensure smooth
pressure reduction during ABS and EBD control, TCS control and DSC control.
Pump
! Returns the brake fluid stored in the reservoir to the master cylinder during ABS
and DSC control.
! Increases brake fluid pressure and sends brake fluid to each caliper piston
during TCS control and DSC control.
Pump motor ! Operates the pump according to DSC HU/CM signals.
