Impreza RS Coupe AWD F4-2.5L SOHC (1999)
Hydraulic Control Assembly - Antilock Brakes: Description and Operation
Pressure "Hold" Action With ABS In Operation
Current is supplied to the inlet solenoid valve, and the generated solenoid valve attracting force closes the inlet port.
Since no current is supplied to the outlet solenoid valve, the output port remains in a closed state.
As a result, the wheel cylinder, master cylinder and reservoir are blocked, and the fluid pressure of the wheel cylinder is maintained constant.
During ABS operation, the pump motor continues to operate.
