Hydraulic Control Unit (HCU)
WARNING: This page is about a different car, the 2018 Ford EcoSport. However, it is still accessible from the selected car via links, so may be relevant.
The HCU contains the solenoid valves, the hydraulic pump motor and the pressure sensor used by the ABS module for the ABS and stability control system. The ABS module and HCU are connected together but are serviced separately.
