Hydraulic Control Unit (HCU)
WARNING: This page is about a different car, the 2016 Lincoln MKS. 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 systems. The ABS module and the HCU are attached directly together. The ABS module is available separately for service, however, the module is serviced with the HCU in the event that a new HCU is required.
