Hydraulic Control Unit (HCU): Description: Notes
WARNING: This page is about a different variant/trim than selected.
The Hydraulic Control Unit (HCU) is mounted to the Antilock Brake Module (ABM) as part of the Integrated Control Unit (ICU). The HCU controls the flow of brake fluid to the brakes using a series of valves and accumulators. A pump/motor is mounted on the HCU to empty the accumulators during an ABS stop and supply build pressure to the brakes during a traction control or ESC event.
