Removal & Installation
The hydraulic fluid control valves are located within the Hydraulic Control Unit (HCU). The HCU and the Antilock Brake Module (ABM) are combined (integrated) into one unit, which is called the Integrated Control Unit (ICU). The replaceable components of the ICU are the HCU and the ABM. No attempt should be made to service any individual components of the HCU or ABM.
