Hydraulic and Electronic Control Unit (HECU)

The Hydraulic and Electronic Control Unit (HECU) is an integrated unit. The HECU consists of:

• hydraulic control unit (HCU) consisting of an aluminum block containing solenoid valves and a pump motor
• electronic control unit (ECU) consisting of a printed circuit board with microprocessors, integrated software and the magnetic coils for driving the solenoid valves in the HCU

Both the HCU and ECU are serviceable parts, but neither is repairable.
