The Hydraulic Electronic Control Unit (HECU) is composed of an ECU (Electronic Control Unit) and an HCU (Hydraulic Control Unit), so the HECU hardware includes all solenoid valves inside the unit as well as the ECU. The solenoid valves are switched to ON, OFF by HECU when the Anti-Lock Brake System (ABS) is activated. The solenoid valves function is to increase, decrease or maintain the hydraulic pressure supplied to a wheel cylinder. The HECU sets the OBDII code when the solenoid valves are not to function to factory specifications.
