The ECU is integrated into the hydraulic modulator as one compact unit. This reduces the size and wiring required for DSC operation. Additionally the motor relay and valve relay have been replaced by solid state final stages in the control module. The ECU and Hydraulic modulator are available as separate service components. The hydraulic unit to uses:

• Two pre-charge solenoid valves
• Two change over solenoid valves
