Hydraulic Circuit

•

The HU for DSC is equipped with 12 solenoid valves that can be activated for the ABS,
TCS and DSC operation. It has two more solenoid valves than a vehicle with four
channel ABS and TCS. The additional valves are the stability control solenoid valves,
which are closed when not actuated by the CM. One valve is used for each brake circuit.
They are in line with the brake master cylinder and the suction side of the pump in the
HU. This ensures that a sufficient amount of brake fluid is available during DSC
operation.
