VEHICLE DYNAMICS CONTROL (VDC) SYSTEM
VDC
4. PRESSURE "INCREASE" CONTROL WITH BRAKE PEDAL DEPRESSED
No solenoid valves are energized. This means that the ports of the inlet solenoid valve and cut
solenoid valve are open, while those of the outlet solenoid valve and suction solenoid valve are
closed.
In this state, the fluid pressure generated by the master cylinder is transmitted to the wheel cylin-
der through the open ports of the cut solenoid valve and inlet solenoid valve, applying the brake
with an increased force. The pump is always operated whenever commanded by the VDCCM.
NOTE:
For simplicity of explanation, operation of the hydraulic control unit is represented by operation of
a single wheel circuit.
