(1) Hydraulic Circuit Diagram
When compared to the vehicle equipped with ABS/EBD only, the internal hydraulic circuit has a
normally-open separation valve and a shuttle valve in primary circuit and in secondary circuit.
When the vehicle brakes are not applied during engine running or when applying the non-ABS
operating brakes, the normally-open separation valve and the inlet valve are open, whereas the
normally-closed shuttle valve and the outlet valve are closed.
When the ESP system is operating, the normally-open separation valve will be closed by the
solenoid valve operation and the hydraulic circuit will be established by the shuttle valve. Then,
the inlet and outlet valves will be closed or open depending on the braking pressure RISE, HOLD
or DUMP conditions.
