Vehicle not moving
When the engine is running and the vehicle is not moving, both DCV's are closed, locking fluid in each side of the 
actuator pistons. The hydraulic pump draws fluid from the reservoir and passes it at very low pressure to the valve 
block. Because both DCV's are closed, after the fluid passes through the high pressure filter, it is directed through the 
pressure control valve to the reservoir. The pressure control valve is open fully to allow the full flow to pass to the 
reservoir. The DCV's will remain closed until the ECU detects a need to operate.
