The pressure inside the system reaches 20 bars and the minimum pressure switch ( ) L J ) opens.
Following occasional pressure increases (e.g. rough road surface), the minimum pressure valve ( ) L J ) opens.
The excess pressure is relieved by means of the solenoid valve ( ) L J ).
Furthermore, the ECU cyclically closes the solenoid valves for short times during vehicle operation (raising condition, see next paragraph) to keep the hydraulic circuit pressure in the range of 20 bars.
