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.

•Check the correct bearing pre-load as follows:
• install a suitable tool for measuring the rolling torque on the pinion splined shaft;
• check that the rolling torque, ignoring the pickup one, is within the prescribed values.
• if this is not so, operate on spacer ( & ) L J ) thickness as follows:
• to increase torque odecrease the thickness of spacer C;
• to decrease torque oincrease the thickness of spacer C.
