The solenoid is an ON/OFF type switch. When the solenoid valve is not ordered by the PCM2 Slave to bypass the silencer, the vacuum system inlet (1) is not in communication with the outlets (2) towards the pneumatic actuators. The PCM2 Slave sends a 12V order.

Instead, when the PCM2 Slave orders the solenoid valve to bypass the silencer, the inlet (1) is placed in communication with the outlet (2). In this condition, the PCM2 Slave sends an earthing order to the solenoid valve.
