    1. The active control engine mount operates at idle. Signals that are synchronized to the engine speed are sent by the ECM to the No. 2 vacuum switching valve assembly that controls the vacuum applied to the mount. This engine vacuum is utilized to vary the pressure in the active control engine mount. As a result, the vibration is transferred to the rubber mount using the liquid in the mount as a medium.
