Active Engine Mount Description and Operation

The active vibration management system consists of two bi-state engine mounts that are specifically tuned to add damping during ignition events. The engine mounts are used to enable an optimal balance between vehicle noise/vibration performance and vehicle dynamics. This includes during key cycles and auto-start/stop events. There is a single solenoid on each engine mount that is energized during an ignition event and switched On for idle and driving events. The engine mounts are supplied with battery voltage through a single fuse. They are controlled by the Engine Control Module (ECM).
