Active Control Engine-Mount System (ACM) (Odyssey, Passport, Pilot and Ridgeline)

What’s the Benefit?

This system helps provide a smoother, quieter ride.


The Feature:

Whenever Variable Cylinder Management (VCM) operates in 3-cylinder mode, it creates vibration as the engine rocks on its engine mounts. 

  • To counteract this, a separate ACM control unit monitors the vibrations and operates high-speed solenoids in the front and rear engine mounts that actively cancel each oscillation. 
  • As a result, these vibrations are not transferred to the chassis through the engine mounts and are not felt inside the cabin.
