How do you know when the Engine is running in VCM mode which shuts down the number of cylinders? In my Vette, there is a display that shows if The car is in V8 or V4 mode. Is there such a display or indicator in the Odyssey?
I know this is an old post but!! I just installed the S-VCM muzzler into a 2019 Odyssey. Even with the muzzler installed and VCM deenergized, the green halo light still is on unless you accelerate. Soon as you cruise speed again the green light comes back on.Hey what do you know, learned something new. Only thing i can think of that might indicate the VCM is the green light over the instrument display, its green during moderate throttle and changes under more aggressive throttle.
