Active Tuned Mass Module Temporarily Unavailable

[Scyllint]

I have been getting this message since I bought the truck. Engine switches into eco mode, I get this message on the dash and the ATMM under the drivers seat on the frame starts vibrating like crazy. I know it is supposed to vibrate but it is excessive and sounds like it is broken.
I use the gear limit switch trick to make it stop but its annoying and I would prefer if it just worked when I wanted it to.

Anyone else have this message/issue?

It looks like about a $250 part online. I am considering just replacing it myself
Ram warranty isn't going to pay for this if I do it myself right?

I’ve been getting this warning since I purchased my truck in July I asked IG Burton seven times what it meant and they never responded so I called Brandywine truck ram up in Wilmington and it’s been there all day and they say they are trying to diagnose it?

Does anyone know how to disable the notification for "Active Tuned Mass Module Temporarily Unavailable" ?​

(I deliberately removed the two ATMMs (Active Tuned Mass Modules) on my 3500 Hemi, in order to mount AMP Research Power Steps.)


Thanks!
