Hi there, Gianno. I have the sister ski to yours. A 2009 RXT 255 IS and I am having the same problem. My VTS buttons on the side are inoperable, I drove it sometime like this. But then the ibr went bunk and stuck in reverse. I took it apart and found motor jammed in down position. Motor functions like new both directions when putting power to it directly. I cleaned everything up, put it back together and it did the same thing and jammed itself in reverse. Did you figure yours out???? I am stumped, but am thinking the brain in the darn module is pooched. I will look at the testing procedures provided here. 49 hours on the unit.
