I have a used 2012 Titan Pro-4X...it was purchased from a dealer as I think they call it certified used and it only had about 10000 miles...
I just now noticed a button mounted on the bottom of the dash under the steering wheel. it has three wires and goes to some type of module that has a screw adjustment for + and - ... the wires from this module goes to the body control module and is wired into it. It looks like a nice professional job but I have no idea what it does..any ideas??????
