Yea that is why I said we shouldn't take the easy wrong on adjusting off tech stream (and you don't need techstresm, you can bridge terminals and get the thing to activate) The variable gear sensors have to find its center, one of my last post I said how it will throw a code if it knows the wheel is way off, but it need to be way off, and once it's back within a still pretty wide shot group it will know it's good.
I could go on and on, but to do it right, you have to have the tires pointed forward, that's what the Toyota manual techs use in the back says. You can't center wheels by feel or if they look centered, they need to be centered, you can do that by either digital or analog alignment, at that point your alignment is good and your steering wheel is strait. Your done. If you wheel is off that why you have to go into the variable gear actuator and make sure it's not off, if you purposely change the variable gear, you're off from the get go. It's a backwards way of doing it.
While definitely not the same, the closest I can think of the actuator in there is like a manual trans, it's all mechanical and connected, but I can allow slip (it's basically just lets the steering wheel slow its rotation under panic braking) the steering ratio is setup up to help turn those big tires with a heavy truck easier when in a parking lot, but that ratio could be really bad at speed with a little jolt to avoid something.
