Some info and questions on Paccar collision/cruise. (w/pics)

So this topic seems somewhat common. I am now facing an issue with the collision/cruise system on my 2021 Pete 567.
It has the Paccar air ride front axle. The truck has always sat down in the front just slightly, even with the height adjustment to full on max spec from Paccar. So I installed a pair of blocks and when doing so, because of the fog line pull on the steering wheel, I installed a pair of 4* caster shims. Then, lowered the bag height a bit to get the rig level. All of this went very well, even knowing that the steering wheel would be off center because the effective length of the drag link would be shortened. There's always a way around those mechanical issues.
So here's how the electronic issues goes down. That blasted collision/cruise system detects the road apparently using several point of reference in real time. So it knows when you are going in a straight line or around a corner. The computer must have it's own clock that gives the system the statistical average time for a driver to adjust the steering wheel when cornering etc. I'm guess at that given how mine seems to work.
Knowing that I would be correcting the steering wheel off center, I still wanted to go out and drive the rig to know how the caster shims are working. Don't do that. At slow speed around the lot, no issues. However as soon as I hit the road and got above about 20mph, the computer sensed the truck going straight, but the steering wheel was turned right a considerable amount. This must've sent a message of slippery roads and/or a skid/slide and the TC (traction control) automatically turned on and can not be cancelled, as well the orange warning in the pictures I hope to attach here.
I called my local dealership to inquire about centering the steering wheel, but to no avail. The tech said he has no idea how to do that with a one piece fixed length drag link and would have to consult Paccar about removing the steering wheel to re-center. Ok, well, I get it, even though he's back logged weeks, he still wont help a customer that purchased the rig from his dealership. Oh well, that's why techs that go out on their own are doing so well.
Hoping that the electronic fault will be one of those that can self clear once the mechanical issues is resolved, I contacted my local suspension supplier, Oregon auto spring, and we found an adjustable length drag link that fits the criteria. Ordered. So now we wait for delivery, then install and we'll see from there.
If anyone here knows or has an idea if this fault is self clearing or not, please share.

 

At the steering box, the spline connection has a bolt relief for index in the spline shaft out of the box. At the other end of the telescoping steering shaft where it meets the column shaft at the firewall, there is a very large flat index on both the shaft and the yoke. I was really hoping either one of these connections would be non-indexed, but they are.
I have considered, but am reluctant at this point anyway, to use a burr and diy re-index the yoke at the box. But,......ya. I'm hoping to not diy this thing like that just yet.
The adjustable drag link really isn't all that bad price. I think $310. So if that can correct this issue and not have to deal with the electronics in the steering wheel,.....hoping.

 

Update:
Installed an adjustable drag link, centered the steering wheel, and all works as it should. In about the same distance that it took to throw the fault when the steering wheel was off, it self cleared the fault now that the steering wheel is centered.
