Picked up my truck this afternoon, so far so good, hopefully it is fixed. Here's what my receipt says.
"Faulty steering column module and poor connection pin 49. Pinpoint test found faulty steering column module and clock spring, replaced module, attempt to install datafound no communication with pcm. Contact tech hotline performed pinpoint test A found circuit VDB05 had 22k ohms of resistance. Inspected harness and circuit found damaged pin fit in connector 212, pin 49 repaired pin and retest performed PMI on module and program, road test and retest"

So far so good
I hadn't driven the truck much until yesterday went about 80 miles yesterday with a few stops & about the same distance this morning with a few stops & so far its running flawlessly. Hopefully it will continue.

Just FYI, the clock spring basically connects the electrical items on and in the steering wheel to the computers / power sources that are located elsewhere in the vehicle. This would include all your steering wheel buttons for cruise control, the message center controls, volume controls, airbag, horn, and steering angle sensor (for stability control).
Basically the clock spring itself is not a spring - its a round disc about the size of a hockey pock and it has a large ribbon wire inside it, which is wound up half-way at dead center steering. That way, if you turn left, it can finish winding all the way up without stretching the wires, or completely unwind without damaging the wires if you turn right. On these Super Duty trucks, there is a SCCM - or steering column control module - which relays all the power and information back and forth.
The SCCM is programmed to a truck's VIN#. Basically, if you put in a VIN for an XL level truck, the SCCM will not look for the 5-way controls on the left side of the steering wheel used to control the fancy LCD dash message center. Instead, it will look for the simple 3-way switch for the basic message center. Since there are so many variations between trim levels and available options, the VIN tells the SCCM (and other modules) exactly which options your truck has, and to enable "those" options.
The 4.2" LCD display has been used in Ford trucks since 2011 in both the F-150 and Super Duty. I'd say overall it is very reliable. Too bad that you had issues with yours, but I suspect it will be fine now.
