One thing to keep on mind, Ford only wrote programming to support options they defined for a product line. The Gen 2 TCs have a short list of tire options Forscan can choose from. These are likely the tires the factory would have supplied on varions versions of the van. Due to the computer acthitecture, these are the only options we can reverese engineer. Other Fords like the F150, F250 trucks have a wide range of tire options. These trucks have a different computer architecture and users can input a large range of tire sizes once they have converted the tire size to a hex number. Even this has limits based on the max tire size Ford designed the softeare to handle (probably due to factory tire options). Finally, as of today the Motocraft site used to download factory as built data has been locked down by Ford. It is not working and you now need an account to even get to the proper page. Ford appears to be preventing users from reverse engineering the as built coding. I don't know how/what you are using for AI, but nothing that is accessible to normal users can accurately solve these types of problems. AI currently relies on forums like this for information and unfortunaly, there is a lot of misinformation on any forum and the information is not properly documented for a specific application (model, year, trim level, country etc.)

It is strange that there are no DTCs. What happens if you disconnect the PAM? It may be pulling the network down. You may be able to disable the PAM in Forscan if the disconnected module causes too many problems. I have a 2016 but don't have a PAM so I'm just guessing.

Do you still need this?

I ran the wires behind the plastic panels on the passenger side. I used the AJB because I has the pins to add circuits.

I doubt the module is defective. I would suspect the sensors are bad even though the tire shop claims they are OK. You don't know how the tire shop made this determination so I would not do anything based on this diagnosis. The problem of course is the sensors are not accessible. A good scan tool like Forscan, Autel etc will show of the status of each tire. Without a scan tool, I don't know how you can read the sensore data. Make sure you are driving the van a while before the test to wake up the sensors. Another test is to see if you can populate the "blank" tire locations with data from the good sensors. If you are learning the sensor data by letting air out of the tires when instructed by the display in the cluster, then try fooling the van by letting air out of a different tire than the one requested and see if the van loads data into that tire's location. This will show if the BCM is "blind" to a location.

I don't understand this. The "van side" is the battery cable. This cable directly attaches to the body/frame of the vehicle. Using a good body groud connection for high amperage loads is always recommended. There is a sensor on the battery connection that measures current flowing in/out of the battery. Maybe they want this connection directly to the battery terminal to bypass this sensor?

I think those are for lights that communicate with the network. My 2016 TC and many others hyper flash based on the current draw from the bulbs. These require a resistor that draws a lot of current and gets hot.

You have to enable reading PIDs. Click on Table icon in the main page. Then go to the gear icon and look for PIDs in the module. It is not intuitive, but once you find the PID you click on it. Now you have a list of PIDs. Then you click the Play icon. Like I said, it takes some trial and error but eventually you will learn how to do it.

That white wire is not an OEM connector. I don't know what those wires are connected to.

Not every Ford has the option to remove the hyper flash. Sometimes you turn off bulb outage, sometimes your turn on LED type lamp option but most common is you must install load resistors. It is different for the Ford models.

I don't understand what you are asking. You can buy Forscan for Apple. Maybe you can get it from the Apple Store(I have Android so I don't know). https://apps.apple.com/us/app/forscan-lite-for-ford-mazda/id892347083

Yes. There is a Forscan app for Apple. Check the Forscan website for details. Payment has been a problem for Forscan.

That is the Forscan app on Android. It works great for reading data. It can't make any configuration changes.

I checked my TC and the SW switch PIDs are in the FCDIM. Here is a screenshot of the right switches when I am pressing the Vol Down button
