You can also check the country code in the TCU to make sure it’s correct if you have access to FORScan and remaining connected to WiFi for an update is impractical. The country code for the TCU can be found here:Rugedraw it's my understanding that something in the 4 x updates screwed up TCU settings on some trucks, this is why there not reporting to the cloud or getting updates. The cellular connectivity is broken. This is why Ford is pushing 23-PU1113-UNX-DC so hard right now, to get these trucks back online. Some of these guys will need to get there trucks connected to wifi in order to receive 23-PU1113-UNX-DC because Ford locked themselves out from sending ota's via. Cellular. Ford's only option is to send this wifi, to get them back online.
Once they get 23-PU1113-UNX-DC OTA'S will start to flow again.

In the US, the country code in the first four bits should be 5553 (55 in hex = “U” in ASCII; 53 = “S”). In Canada, it should be 4341. I’m not certain if manually correcting the country code will fix an offline TCU, but it’s evidence of a problem if the code is wrong.
