Ok if that screen is coming up then the PCM s communicating. Can you post a screen shot of the actual failure?

Ask Your Own Ford Question
Customer reply replied 3 months ago
Ill take picture in the morning. ITs just an screen that pops up after asking you to turn ignition on and off, allows pcm to power down. Says Communication Failure check cables/fix problem try again.
Ford Mechanic: Kenny Z., Ford Senior Master Tech replied 3 months ago

OK I just wanted to see if the failure was with the server or the PCM. If the IDS is capable of pulling the current calibration levels from the TCM and PCM there is no reason it shouldn't be able to load the files to the PCM/TCM, unless there is a subscription issue with the server. When IDS checks for newer calibration levels it just pings the server, it does not download the files until you select update. If after selecting update it should go back to loading files from the server before it starts to load the data to the modules.

Run the network test, then run self test continuous codes from all modules and post results here please.

Customer reply replied 3 months ago
Ran both test took pictures of results. Cleared codes. Multiple codes will show especially after trying program com with ids then have comm failure. But they appear to all clear . truck runs fine no dash lights.

Hope pics help above could not get screen to print on my printer
Ford Mechanic: Kenny Z., Ford Senior Master Tech replied 3 months ago

Ok thanks. It is normal for these codes to set during programming, I don't see any reason why the PCM would communicate at all times except during programming. I suspect a server error on the provider end. I will opt out and see if any other experts have run into this before. Hopefully one will be along soon.
