Did you clear them and they all came back?

After clearing the codes do they only come back after a restart of the engine?

If you clear the codes while the engine is running, and then keep the engine running. Do any of them come back?
IF NO - Your new battery may not be good. My thinking here is if the voltage drops too far during cranking and all those modules are seeing their minimum voltage, it could cause those errors to pop up.

Also double check to make sure all your battery connections are good, clean, tight.

Did you reset the BMS (Battery Management System) with the new battery?

Additionally, do you have the small auxiliary battery under your passenger side, rear seat? It could be that this battery is also gone bad. It is supposed to maintain power to the truck, while the main battery is being used for cranking (to avoid the low voltage dip to the modules).

Just noticed you are holding a Livernois, so you have a piggyback controller for engine tunes? Or is this just a code reader.....

If you have a tuner installed, I would say step one is remove that and see if the problem persists....it could be an issue caused by the tuner and nothing to do with the truck itself...

If that corrects the issue, you have issues with Livernois not Ford.

This is the last of my idea's if none of that works, you may need to head to the dealer...
