Apparently there's a code popping that is a PCM code that they are trying to say is from my tune I had the ford performance tuned I flashed it back to stock before bringing it in but that code has been popping up a month ago. They fix it temporarily then it detects a draw and pops the code again.

And now the fun begins!! If you have the Ford Performance Tune I ask who installed it. Also you should have kept it installed.

Being a Ford Backed Tune(even though it's from Ford Performance) the technicality of it is the warranty is based from original purchase date of the vehicle and being 3 year 36,000 miles. Because it is still an aftermarket tune it is questionable if any extended warranty company(including Ford ESP) would cover it if past the 3/36.

This will be fun to watch

The same dealer I took it to installed it and it's well after the 3 year 36k and no extended warranty. they said it's been happening for a month the code has been popping up I took it off a little over a week ago though

PCM - Powertrain Control Module
BCM - Body Control Module
BMS - Battery Managment System
IPC - Instrument Panel Cluster
LIN - Local Interconnect Network (It is a single wire - Send / Receive) data communication bus.

So, for your instance, overnight battery voltage was dropping below 11.5 volts, the system was disabling modules to save battery power (voltage) for engine starts.
Prolonged under charging increases the IR (Internal Resistance) of the battery, using the battery maintainer helps in repairing (fixing) the high IR, The IR is important as it is a factor on how well the battery accepts and holds the charge.
Thanks again, you are a wealth of important information.

Welp just got told ford said I need to remove my after market accessories not sure if they mean my cat back exhaust or the fox shocks might be causing the electrical issues or maybe my orange lettering is doing it ? The tune is back to stock and my bed lights have been disconnected since last spring not a clue what else they mean. Might be picking up my truck with the message still on the dash now.

What code is it giving?

Strange - I am thinking, something to do with the tune and the flash to stock , did not actually fully flash back.

If it is tied to the bed lights, you say they have been disconnected, but is the tie in to the wiring harness for them, back to OE connection.

I think they are saying you have a Parasitic Draw, from a Aftermarket Assy.
Tune or Bed Lights (?)

He didnt say the code just said it was a pcm code that was on there but not causing any lights or messages theey are going to flash the pcm now it was the ford performance tune it's super simple to flash it back and forth never had any issues and the bed lights just connect right to the battery but I disconnected and taped the connections off so they aren't connected at all anymore only other things is a dash cam and wireless android auto connecter plugged in the cab

ok , the items plugged into the Power-Points (12v) will time out after 75 minutes.
The USB’s will time out when Sync Shuts down - when door is opened
Now the codes here will be from the -BCM

I am thinking now, that the PCM is staying powered and not entering Sleep Mode.
It appears to be the direction they are taking.
Or a corrupted PCM flash, with specific files related to the PCM control of the voltage regulator and charging system input/ output

Yeah they both shut off after the truck turns off ones 12 v the others usb don't think they would be draining power cause they turn on when the truck turns on too and i think they are going with the corrupted pcm flash but I didn't flash it a month ago that's when they said thay messaged popped up I flashed it last week

Pcm flash didn't fix the code either they checked the voltage of everything today as it sat over the weekend and everything was reading fine battery had correct voltage. I'm not sure what to do contemplating trading it in but not sure how this will affect my trade in value if that code is popping

Ok, they need to get a tech , who knows how to use a meter and check wiring.
This is where the code is needed to at least give a hint on direction.
The Check Charging System message can be generated by various codes.

I guess the code is a pcm code so it's something with that but all they did so far was flash it then they went home so not sure what they'll try tomorrow with it hopefully check the wiring but at thos point I'm nit sure if they are going to

Was told its the p160a code, and that the wiring was all checked and it's all good. They reset the code and it just comes back. Pcm is shot maybe?

It all makes sense now, and the reason for telling you to remove aftermarket products = The Tune

So, you actually had (2) issues - Charging System and This
And I suspect the Flash Back, possibly created it, now (IF) there are other codes (C) Communication codes with this then a PCM may not fix it.

The BCM is the main control for the BMS and sends the current battery voltage data to the PCM.
Which the PCM acts upon that input data by controlling the Voltage Regulator in the Alternator.

From the Manual
The smart regenerative charge system primary strategy is stored in the BCM . The BCM receives information relating to the battery condition from the battery monitoring sensor via a LIN . The BCM calculates and sends the set value needed for the generator charging voltage via the HS-CAN to the PCM . The PCM then adjusts the value received (if necessary) and sends it to the generator via a different LIN . The charging voltage is adjusted depending on various parameters, such as the current level of engine efficiency. The smallest possible set value for the generator voltage is 12.2 volts, while the maximum charging voltage can be anywhere between 14.5 and 14.9 volts. However, when the battery is in a refresh phase, the voltage may occasionally reach up to 15.2 volts. These refresh phases are required when the battery charge status is 80% over long periods of time, which increases the risk of sulfation in the battery cells.


So, with this info and (IF) there are any (C) Communication Codes (Associated) with it then it has lost the (Databus) - Communication between the BCM and PCM
I am sure that they will check this before Ford authorizes a PCM replacement.

It now sounds like they are on the right track, it is rare for a PCM to fail, but it does happen.


P160A - Control Module Vehicle Options Reconfiguration Error

Description:
This DTC sets when the body control module (BCM) detects a mismatch in configuration data and programmable parameters between the PCM and BCM.​
Possible Causes:
  • Module reprogramming
  • Aftermarket performance products
  • PCM
Diagnostic Aids:
Reprogram or update the calibration. If the PCM already has the latest calibration, carry out the relearn vehicle data procedure on the scan tool. Check for other DTCs or drive symptoms for further action. Check for aftermarket performance products. If it is necessary to install a new PCM, refer to Section 2, Flash Electrically Erasable Programmable Read Only Memory (EEPROM), Programming the VID Block for a replacement PCM.​
Application
Key On Engine Off
Key On Engine Running
Continuous Memory
All​
Refer to the Description, Possible Causes and Diagnostic Aids for the DTC.​


EDIT: I just remembered something

Did you Replace Tires with a different size tire?

and

Did you adjust Tire Size setting in Forscan?

If so, this is the reason for the Code.
