battery malfunction dashboard symbol

Hey all. Trying to do a bit of diagnostics before a short road trip on Monday. Malfunction battery symbol showed up today on my console.
Friend helped me with a code reader to see what error codes showed up to see if we could tell if it is the battery or not. This is what it showed. Does this mean it’s a computer error and the battery is fine? I have two friends arguing about it. The dealership is closed so I’m out of luck. More just curious to know at this point if this info is actually useful! Thanks in advance.

The code does not say anything about the battery.
There is miscommunication between control module and transmisssion.
The code however can be thrown by a weak battery.
Did you check battery voltage?
