Today my truck had the check engine light come on. The code reader gave me U0412 and POACO. It says it's a Invalid Data Recieved from Battery Energy Control Module. Can anyone give advice of how fix it

That sounds to me like the e-torque battery might need checking. I think there are some longer warranty terms for those batteries so it might be worth checking your paperwork to see if it is covered.
