Hello and welcome to JustAnswer.

My name is Vlad.

This trouble code just indicates that the battery was disconnected at some stage, it does not indicate any problem. It can usually be erased with appropriate diagnostic scan tool but there is no need to do it as it does not affect your engine or transmission operation at all. This trouble code will never trigger check engine light so there must be another code set.

If this trouble code comes back as soon as you erase it, then maybe it is worth to check all fuses as when you connect the battery wrong way, it will usually blows fuses at least , and the worse scenario could be damaged electronic modules.
