Ford dealer Tech said to check for corrosion on the battery terminals, if
they’re good the check each battery individually to see if all cells are good.

"kam" is keep alive memory, which is memory in your powertrain computer that needs to always have battery power to be kept... if your battery has been disconnected, this is what caused this code to be logged. If not, you might want to check for a blown fuse to your control module or a short circuit in the wiring to your module... That is if the code is still active, if the code is a stored code it just means at some point in time the module lost power (battery disconnected, fuse pulled, ...) and now it has worked fine since...
