Carlo is on this like white on rice, set your truck to stock and see if the prob is still there. as far as the KAM the PCM (powertrain control module) doesn't give a rats about the clock or the presets, those are internal to the radio and it's memory power. there is still a KAM in the PCM it's self
it helps the PCM recall what altitude you were at when the truck was shut off last along with all of the trends for the engine which help it runn better and adapt to enviroment changes.
The biggest concern i have is if the KAM is dead then how would the PCM retain other trouble codes? there may be more DTC hidding in there that you need to recover.
