Default Trouble Code P2059

Has anyone else thrown this code with a check engine light?? All I can find on it is P2059 "Reductant Inj Air Pump Ctrl Circ/Open" what does this mean??

P2509 is Powerdown Data Lost Error. Did you recently unhook the batteries??

It had been a couple of weeks ago, that could explain the code. The CEL did come on for a couple of days but is off now. I guess there not associated.
