Default need help with a coolant leak issue??(long)

I am getting a code for catylst heating below threashold. All areas of readiness are passed but 1 catalyst is throw a CEL for heating below threashold. First what side is bank 1 and what side is bank 2 ? Second if my After-run pump is leaking coolant underneath is it possible for the coolant to be dripping down on to the Cats causing heating issues(coolant changing the temp) and throwing this intermitent code. My Exhaust is fine and car runs excellent. SORRY FOR SPELLING ISSUES

Default FME, if the AR pump were leaking you would see coolant on the floor, rear center of engine....

Is the coolant level in the reservoir decreasing?

I know my pump is leaking but wondering if the leaking coolant could make its way down to the cat?? My code starting coming about the same time my coolant was starting to leak. Just a weird thought if coolant on the cat. might cause a temp change on cat causing it to send a heating CEL

Bank 1 is the passenger side. A coolant leak would not cause your issue.
