2015 Volvo d13 (fault code: Sa 16 dtc p02cf00)

I keep getting this fault code Sa 16 dtc p02cf00 periodically, very much appreciate some help finding what is and possible solving my problem.
Truck runs great just keep getting this fault code popping up. Fault code Sa 16 dtc p02cf00 first first started popping up when I was having problem with my battery disconnect switch, which was causing all sorts of headache’s with interior light, throwing ecm faults and hard and no starts but I have since fix the battery disconnect part but I’m still having trouble with fault code Sa 16 dtc p02cf00 that keep throwing my engine light on. I tried looking it up but I can’t really find anything..
