P0410 is either DTC 0810 or 0814 = Malfunction of secondary air injection at right bank (0810 or left bank (0814). That's one of the pitfalls of a generic OBDII reader - it's not specific enough to isolate the error. In this case, if SDS showed an error on only one bank, I would suspect a problem with the hose, not the pump, but both together would be the pump. And I'm not sure about that circuit code (was that from Pep Boys? scanner?), but the secondary air injection pump is definitely on relay O.
