Volvo Repair: OBD II Code, obd ii code, generic code

Question
I had an error code on my 1998 V70.  
P0410 Secondary Air Injection System

What do I need to do?

Answer
this code does not mean anything to me volvo uses different codes this is a generic code.most common problems would be the pump is siezed from water getting in it.so you could try activating the pump with the scan tool if possible or try to supply it with a power and ground to see if it runs.other problem would be a bad diverter valve the large silver valve between the back of the cylinder head and firewall.they clog up and stick shut.also check the vacuum hoses to this valve for being broken.
