Haynes shows no Secondary Air Injection System on my vehicle for P0410 Code on 1999 GMC Jimmy

I have a P0410 code , but , Haynes manual shows I have no secondary air injection system . I can't use your normal answer because I don't have a secondary according to my Haynes manual .
Now what do i do ?

the haynes manual is not always right. look under the front either on the drivers side or passenger side for the air pump. If there is a code, then there is seconday air injection.
