Diagnostics for Codes

[VetPet]

My 2001 C5 has two codes, P0410 (Secondary Air Injection System) and P1153 (HO2S Insufficient Switching Bank 2 Sensor 1). Does anyone have the diagnostic charts for troubleshooting these codes?

Thanks

Thanks for the help. Looks like I've got a Secondary AIR Injection fault (code P0410) & HO2S Insufficient Switching (code P1153) Bank 2, Sensor 1.

Any chance someone has an electrical schematic of the power center? I have no idea which of the relays is for the AIR pump.
