2013 dclb throwing P0416 Secondary Air Injection System Switching Valve B Circuit Open

Ok so i tried to do the anytime headlight mod where you tap into the solid green line...

However after doing the mod and testing for functionality, i found that the mod did not work....

I pulled everything and put everything back to stock, however after starting the truck i saw an error code P0416 (Secondary Air Injection System Switching Valve B Circuit Open) I have not tried to do a hard reset on the truck (disconnecting the battery for 5-10 min).

Has anyone had this same error? and what was the remediation?

Thanks

 

same problem I am having! any luck on what it was??
