2009 Jag XK 4.2l second air system reset to ready state

Just tried a smog check in Cali after hard reset.
did long drive and went to smog station.
all systems reset except;
1) second Air System (not ready)
2) Oxygen sensor (not ready)

what is the procedure to reset these two systems.

FYI I do have a FOXWELL 809 bidirectional scanner.
I believe the reset takes a drive cycle procedure though. Any info would be much appreciated!!

Take a look at this article:

May be more specific info in the service manual.

Exactly right. I typically let 2 weeks go by between the reset and the test. And I follow those very guidelines, @kj07xk .
The other thing I do is use only 91 octane (no higher) prior to the test and no "stomping on it".
