You have to go through a bunch of different drive cycles. I would just google it. But basically you need all different types of driving - extended idling when cold and warmed up, freeway driving, low/med/high rpm, etc.

This assumes all the equipment is in working order, particularly the secondary O2. Also i am not sure if disabling any codes for example might affect cat readyness (dont think so, but not 100%)

You need to remember:

Its not as simple as driving a bunch of miles... you must allow the car to go through a series of heat cycles (cold starts).

that's just the first result from a google search, but I remember my drive cycle being a PITA on my last car getting all the monitors ready. I tried doing the googled steps (for Infiniti then), but just driving on both streets and freeway is what did it. it's tricky how it wants you to accel/decel, maintain steady speed, just didn't work out in my G35.. maybe it'll work for you, especially because you only have the 1 monitor left.

Cat ready means the cat one is fine.
