As I say: if you're doing the drive cycle, it does the self tests and either passes or fails, going into ready mode or popping a code (not always a cel)
If neither are happening then you're either doing the drive cycle incompletely, or you have a problem with the computer.
What drive cycle steps are you taking? What does your drive cycle process look like?
