It's actually not a code breaker, per se. When you do that procedure, it runs a diagnostic program of the SRS system, and once it realizes that everything is connected and working, it turns the warning light off. But yeah, there's actually quite a lot of things you can change in the BCM without connecting it to the Consult II computer diagnostic system that Nissan uses. I don't know any off hand, but there's a number of them listed in the FSM. Unfortunately, they're not all listed in one place; each individual parameter that can be changed is listed in the diagnostics of that section. For instance, the procedure for changing how the doors automatically lock/unlock would be in the section for doors/windows, while the airbag diagnostic procedure that I posted above is in the airbag section of the FSM. Dig through the FSM and you'll see a few of these procedures here and there.
