First you have to take the class test to get certified. Then in order to be able to do OBDII inspections you take that on a machine. If you need an app. PM me your info and i’ll send you an app. when i’m in the office tomorrow. You can also download it from www.NYSDMV.com (vehicle safety section) its under forms but i forgot the exact form number vs- something.
