What did you buy and how cheap was it? Never had a N/A display, but my reader will display "error" if the ignition isn't full on. If there are no codes stored it will display "no codes". It's an old Actron Pocket Scan Model CP9125 unit from the early 2000s and I paid $80 for it. Oddly enough, it's still available on the market today.
