I have shorted A to B but am having trouble deciphering how many times it flashes. Can someone please explain this to me in a simpler form. How do I know when to stop counting?

It flashes each code 3 times, starting with code 12 (one flash, pause, then two flashes) that indicate it is communicating. After code 12, trouble codes are next, each flashing 3 times. My 92 Suburban ends with code 12 flashing 3 times to let me know it is the end of codes.
