Yes and No. Generally speaking a "Historic" code is a code that caused a trouble flag and the code is no longer present. For example: You ran through high water, it got the ignition wet which caused a random misfire (code) and after it was dry it stopped.
That does not mean the problem has gone away, it simply means the trouble has not happened in the last computer cycle of 'current codes'.
Current Code means that in 'this cycle' of the computer memory, these things have triggered a trouble flag ("This Cycle" can vary based on year, events, etc.)
Codes are normally ordered by the 'code reader' in order of importance: Critical ~ minor.
