INPA - error code - logistic counter

[jonco]

Did a random check on error codes today and found a misfire code on cylinders 4 & 2 - see attached. Frequency is only 1 but logistic counter says 4 - can anybody explain to me how this counter works. Have tried Google but can't find anything.

Codes cleared and have not yet re-appeared so hopefully a blip I just didn't notice.

Im afraid I dont know, could it be that it is reading 4 cylinders and found an issue with one? i.e. 4 logical cylinders?

Hadn't thought of that way Brian - you may have something there.
When I think about it some error codes do have a logistical counter and some don't.
Code 62 is the common as it is `misfire on various cylinders' - codes 50 to 61 than identify individual cylinders depending on engine.
I have the 4 pot and the other codes were 53 (no4) and 51(no2) which appear to be listed in firing order.

I'll re-check in a few days to see if they have re-occurred.
