http://www.************************ has Hartmann fault code counters in their catalog (ordered through their web site, specific to each model MB). I think they are just a digital counter that does the same pulse counting as the above circuit, but sums the pulses and displays them as a number for you to look up in their handbook, for a lot more money. I believe it was 93 or so that MB went to more elaborate test equipment.
