This post was just migrated to the car mechanics site:
It is a 100% electronics question and has absolutely nothing to do with cars at all. Car mechanics can't answer questions about the behavior of CAN transceivers or about line impedance.
differentialtag on the question into MV.SE's
differentialtag, which is completely different. Did I already say that I hated adjective tags? \$\endgroup\$
differentialis one of the most common "special" adjective across a huge range of different scientific fields, so it's particularly nasty! By "special" I mean "stick that word to a substantive and you have a cool sub-field" :-) Compare (just off the top of my head) differential amplifier, differential gear (mechanics), differential analysis (math), differential diagnosis (medicine), differential psychology, differential stress (geology, civil eng.) and more. UGH! \$\endgroup\$
