Very useful info. Just replace a faulty switch that was not passing correct info to the PASM/ABS but the Brake lights still worked. Was scary driving round corners off the brakes and the ABS kicking in, not nice at all.
I made a quick vid to show the expected vs unexpected behaviour when testing resistance with a multimeter. I know its my first post but I'm no youTuber and just thought would be useful for some who prefer moving pictures
