Electrickery - VSS signal understand required

Hi, I have a 98 24V Scorpio and trying to understand the VSS signal. My understanding so far is that is a square wave, 2.2hz per MPH per Sec, but I can't find the min-peak voltage. I've seen two outputs discussed, 0-5v and 0-14v, that's a fair difference Would any one please know. I'm trying to design a bit of circuit to attach to it. Many thanks

Try searching on the MAIN web pages for " Lock on Go" I seem to remember an article describing the signals you mention.

| But actually it is not really a problem for rectangular signals. For car electronics in any case you need to add a limitation input stage for protection purpose. (positive and negative) If you need the higher voltage, just add a transistor inverter stage. Regards Armin
