Does anybody know of a key as to what each pin of the ECU does rather than just body or engine, for example if I look at the speed sensor it has three connection to the ECU E20,E22 and B20 but which wire does what etc
Yes steve I can but that does not tell what wire does what, that just let me know that 3 wire go to the ECU so one must be the square wave signal but which one? another example is there is no mention anwhere on the diagrams about the CanBus but I know its there so which wire/pin is can+
B20 is the CAN + Here's the pin out It's in German but you should be able to work it out (Bing Translate) http://www.ducteile.de/assets/files/dowloads/59M.pdf This is from the 999 workshop manual
