Hello.Make this thread for easydiag making adapters for not obd 16 cars (bmw 20 pin,mercedes 14pin etc....)





Since easydiag not in itself have relays for switching pins it has transistors every time you make a switch to the modul-on pin there is retained voltage around 10V which is actually K line.
By connecting the brakeoutbox can be measured which is the active pin except l line pin (15) and then there is a par of active pins energized.The one we looking is other one of 15.

For example, 14 pins sprinter shows that after selecting the module voltage is maintained at a certain pin until you change the selection of modules and then hardware changes the pin itself.
