Free case ih mxm 190 175 165 155 home made diagnostic tool 380000488 diy video calibrating service

This is a DIY electrical hack, not a walkaround: an owner shows how to build a free substitute for the OEM diagnostic tool needed to calibrate the suspended front axle on MXM 155/165/175/190 tractors after suspension work. It covers the wiring schematic, the C125 connector, pin 7/8 service switch wiring, and running the actual calibration cycle. Best for owners doing their own suspension or engine overhaul work who want to skip buying the dealer tool.
