I have a PT100g Forestry that is throwing the undesired track movement code. However the speed sensors and speed sensor harness are disconnected. The code only pops up when you have the key on, machine running or not, and you lift the lap bar up. I was able to swap out the mcu with one from another machine and the issue stays. I'm thinking there is something going on with the wiring harness but that was also new about 3 years ago. I can put my multimeter on the frequency wires from the right hand speed sensor harness and I get a HZ reading when the lap bar is put up. Anyone run into this before? As far as I can see there is no relation of wires from the lap bar and the speed sensors.
