Hello, for some time the warning about the wear of the blocks in the tractor lights up. The sensors have all tested from 118ohm-132ohm, after giving the weight to 3406 the indicator goes out, the plugs checked, from the 3406b cable there is a transition to the right sensor and back to the place where the sensors are connected, I noticed that there is also a white cable with the number m34-2 on which the transition is only on the plugged-in bone to the computer, it goes along with the blue back of the vehicle. Someone will tell you how else I could check where the broken wire is and how these sensors are connected
