The speed reduction is: truck speed: 22.14 km/h
Is not happening only on the hill but also with a small step 3/4 cm.. if you start from 1 mt it goes over it but if you slowly touch the step and then accelerate it did not go through, and the software keeps telling me that there's a speed reduction switch eneabled, don't know where thou... and ther's no Namur sensor on the mast
