    they use proximity sensor it is placed on chassis and measure distance to drive axle

    really i-shift used load data from J1939, not air pressure ore proximity data. Brake System computer converts air bag pressure ore leaf spring level to load data and throws it to J1939

    but before ishift did not use leaf spring distance , i saw that recently maybe 2-3years ago

    i think it is not easy to convert this , it would not be accurate hard to set right things, you need to find coefficient of spring and add fix distance
