    I have not used Mitchell 1 I have used a Snap-on scanner and it should list all the modules on the data-link. If the ABS module is not listed then it is not powered up not connected to the data-link or the module has failed. I don't know why you can see faults with the ABS unless Kenworth's body module stores them.

    well I have all the brake free trials on this snap on scanner like bendix, wabco, haldex and none of them work for this kenworth I called kenworth and it’s suppose to be wabco in it! But I can’t get any codes to show up on the computer the ABS light is on, and the in the diagnostics side of things on truck has like 6ABs codes. But most important when I turn the key it doesn’t do the normal checks like a abs system should. .

    The ABS light is on because the Body Module or the Instrument panel is not seeing the ABS
    ECU on the data-link. The ABS is not doing it's self test because there is a ABS fault or the
    ABS ICU is not powering up or it has failed which is the least likely of the three. I suspect
    there is a power supply problem to the ABS ICU. Your scanner will not see the ABS module if
    it is not powering up. The ABS faults may be stored in the KW body module.
    Where does Kenworth locate the ABS ICU?

    ABS ECM is located directly below center dash/cupholders. First thing I would check is ABS fuses. Last six of VIN and I can get wiring and fuse locations.
