    I have a 2016 KW T680 that came with on guard system what is giving me a lot of trouble, this junk is off guaranty and every time that I take it to the KW dealer is a money pit, problem is that get the engine light on every so often and they need to re-adjust the radar of the on guard system, they willing to disable on guard but they told me they have to disable ABS and TC as well what I don't willing to do.

    Is anyone know if this is true that On guard is tie to ABS and TC?

    any suggestion will be appreciate.....

    If it is the one with the box on dash. Before turning the key to on hold in both buttons then turn key to on. It is now disabled.

    You don't have to unplug it. Just try key off hold both buttons in and turn key on
