    Had a bunch of lights come on at about the same time and they've knocked my cruise control out...Have a couple of traction control lights, ABS error code, the hill start assist error code, and the forward facing radar error code...I was told to drive it for a bit and cycle through some start ups but I've driven 1500 miles now with many start ups, and still nothing....Anyone have a clue as to what it might be ? Thanks BT

    We parked and shut the master switch off,let it sit for awhile ,then re started.Most of the time it would clear all those errors,but we had Freightliners.I don't know if the 579's have a master switch.

    I took my truck in this morning and calibrated ABS and all the lights went off. Everything‘s working the way it supposed to.
