2010 780 dash lights

The traction control and ABS system use the same sensors, so you may have either a sensor, ECM, or a wiring problem.

 

The unit sits under the cab, A cross member going from one side too other side of the frame where the ABS system sits. It has two sets of wires per plug plus the small airlines coming from it think six of them can't remember.

I did it to cheaply way bought a can of electric cleaner, sprayed everything down, then bought some silicone waterproof spray for electrical wires you can find this at AutoZone small yellow can. Think ARC makes it. There is a crack in the plastic or short in the wire, by spraying it with silicone help tremendously.
