I also was using FORScan.
Exact code comes up via the DTC as the following:C1939 - Brake Pressure Switch Input Circuit Failure
ABS light is not on, nor is any CEL light on...
EDIT: I will note I found a thread about this code.. Someone suggested warped rotors... I WILL note that just lately I have noticed that when I apply the brakes I can feel a shuttering motion. AS if the rotors are warped in a way. If I let go of the steering wheel I notice that it shimmies (not much) left and right, but you can definitely feel the truck doing a sort of squirm, shake motion when braking. More so from a moderate pressure.
