I have an 01 Dodge Ram 2500 5.9 diesel. Recently I set the parking brake, loaded my trailer and attempted to move before releasing the parking brake. Turck never moved, just the everyday type putting in drive then releasing the the brake. When I did, the ABS & Brake lights came on and will not go off. I tried disconnecting the batteries to reset the computer, did not work. Took it to a mechanic. I was told there was a bad sensor (LF wheel) - replaced it. Then told ODBII indicated "Low ABS Pressure." I for one do not believe in "coincidence" for this type of thing. Can anyone give me suggestions?

 

Moved this to its own thread. Makes life easier. Welcome to DF!

I take it you have 4 wheel ABS? Going to need to get codes read, and see what it is whining about. Too many possibilities to just guess.
