ABS light on and brake or e-brake warning light on. Shut off truck and mastercylinder? (between battery and firewall) is making a whirling noise. Had to unplug the front wire harness on top to get it to quit. Anybody?

 

Have the ABS scanned, could be a sensor, could be the ABS unit ( the thing that you unplugged )

 

I've had 3 of these trucks... all had the same issue. I just unplug the ABS pump like you did and keep goin. As long as you have a place to take it to get it inspected that doens't look at the lights or run the codes you'll be fine... I've driven the one I have now for 40k like that

 

Will prob just drive. Thanks for the answer. Least I know, I dont have to be worried about it. Get it checked out sometime when finances allow. lol
