ABS light on

Well... my ABS light popped on two days ago. I was pulling a 6x12 trailer filled with random yard waste and other junk at the time. Not sure if that triggered it or not... So right away I changed the speed sensor on the rear diff... that is usually the cause plus it's only a 15 dollar part and 10 minutes to change out so I figured why not. The light is still on. So I go to my local Advanced Auto (where I bought the sensor from) and I get a free scan. According to their scanner, both front wheel speed sensors AND the rear sensor on the diff (which I just replaced) are bad. Does this sound right? I've heard a low battery can sometimes trigger the ABS light too. The truck continues to drive perfectly normal like nothing happened. Brakes, speedometer, cruise, etc. EVERYTHING still works perfect. Just got that damn light on... so what say you FTE? sorry for the long ramble...

I went and am going through the same thing. Light came on, I changed the rear sensor, light still on. Hooked up Auto Enginuity and it said both front sensors are bad. I checked the wiring harnesses and they looked fine. Everything works so I've just ignored the light until I pick up some new sensors... or a little square piece of electrical tape

Thanks for the quick response locknload223

I need to do my front brakes soon anyway so when I have it apart I'll check them out. Yeah this is the first time EVER I've had any type of check light pop up on my dash so it's bugging the crap outta me lol

While you're down there, replace the vacuum line that runs next to the ABS wires. It's should be dry rotted and nasty. Can't remember the size just bring a little piece into the parts store and they'll set you up.

I've got manual hubs so my vacuum lines are unhooked and zip-tied up

Just got my 2012 F350 DRW out of the shop for ABS light as well. ABS and traction control lights on the dash cluster were permanently illuminated. Took it in and they told me it was some sort of speed sensor in the front right wheel area. Fixed under warranty, no more lights.
