What's up guys, picked up my '15 F350 a few weeks ago for a steal from my buddy's dealership. It is a bit higher mileage (61k) but nothing that would scare me away since it's almost 2 years old now. Everything seemed to be functioning as it should until this weekend. Trailering my gf's car home from a race down in Joliet, Illinois, I went to hit the brake on the freeway to slow down for some traffic and the truck wanted to pull hard right, enough that it made me and everyone else in the truck pucker a bit especially with the trailer attached to the back. Assuming initially that it was one of the trailer brakes locking up, I tested the Trailer Brakes with the TBC and everything slowed down smooth and straight as it should. Within 2-3 miles, the Service AdvanceTrac flashed up on the info screen and the AdvanceTrac and ABS lights. Once the lights kicked on everything acted normal.
Flash forward to a few hours later, stopped, got food, got back out on the road and both lights were off. Cool. Drove a good amount of miles down the road before the lights kicked back on again. It alternated being on and off for the remainder of the trip with the majority of it being on. Once we got home and unloaded the car off the trailer, with no warning lights, as soon as you tapped the brakes, you could feel the ABS pulse kicking on. Then like earlier, the Service screen would pop up.
Thinking it could just be a short in the trailer, unloaded the trailer Sunday and didn't think about it Monday. Drove to work fine, stop and go to downtown and back no big deal. Hopped in it yesterday and as soon as the truck turned on so did the warning screen and lights. So now it seems to be every other day, the lights are on, and if it the brake pedal ABS kicks as soon as you touch the pedal, the lights will flash on within a few minutes. Occasionally the truck will pull hard right on braking and that also will set off the service AdvanceTrac.
I'll be getting underneath the truck after work today to try and track down any loose or unhooked sensor, or obviously chaffed wires, but what are other possible sources of this problem?
Thanks in advance!
