ABS issues

Just bought a 2017 Platinum. The guy I got it from had it lifted (8” readylift) and 37 13.50s. I’ll probably drop it from 8” eventually. But for now, I was on a curvy road this weekend and 3 times going around a curve when lightly on the brakes, the ABS kicked in for no apparent reason. The first time I thought maybe I had hit some black ice. The second and third time were later in the day when it had warmed up into the 50s and the roads were dry.

Is it possible that with the lift, the sway of the truck in a curve is pulling on the wires of a sensor? Just have a sensor going bad? I took it to a buddy this morning and he put the scanner on it but it doesn’t show any codes.

 

Had that on my 2012 TRD stock, every now and then driving a bit faster into the curve of the on ramp the ABS came on. Was never able to figure out what it was. Was only doing it on the driver side in a right curve. My guess is it has to do with the sensor itself. Although its functional, it might throw a slightly lower speed to the abs control module nd activate abs.

 

Mine was only in right hand curves as well. Obviously one of the sensors is sending a message to the computer that one of wheels is moving slower than the rest. I just can’t figure out why. If I could figure out which sensor it is, I’d replace it and see if it changed anything

 

You can only test if they are working. You'd need to spin both wheels at same speed and read out the signal to be able to verify difference. It didn't annoy me and I did nothing to them, just drove slower into the curve. Best bet is to check your wiring for damage and if wiring is fine, changing both sensors. not sure if its worth the money to do so. Technically in a right turn the right side wheels travels slower than the left side wheel, so might be the right side sensor.

 

Has anyone heard how you can turn ABS off? I have had issues with it offroading and turning on when I am on washboard roads.

 

Turn nannies off and see what happens. Hold the ATRAC button down for 2-3 secs and a light should come on the dash showing nannies are off.

 

Check the front wheel speed sensor harnesses, my son has a 6” lift and the wires were not routed correctly and rubbed axles.

 

I recall someone on here was having some issues with the ABS kicking in on their truck while high speed offroading and causing the brake pedal to firm up (aka. ice mode). They pulled the ABS fuse and it seemed to work for their use.

 

Good to know! I'll give it a shot. Thanks @Jrfor0
