ABS and traction control lights keep coming on

[rbhazie]

My ABS and traction control lights keep coming on. Turning the jeep off and starting again the lights will turn off after driving a few miles and getting up to 40mph the jeep will buck a little and the lights will come back on and the jeep smoothes back out and drives normal. Tried to check for a code on the dash and nothing comes up. I have a 2016 Sahara unlimited.

Have you used an OBDII scanner to scan it for codes (both pending and stored)? That's where you need to start.

Could be a dirty or bad speed sensor.

Yes, I went to my local AutoZone store to use there scanner and no code would come up. They told me that I would have to go to a dealer to get that done.

That may be true as it may take a particular type of scanner. The codes will tell you a lot though, so I would say it's necessary.

You could use the JScan app though, as it will probably bring up the codes.

You'll need one of these to go with it:

is your steering wheel perfectly centered? Mine was ever so slightly off, got an alignment and solved my problem

most OBD scanners don't identify wheel speed sensor or abs problems, I have the same thing going on with my jeep, pain in the butt

make sure the light is on when you scan it

Check your cruise control. If it doesn’t work it is probably a wheel speed sensor. Happened twice to me. Both times it was the sensors. First left rear then the right

Sensors are 25.00 if scanner won't tell you which one replace both.They sometimes break and get weird.

A- This thread has been dead for almost 3 years now, so I bet it's been resolved.
B- The issue is more likely related to the shitty, stamped and folded factory battery terminals than a failed sensor.
C- You have fallen victim to the "similar thread" curse.
