ABS & Traction Idiot Lights ON

Asked by Jan 12, 2017 at 08:51 PM about the 2012 Jeep Wrangler Sport

Question type: Maintenance & Repair

I'm having the same problem 2012 Jeep Wrangler Sport. My ABS and traction lights always come on & off while driving. Replaced the right rear wheel speed sensor (cost WAY too much at the dealership but that's what they recommended). Still have the same problem.  Especially if I hit a pothole or speed bump.  Ideas?  Never trust a dealership :(

It could be a bad wire. I would have it scanned for ABS codes. This would let you know which side, which wheel is having the problem. Most of the time it is in a wire from the plugin at the wheel sensor on up. Example. On my car ABS and TC light was on. I scanned to see what the problem is. It said a wheel sensor on a side I already replaced the hub assembly on. But I have a good scanner and it also said to look for broken wire. I tested the wiring up from the plugin of the wheel sensor and found a bad section. The wire was all in-tacked, not broken, I replaced that section of wire and fixed the problem. The section of wire I took out did not have continuity due to corrosion,
