I have a 2016 jeep wrangler unlimited with 44000 miles. I recently had rear brakes and rotors replaced, and now every time I go to park (only turning left into a spot) my abs and traction control light comes on. It does not make any sound and seems to brake fine. Took it back to the shop and they said it has nothing to do with what they did..... completely separate systems ....Im so confused, they are a reputable shop but I never had this problem until they worked on my jeep. Does anyone have any insight what could be the issue. Thanks for any help.

 

They may have damaged a wheel speed sensor when they were replacing the rotors. It'd be an easy thing to do and not know it.

 

What chiapeteater wrote. Visually inspect the wiring to the wheel sensors for any damage. If possible, turn the wheels lock to lock as you do so. It could also just be coincidence that it occurred right after the work. One thing: Is your steering wheel straight/level when driving straight ahead? This is a critical, but easily made adjustment.

 

I would throw a scanner on it and see what sensor is giving the code. Always the first step for me.
