Hi I am Curtis,\

I am trying to fix my girlfriends ABS brakes on her 2010 Santa fe FWD 4 cylinder gas in Florida

She got the ABS warning and traction control.

Put it on the OBS scanner at autoparts and got nothing, A friend has a $10k snapon scanner and we see that the RR sensor is not communicating. I unplugged it, inspected, reconnected, still dead signal.

Looking to see what you'll know about it. Thanks

 

Check the brake light switch There's a recall and if the switch goes bad, it will make the ABS, traction control and cruise control not function.
