After replacing basically everything in my rear
Bearings harness and abs sensors lights are still on
Do you think the original GM bearings have something built in that sends the signal to the sensors (I used aftermarket bearings ) as original ones are $200 each ! I really need to fix this for once and for all

Is the ( encoder Ring ) built into the bearing ?

Does anyone have the answer ?
Not even the Chevy dealer knows this question

I recently pulled a couple of speed sensors from some spare rear knuckles and from the looks of the sensor and the location of the sensor, the magnets/encoder ring must be in the bearing. Per the FSM, the 2011 should have a 12 volts going to the speed sensor and the sensor sends an alternating current square wave signal the brake module. Have you checked to see if you any voltage to one of the pins?

Thanks
I guess the aftermarket ones do not have reluctor magnets inside as I have 0 voltage on both I guess I have to buy the original ones after all what a mess

If you unplug the connector at the sensor, do you have any voltage at either pin on the wiring harness? If you have no voltage on one pin, you have problems somewhere else. If the bearings were a name brand bearing, I am pretty sure they would be correct. Check one of the connectors on one of the front wheels and see what voltage is there.

FYI
Learn from someone that found out the hard way
Only use Original GM rear bearings
