ABS Acting up But No TDC's

[97explorerltd]

At low speed stops the ABS kicks in and the pedal pulses. There are no codes set. After searching this forum it seems the rear abs sensor in the diff. is prone to failure so I unplugged the wire and the problem went away. Changed the sensor plugged the wire back in & problem still exists. Still no codes. Does anyone have any suggestions?

Maybe starting by bleeding the brakes to rule that out.

Does it also come up at slow speeds like when your trying to parallel park or pull into a parking space? Here's a tsb that describes your issue and how to diagnose it correctly for repair..

ABS kicking in at slow speeds is usually a problem with wheel speed sensor clearence, sounds like one of the sensors in the front hub is on its way out, if you can get ahold of an OBD2 scanner with data capabilities, see what sensor isn't reading under 7-9 MPH, mine did they same thing, turned out to be the wheel bearing/hub on the pass. side

Brickwall, did your problem leave any codes. Just finished bleading brakes and problem still exists. I also disconected the front left sensor like I did in the back and the problem disapeared but the abs light stays on.

No it didn't leave any DTC's cause the sensor was still reading at higher speeds just wouldn't read at slow speeds causing the ABS to kick in.
