There is no rear ABS wheel speed sensor the system uses the vehicle speed sensor to work as the rear ABS sensor. Here is an ABS wiring diagram so you can see what I am talking about.

So I would clear the codes and try it again.

Here is how

Please let us know if you need anything else to get the problem fixed.

What I did on suburban 2002 for ABS light not goes off is I just removed the negative cable of the battery and turn on the ignition key for 10 minutes. After I fixed back the batt. Cable I start it and the ABS light goes off.
