My ABS and traction control isn't working, I had the car scanned and there weren't any codes, and I changed the passenger front wheel bearing, everything is quiet now. Brake fluid is filled to the correct level. All I can think of is a broken wire to a speed sensor or the abs module is bad. Is there any other way of diagnosing either of the two besides inspecting the wires and just replacing the ABS module? Test light?

Please help.
