Default Four Wheel Anti-Lock Braking System

I have a 2002 Ranger XLT 4x2 with 4wabs. The ABS light has been on since I bought it and I was wondering if the ABS trouble code is stored within the ECU? I know with the RABS you can ground a wire on the RABS II diagnostics connector to test for the code yourself. Is there any way to do this with the 4wabs setup?

No, it is stored in the 4WABS Module. Ford dealers and some independent shops have a diagnostic tool that can access the code through the Module Communication Network. An ordinary OBDII code reader cannot access trouble codes unless they are stored in the PCM.

Figures, I was hoping to avoid paying someone to pull the code. I appreciate all the help with my ABS.

Here are a couple of visuals you can do:

Check the condition of the wires to the front sensors. They each have an electrical connector below their respective headlight and then the wire runs back along the top of the frame rail before dropping down to the spindle.

Check the front sensors and tone rings for dirt or corrosion build up. For 4WABS 2WD Rangers, the tone rings are in the back side of the brake rotors. The sensors fit through holes in the steering spindles.
