I lost my speedo. Odometer works, brake light and abs are on. No speedometer. Floats between 0-15 mph at high speeds. I've replaced the RAWL sensor in back and the VSS. Wires look fine. Tested RWAL wires where they dissappear in the harness above the drivers side wheel. They test fine. I get around 1800 ohms on the RAWL sensor. Visually inspected the VSS wires, they look good.

Any other suggestions, I'm at a loss, I've searched the forums for hours. I have an appt. at the ******* to read my abs codes.

What triggers the RWAL sensor? I do have something up with the rear axle, I can feel it hop when I have a load on and am backing up. Is there something in the pumpkin that could have gone bad therefore not triggerring the RWAL sensor?

Was the sensor damaged? Maybe it's time to pull cover and take a look at the gears and sensor ring for damage.

sensor was not damaged, but you may have answered my question. What is the sensor ring?

The sensor ring is attached to the ring gear/carrier and the sensor reads the marks on it and teh computer calulates speed from that.

(Finally figured this out...)

Had the same "permanently" glowing ABS and Brake light indicators...plus...a sporadic speedometer and glitchy windshield wipers... spent about 30min under the hood gently pushing/pulling on wires and lucky enough I just so happened to tug on a wire cluster which led to a loose and slightly corroded ground screw! I uploaded a photo for better reference...you'll notice its the ground screw touching the tip of the orange clamp (on driver side fender rail).
