Hi, there is a speed sensor causing your problem which is the one on the top of the rear differential. Its the one that runs the speedometer, picked up by the abs module. The abs is disabled if the light is on, your brakes will stayed locked if you start to slide.
I'd start with replacing the rear speed sensor and see what happens. This should bring your speedometer back if nothing else. If you still have the other code coming back you'll have to replace the abs control module. That code is a direct internal failure of the control module, no diagnostics required.
