Default Possible ABS module failure?

Occasionally while driving, and sometimes on startup, my odometer and trip read ----.-/------, my speedometer drops to zero and my brake and ABS lights turn on.

If it's the V70XC, I'd have no idea. If it's a late model RWD 240/740/940, then it's likely the speed sensor in the rear axle, that runs both the speedo/odo and one of the 3 circuits in the ABS system. Bad sensors on the diff cover, or bad wiring to it, would give you those symptoms.
