The codes suggest RF sensor & LF pulser.
I checked manual and there is a long diagnostic procedure. You can check resistance of sensor. It should be 450-2000 ohms.
On other ABS system, I had success w/ simply removing the sensor, cleaning sensor, and cleaning pulser by stuffing rag down sensor hole to push against pulser (tone ring) and rotationg wheel. Dirt/grime on the sensor and pulser can cause poor signal and set a code. Worth a try.
For details you need the shop manual I mentioned.
