2004 1/2 --- rx330---- 30K we had the same problem VSC light on, ABS light on and INFL light on and flashing we brought the vehicle in for a exhaust manifold recall and when the car was returned about a day later the three lights came on. Brought it back to the dealer and they found the right front speed sensor was faulty, they replaced for $500. Two days later the lights returned for a day and them went out again and stayed off. We brought the car back anyway and there tech investigated further and found the wiring harness that feeds the right front wheel sensor to be chaffed. he asked if the vehicle had been in an accident (which it had about a year earlier in the right front) he said that it appeared that the autobody shop had poorly repaired the wire that was damaged in the accident and not properly secured the wire to avoid additional damage. they repaired the damage and the lights have not returned. a note the speed sensor itself was probably ok and the problem went away briefly because in changing the sensor the wires were shifted and need time and travel to begin shorting again.
