Started car car this noon, ABS.PSM failure warning is lit up, drove about 10 miles, operation is normal, brakes, etc

any ideas?

A tech can probably query the ABS/PSM system for any errors and make an informed diagnosis. Absent a professional tech's diagnosis my WAG is a wheel speed sensor is bad. By "bad" I mean the sensor could really be bad, have failed, or the wiring harness may have experienced a broken wire, or just a speed sensor connector could be "loose"

If you had any work done on the car recently and in the area of the wheels/tires I'd probably suspect a loose connector..
