Finally got my scanner updated. Brought in a car that's had the abs light on for a while now. Rh rear wheel sensor. Took a look and the wires were broken... 2 of the clips holding the wire in place were disintegrated and over time the combination of flopping around and 250k kms of gravel roads destroyed the wire. The drivers rear had a broken clip as well. Easy fix, 10mm bolt holds the sensor to the backing plate, a few 12mm holds the wire to the body, it unplugs under the rear seat. The lights went out on the dash without needing to clear them with the scanner.
