The DSC control module may have failed. It sends the road speed signal to the instrument cluster.

Mine is older (1995) but I had a bad left rear ABS sensor that killed the speedo, odo, cruise, windshield wipers - everything that had a "speed" input plus the airbag light came one. A new sensor fixed all of it.
IIRC - The newer models take readings off both rear wheels. And maybe the front wheels too. Google it.
Before diving under the dash, figure out what is controlled by which wheel. Try swapping or replacing one. (A 5mm hex and a few minutes work.) Grady
