Brake / ABS warning lamp

Group,
I am wondering if any of you are aware of a problem in the newer Ram trucks (mine's an 03). Recently while driving, my Brake and ABS warning lamp came on and the speedo immediately dropped to Zero and stayed there..... Anyone have any idea what happened without getting plugged in to the OBDII?

Any input would be appreciated

Failure of the rear wheel speed sensor. Common problem - easy fix. If it's
still under warranty, you can go that route, or you can fix it yourself for
about $30. Unplug the electrical from the sensor, located on top of the
rear differential housing, then unbolt the sensor hold-down bracket. You'll
probably have to remove another nut and move the brake line out of the way
in order to remove the sensor. Put the new one in, bolt everything back
down, and re-install the electrical connector. Should take about 5 minutes.
