there should be a sensor on the rear end (pumpkin) on the top, Its for ABS and effects the speedometer. replace it, part at Dogde dealer, and have autozone clear the codes on the computer.

Don't bother with the dealer.... With the ABS light in combination with the BRAKE light means you have a speed sensor problem... I had the same problem on a 99 Dakota Sport (manual transmission). I was also having a problem with the speedometer working till it gets to 25-30 mph and the engine idle speed usually drops off and the engine shuts off when you stop...

Replace the speed sensor on top of the rear differential... To reset the computer disconnect the negative battery cable, turn the ignition key to the on position (don't turn to start position), wait 30 seconds and push the brake pedal down to drain the complete charge off the computer. Reconnect the battery cable and you're ready to go... Don't worry if the lights don't go off right away. You may need to let the computer recalibrate itself. Just test drive it. The lights should reset by the time you get out of the driveway... You should notice right away that the idle speed and speedometer have already improved...

Good luck....

The reason for the speedometer and abs problem is a bad rear abs speed sensor located on the rear differential

ABS Parking Brake light, and speedometer are all related.  Dodge trucks are notorious for getting moisture in the ABS module plug.  To fix - simply unplug the ABS module that's located directly behind the battery. Use an air hose and blow out the water/moisture from the plug and connector.  This fixed my problem.
