this is my first time on the tdr roundtable, hope i am not in the wrong spot? any way, i have the same problem on my 2000 4x4 2500 the abs and brake lights came on a few days ago. i discovered that the abs pump would not quit running, i pulled the abs fuse which was the only way it would stop even with the ignition off. i have since checked my front wheel sensors and the rear wheel sensor on the diff. no problems found. i have ask several parts suppliers what they thought the problem could be with no positive results. based on what i have read on this sight i will try a new abs controller.
