2nd Gen Non-Engine/Transmission What would cause the ABS motor to run continuously?

[Allnew2Me]

I got a call from a friend today with a 2001. 5 2500 auto. His ABS motor is running all the time, even with the truck turned off. The only way he can stop it is to pull the relay. He checked for codes, none, checked the ABS connector at the diff, all okay there, no blown fuses, any ideas?





UPDATE- with a search I think I found the answer, it seems to be the ABS controller that fails in this situation.

Had a similar thing with my 04. Dodge dealer replaced the "ABS module". Said it was internally shorted. All better now.
