I have a 2002 5.9L Dodge Durango SLT with 4WD. I had an ABS/Brake error light which I've repaired before and knew it was the PC board that plugs into ABS module, but could not find one to purchase nor find someone to repair error code #68 on the board. I was forced to buy a rebuilt assembly to get the board and fix my problem. The rebuilt unit I bought came with the PC board, control module and hydraulic pump assy. I did not need to replace the control module and hydraulic pump to repair my problem and now have this extra assembly. I voided my warranty because I removed the needed PC board and therefore can not offer a warranty to buyer, but this part was tested good by the rebuilder with a 1 year warranty so I feel it will be operational and reliable.
