Abs/brake light is on.I replaced the Abs pump Control Module Still Have the code # 68 Motor Circuit Malfunction.I was told it could be a connector or the hydraulic control unit (HCU). I erased it Drove Down the Road, Abs/Brake Light Comes back on. Same code is read ! My Question Does Anyone Know How To Fix Or Correct This Problem or Code.

There is a tsb on this and the HCU has to be replaced then after that a scanner has to put the correct gear ratio along with tire size iin to fix this. I'm not sure if a dealer will do this at this point due ot age. Also it only does it while cruise control is engaged from 74-76 mph. See pic for qualifying vehicles.
