Hi there. Different expert here.63, 65 and 78 are generic ABS codes retrieved using a generic scan tool. To get any degree of accuracy, Dodge ABS diagnostics must be performed with the aid of a DRB-III scan tool.The symptoms related to those generic codes point to a bad hydraulic control unit (CAB). Here are the diagnostic procedures:REAR RESET SWITCH CLOSED - EBC 2When Monitored and Set Condition:REAR RESET SWITCH CLOSED - EBC 2When Monitored: CAB not in the antilock pressure control mode.Set Condition: Reset switch voltage low and the when monitored conditions have beensatisfied for over 200 consecutive controller checks spaced 5 milliseconds (ms) apart (1.0second total).POSSIBLE CAUSESREAR SOLENOID DTC(S) PRESENTHCU 4-WAY HARNESS OR CONNECTOR DAMAGEMECHANICAL BRAKE CONCERNHCU INTERNAL CONCERNTEST ACTION APPLICABILITY1 Ignition on, engine not running.With the DRBIIIt, read DTC’s.Are there any DTC’s displayed for the Rear Solenoid Valves?AllYes - Perform the appropriate diagnostics test for the displayed DTC’s.Perform ABS VERIFICATION TEST - VER 1.No - Go To 22 Turn the ignition off.Disconnect the HCU harness connector.Note: Check connectors - Clean/repair as necessary.Inspect the HCU harness and connector for damage.Is there any HCU connector, terminal or harness damage?AllYes - Repair the HCU 4-way harness or connector as necessary.Perform ABS VERIFICATION TEST - VER 1.No - Go To 33 Road test the vehicle and check mechanical brake operation.Check whether brakes apply and release OK.Is there a mechanical brake operation concern?AllYes - Repair the mechanical brake concern.Perform ABS VERIFICATION TEST - VER 1.No - Replace the Hydraulic Control Unit in accordance with theService Information.Please let me know if you have any other questions.Best Regards.
