Pinpoint Test I : The SCCM Does Not Respond To The Scan Tool

WARNING: This page is about a different car, the 2016 Lincoln MKS. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: Failure to disconnect the battery when instructed results in false resistance readings. Refer to Battery, Mounting and Cables .

  1. I1 CHECK THE SCCM VOLTAGE SUPPLY CIRCUITS FOR AN OPEN

    • Ignition OFF.
    • Disconnect: SCCM C2414B (Adjustable steering column).
    • Ignition ON.
    • Measure the voltage  between:
      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C2414A-5 SBP23 (WH/RD) - Ground

    • Measure the voltage  between:

      Adjustable steering column 

      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C2414B-8 SBP24 (VT/RD) - Ground

    Are the voltages greater than 11 volts? 

    Yes  GO to  I2.
    No  VERIFY the Body Control Module (BCM) fuses 23 (15A) and 24 (15A) are OK. If OK, REPAIR the circuit in question. If not OK, REFER to the OEM Electrical Wiring Diagram Introduction to identify the possible causes of the circuit short.

  2. I2 CHECK THE SCCM GROUND CIRCUITS FOR AN OPEN

    • Ignition OFF.
    • Disconnect: Negative Battery Cable.
    • Measure the resistance  between:
      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C2414A-2 GD375 (BK/BU) - Ground
    1. GFD87009Courtesy of FORD MOTOR COMPANY
    • Measure the resistance  between:

      Adjustable steering column 

      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C2414B-5 GD375 (BK/BU) - Ground
    1. GFD87011Courtesy of FORD MOTOR COMPANY

    Are the resistances less than 3 ohms? 

    Yes  GO to  I3.
    No  REPAIR the circuit in question.

  3. I3 CHECK THE HS-CAN CIRCUITS BETWEEN THE SCCM AND THE DLC FOR AN OPEN

    • Measure the resistance  between:
      Positive Lead Negative Lead
      Pin Circuit Pin Circuit
      C2414A-1 VDB04 (WH/BU) C251-6 VDB04 (WH/BU)
      C2414A-14 VDB05 (WH) C251-14 VDB05 (WH)
    1. GFD89616Courtesy of FORD MOTOR COMPANY

    Are the resistances less than 3 ohms? 

    Yes  CONNECT the negative battery cable. GO to  I4.
    No  REPAIR the circuit in question.

  4. I4 CHECK FOR CORRECT SCCM OPERATION

    • Disconnect all the SCCM connectors.
    • Repair:
      • corrosion (replace connector or terminals - clean module pins)
      • damaged or bent pins - replace terminals/pins
      • pushed-out pins - replace pins as necessary
    • Connect all the SCCM connectors and make sure they seat correctly.
    • Verify the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, discontinue this test and follow TSB instructions. If no TSBs address this concern, INSTALL a new SCCM. REFER to Steering Column Switches .
    No  The system is operating correctly at this time. The concern may have been caused by a loose or corroded connector.
