Pinpoint Test X : The Side Obstacle Detection Control Module RH (Sod-R) Does Not Respond To The Diagnostic Scan Tool

WARNING: This page is about a different car, the 2018 Ford F-550 Super Duty, 2018 Ford F-450 Super Duty, 2018 Ford F-350 Super Duty, and 2018 Ford F-250 Super Duty. However, it is still accessible from the selected car via links, so may be relevant.

  1. X1 CHECK THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) VOLTAGE SUPPLY CIRCUITS FOR AN OPEN

    • Ignition OFF.

    • Disconnect: SODR C4484 (with LED rear lamps) or C461 (without LED rear lamps).

    • Ignition ON.

    • Measure:

      With LED rear lamps

      Ground

    Is the voltage greater than 11 volts? 

    Yes  GO to  X2
    No  VERIFY the BJB fuse 34 (10A) is OK. If OK, REPAIR the circuit. If not OK, REFER to the OEM Wiring Diagrams to identify the possible causes of the circuit short.
  2. X2 CHECK THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) GROUND CIRCUIT FOR AN OPEN

    • Ignition OFF.

    • Measure:

      With LED rear lamps 

      Positive Lead Measurement / Action Negative Lead
      C4484-9
      GFD200490Courtesy of FORD MOTOR COMPANY
      Ground

      Without LED rear lamps 

      Positive Lead Measurement / Action Negative Lead
      C461-6

      Ground

    Is the resistance less than 3 ohms? 

    Yes  GO to  X3
    No  REPAIR the circuit.
  3. X3 CHECK THE MS-CAN (MEDIUM SPEED-CONTROLLER AREA NETWORK) CIRCUITS BETWEEN THE SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) AND THE GWM (GATEWAY MODULE A) FOR AN OPEN

    • Measure:

      With LED rear lamps 

      Positive Lead Measurement / Action Negative Lead

      C2431-22

    Are the resistances less than 3 ohms? 

    Yes  GO to  X4
    No  REPAIR the circuit in question.
  4. X4 CHECK FOR CORRECT SODR (SIDE OBSTACLE DETECTION CONTROL MODULE RH) OPERATION

    • Ignition OFF.

    • Disconnect and inspect the SODR connector and related in-line connectors.

    • Repair:

      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary

    • Reconnect the SODR connector and related in-line connectors. Make sure they seat and latch correctly.

    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable Technical Service Bulletins (TSBs). If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no Technical Service Bulletins (TSBs) address this concern, INSTALL a new SODR. Refer to: Side Obstacle Detection Control Module .
    No  The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
