2021 Ford Edge SE, 4WDSECTION Pinpoint Test AF : DTC B272C
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. WARNING: Incorrect repair techniques or actions can cause an accidental Supplemental Restraint System (SRS) deployment. Never compromise or depart from these instructions. Failure to precisely follow all instructions could result in serious personal injury from an accidental deployment.

  2. AF1 CHECK THE SCME (FRONT SEAT CLIMATE CONTROL MODULE) FOR ON-DEMAND DIAGNOSTIC TROUBLE CODES (DTCS)

    • Using a diagnostic scan tool, perform the SCME self-test.

    Was DTC B2729 or B2730, retrieved on-demand during the self-test? 

    Yes  For DTC B2729, GO to Pinpoint Test AJ . For DTC B2730, GO to Pinpoint Test AK 
    No  GO to  AF2

  3. AF2 MONITOR SCME (FRONT SEAT CLIMATE CONTROL MODULE) BLOWER MOTOR TEMPERATURE PARAMETER IDENTIFICATIONS (PIDS)

    • Using a diagnostic scan tool, monitor the following SCME Parameter Identifications (PIDs):

      • Passenger Cushion Thermal Electric Device (TED) Temperature (PCSHTMP)
      • Passenger Back (TED) Temperature (PBKTMP)
      • Seat cushion thermal electric device temperature (CSHTEMP)
      • Seat back thermal electric device temperature (BKTMP)

    • NOTE: Make sure the temperature of the climate controlled seats has stabilized before monitoring the Parameter Identifications (PIDs). Not allowing stabilization can cause incorrect readings and lead to incorrect identification of components that are not faulty.

      Monitor blower motor temperature Parameter Identifications (PIDs) with the climate controlled seats OFF. Compare the PID values of the driver seat to those of the front passenger seat, this can help identify if there is a concern with the driver seat cushion or backrest PID value readings.

    Are both driver seat blower motor temperature Parameter Identifications (PIDs) within 10 ° C (18 ° F) of the ambient temperature? 

    Yes  GO to  AF3
    No  If the driver seat cushion PID varies 10 ° C (18 ° F) or more from ambient temperature, GO to  AF16. If the driver seat backrest PID varies 10 ° C (18 ° F) or more from ambient temperature, GO to  AF32

  4. AF3 CONFIRM THE FAULT IS IN THE SEAT CUSHION OR THE BACKREST

    • Ignition OFF.

    • Start the engine.

    • NOTE: A crushed seat cushion foam pad may be the cause of the fault. It may be necessary to sit on the seat or place something of reasonable size and weight on the seat to recreate the fault.

      After cycling the ignition and with the engine running, set the driver seat to high heat. Allow the seat to heat for at least 15 minutes while monitoring the blower motor temperature Parameter Identifications (PIDs) of the driver seat.

    Do the driver seat cushion blower motor and backrest blower motor Parameter Identifications (PIDs) vary more than 60 ° C (108 ° F) from each other? 

    Yes  If the driver seat cushion PID is 60 ° C (108 ° F) hotter than the backrest PID, GO to  AF5. If the driver seat backrest PID is 60 ° C (108 ° F) hotter than the cushion PID, GO to  AF20
    No  GO to  AF4

  5. AF4 CHECK THE BLOWER MOTOR COOLING PERFORMANCE

    Did the blower motors pass the component test? 

    Yes  The DTC may have been set by extreme cabin temperatures or excessive sunload on the seat causing the system to enter recovery mode. Occupant size and weight characteristics can also be a factor. CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test. TEST the system for normal operation. If a concern cannot be found or duplicated, RETURN the vehicle to the customer.
    No  CHECK the affected seat cushion or backrest for correct installation of the climate controlled seat components (blower motor, air ducts and foam pad). CHECK for airflow restrictions (blower motor inlets and outlets, filters and ducts) and REPAIR as needed. CHECK for an intermittent wiring fault. REPAIR as needed. CLEAR the Diagnostic Trouble Codes (DTCs). REPEAT the self-test.
