BlackTitanium Posted July 19, 2022 Report Share Posted July 19, 2022 Hello all and forgive me if this has been gone over. I searched and probably overlooked it. when I bought the vehicle I noticed the next day the heated and cooled seats up front wouldn’t work. Rear seat heat works fine but up front has nothing. Took it back to the dealer they said it was probably the “DCSM” and they were going to order the part and replace it. Fast forward and it’s been over a month and they said they still do not have the part. I’m starting to wonder if they are just trying to wait me out and see if I’ll say screw it and move on. my actual question is: https://www.getoemparts.com/oem-parts/ford-module-seat-heater-control-bu5z14c724a?c=az0x Is this the part that they are referring to that needs replaced? Or is there something else I’m looking for? They said it was under the pass seat and controlled both sides. thank you for any help. Quote Link to comment Share on other sites More sharing options...

Haz Posted July 21, 2022 Report Share Posted July 21, 2022 (edited) It sounds as though the dealer is not a Ford dealership, which I expect would perform diagnostic testing to ensure the part was actually faulty before they ordered its replacement. The following description of how the heated/cooled seats operate is from the 2016 Edge Workshop Manual. Where acronyms exist in the text, such as SCME, (which designates the Front Seat Climate Control Module which the dealer should be referring to), if you put your cursor over the acronym, its meaning should show up on your computer screen... Good luck! Climate Controlled Seat Operation The driver and passenger climate controlled seat buttons are selected from the FCIM and FDIM (touchscreen). The climate controlled seat system functions independently from the vehicle's climate control system. The seat cushion and backrest are each equipped with a blower motor assembly. As cabin air is drawn through each blower motor, a Thermo-Electric Device (TED) heats or cools the air, which is then directed into the foam pad where it is distributed along the surface of the cushion and backrest of the seat. Once the system is activated, the SCME uses a set of flexible algorithms to control the heating/cooling modes and the blower speed dependent on the commanded climate controlled seat settings. The SCME monitors seat cushion temperature while it supplies voltage and ground to both blower motors. The SCME also supplies a variable voltage signal to control the blower speed. Cabin air enters the blower through an integrated filter attached to the blower motor housing. Heated or cooled air exits the blower motor and flows through the foam pad. Climate Controlled Seat Heating Characteristics In heat mode, the blower motor can add up to 40–60° C (72–108° F) to the ambient inlet air temperature. The system control settings are indicated next to each climate controlled seat heat switch button on the touchscreen. The first setting is HIGH (3 indicators), the second setting is MED (2 indicators) and the third is LOW (1 indicator) then OFF (no indicators). When heating, the SCME varies the speed of the blower motors and the duty cycle of the integral Thermo-Electric Device (TED) in order to reach and maintain the desired temperature determined by the system control settings. Climate Controlled Seat Cooling Characteristics In cool mode, the blower motors can remove up to 8° C (14° F) from the ambient air temperature entering the system. The system control settings are based on the 3 indicators next to each climate controlled seat cool switch button on the touchscreen. The first setting is HIGH (3 indicators), the second setting is MED (2 indicators) and the third is LOW (1 indicator) then OFF (no indicators). When cooling, the SCME maintains a constant blower motor speed and a constant Thermo-Electric Device (TED) supply voltage (duty cycle is determined by the switch setting) in COOL mode. Climate Controlled Seat Recovery Mode NOTE: The presence of overtemperature faults (Diagnostic Trouble Codes (DTCs) B2729, B2730, B272A and B272B) can be induced by incorrectly operating the climate controlled seat system after an initial heat setting has been attained. If a heat setting is repeatedly turned off and on in an attempt to increase the seat temperature or repeatedly toggled between heat and cool modes, an overtemperature condition can result and the Diagnostic Trouble Codes (DTCs) may be set. If the temperature of one of the blower motors rises above 110° C (229.8° F) in the heat mode or 65° C (148.9° F) in the cool mode for more than 4 seconds, the SCME records an over-temperature DTC , removes voltage from the Thermo-Electric Devices (TEDs) (part of the blower motor assembly) and goes into recovery mode (blower only) for 30 seconds to cool down the blower motor. The same occurs if a temperature difference of 60° C (108° F) or greater is detected between the backrest and cushion blower motors on either front seat. The SCME continues to monitor the blower motors while in recovery mode. If the temperature of the Thermo-Electric Devices (TEDs) do not drop to 105° C (220.8° F) in the heat mode or 60° C (139.9° F) in the cool mode after 30 seconds, the system continues to cool the blower motors in recovery mode for up to 5 minutes. If the Thermo-Electric Devices (TEDs) cool down after 30 seconds, but before 5 minutes (checked at 4 second intervals), the system is operating normally. An over-temperature DTC is still recorded even if the system recovers and is operating normally. This is more likely to occur during extreme cabin temperatures with significant seat back sun load. If the system does not recover within 30 seconds in heat mode or within 5 minutes in cool mode, the SCME disables that seat (fault mode) and remains off until the ignition is cycled. Also, if the SCME detects a temperature differential fault twice during the same ignition cycle, the SCME disables the seat. When a fault causes a shutdown, the climate controlled seat indicators turn off and that seat is not operational until the next ignition cycle. Remote Start Climate Operation Different climate control modes/preferences can be selected when the vehicle is started using the remote start feature. This can be accessed through the message center. For additional information on how to set the remote start preferences, refer to the Owner's Literature. When the driver seat and/or passenger seat is set to AUTO mode, the driver/passenger heated/climate controlled seat activates in full heat mode when the outside temperature is less than 0° C (32° F) and full cool mode (climate controlled seats only) when outside temperature is greater than 27° C (80° F) any time the vehicle is started using the remote start feature. No heated/climate controlled seat adjustments are recognized during remote start operation. Once the ignition is cycled ON, the heated/climate controlled seat turns off. SCME Location Beneath Passenger Seat Front Seat Climate Control Module [SCME] Removal NOTE: This step is only necessary when installing a new component. NOTE: The PMI process must begin with the current SCME installed. If the current SCME does not respond to the diagnostic scan tool, the tool may prompt for As-Built Data as part of the repair. Using a diagnostic scan tool, begin the PMI process for the SCME following the on-screen instructions. NOTE: The SCME outboard mounting tab is located under the front seat front shield. Remove the screws and position the SCME aside. Remove the SCME . Release the locking wedges. Disconnect the electrical connectors. Installation To install, reverse the removal procedure. NOTE: This step is only necessary when installing a new component. Using a diagnostic scan tool, complete the PMI process for the SCME following the on-screen instructions Please notice that a new SCME cannot be installed and be expected to function without the original module's digital code being programmed into the new module after its installation. If the original code is not retrieved before the SCME is replaced, it is still possible to obtain the digital coding via so-called 'As Built Data' which is readily available through several sources. An appropriately equipped owner -- with computer awareness, a laptop computer, no-cost temporarily licensed Forscan software, and an OBDII adapter -- can cautiously accomplish this new-SCME programming task, referred to above as the PMI process. Listings on Ford's online parts site show the build date of the vehicle determines which SCME is needed Edited July 21, 2022 by Haz 1 Quote Link to comment Share on other sites More sharing options...

Haz Posted July 21, 2022 Report Share Posted July 21, 2022 (edited) FordParts.com images for potential part number reference to Edge Build Date... Edge Usage 01-19-2015 - 07-20-2016, Edge 2015-, With Pass Heated And Cooled Seat, With Drivers Heated And Cooled Seat Edge Usage 07-20-2016 - 09-06-2018, Edge 2015-, With Pass Heated And Cooled Seat, With Drivers Heated And Cooled Seat Ford's FordParts.com site has a VIN-based search function that would be helpful toward identifying the appropriate part... As a double-check, you could take a camera-phone photo beneath the forward underside of the passenger seat to determine the current SCME's part number. Then, if the dealer hasn't obtained the replacement part yet, you could passive-agressively ask them what part number it was that they ordered. Good luck!

CARR142 Posted July 22, 2022 Report Share Posted July 22, 2022 (edited) Also check the connector to the module, the Black wire, (ground), may have burnt the connector due to over heating at that pin connection. Common Problem. Edited July 22, 2022 by CARR142 Addendum Quote Link to comment Share on other sites More sharing options...
nlitend1 Posted November 11, 2022 Report Share Posted November 11, 2022 An interesting read and video, thank you all for the info! Watching the video there is only one wire burnt, the ground. On our 2017 Edge there is actually 2 wires side by side (2nd occupies the empty slot on video) that are burnt. Both the same color. I am assuming they are both grounds, perhaps an attempt to upgrade a known issue at Ford? Neither seats work in our car, heat or cool. Fuse is good. Is the burnt connector the real issue? Not having good contact now? Quote Link to comment Share on other sites More sharing options...
