SSM 52364	2024-04-04. Service bulletin. 2021-2023 Bronco vehicles built on or before 9-Jul-2023 may have new version software in their driver door module (DDM) and passenger door module (PDM) that contains noticeable enhancements to the window short drop operation. This software level can be identified in the DDM and PDM as Software Part Number MU5T-14C064-CR or later. This software was released via a software update delivered over-the-air (OTA) starting in September 2023 if the vehicle's connectivity was enabled in the vehicle settings. Vehicles with this new software will exhibit a short drop event to all door windows anytime the vehicle is unlocked using the remote keyless entry (RKE), accessory keyless entry keypad, or the interior door unlock switch. The short drop function will return to the UP position when a lock input is received from these same inputs. For vehicles equipped with passive entry, a short drop event will not activate when a door is unlocked by placing a hand on an exterior door handle. 2023-2024 Bronco vehicles built on and after 10-Jul-2023 received this software from the factory.
SSM 52354	2024-04-04. Service bulletin. Some 2023 Bronco vehicles may exhibit diagnostic trouble code (DTC) U2101 stored in accessory protocol interface module (APIM) and/or telematics control unit (TCU) after TCU module programming with no additional symptoms present. This may be due to the TCU configuration. To correct the concern, download and run the TCU-Telematics Control Unit (TCU) Module Configuration application using Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 14F546 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.

To correct the concern, download and run the Transport and Factory Mode Deactivation app: under HS1 modules select BCM > Transport and Factory Mode > Download > Run. When the pop-up message appears for Change Vehicle Mode - Transport/Factory/Normal Mode, press OK. This will proceed to the Transport and Factory Mode Deactivation screen, select Unlock Vehicle Connectivity Settings (21 MY + Vehicles). A pop-up message appears noting Vehicle Is Now In Normal Mode, select OK. This will return to the Transport and Factory Mode Deactivation screen, select Exit.

SSM 52036	2023-11-09. Service bulletin. Some 2021-2023 Bronco vehicles equipped with 4x4 with part time engagement may exhibit a condition of the vehicle being stuck in neutral tow mode. This may be due to a concern with the all-wheel drive (AWD) module. Make sure the proper procedure is being followed to exit neutral tow mode by referring to the Owner's Manual > Towing Your Vehicle > Recreationally Towing Your Vehicle. Make sure the vehicle's battery is fully charged and then diagnose all diagnostic trouble codes (DTCs) in the AWD module. Refer to Workshop Manual (WSM), Section 307-07A. If diagnostics do not resolve the concern or there are no DTCs present in the AWD module, replace the transfer case and the AWD module. Refer to the appropriate section of the WSM. Once repair is complete, verify the vehicle's ability to successfully enter and exit neutral tow mode by cycling the vehicle in and out of neutral tow mode a minimum of two times, allowing the vehicle to enter sleep mode (key-off for at least 5 minutes) between each cycle. Inform customers that Ford is currently working on a software update to address this condition without a need

Some 2021-2023 Ford and Lincoln vehicles equipped with SYNC 4 may exhibit the navigation feature in the center display screen only displaying imperial units and not being able to change to metric. This may be due to the software level of the SYNC module (APIM). This issue does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that engineering is currently working on a solution for this condition and will be released via Ford Power-Up software updates delivered over-the-air (OTA) expected in September 2023. Software will update automatically if vehicle connectivity is enabled in the vehicles settings. Schedule a service visit for customers who have disabled vehicle connectivity or who report that they did not receive the update in September 2023. Monitor OASIS for additional information.
