SSM 523642024-04-04. Service bulletin. STRUCTURE:BODY:DOOR; ELECTRICAL SYSTEM:SOFTWARE. 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.
