- [SSM 52476](/bulletins/10254138.md), 2024-05-03, Service bulletin: EQUIPMENT. All accessory stick\-on keyless entry keypads come with a wallet card containing the master code. If the accessory keypad was factory installed, this card will be placed in the glove box and should be handed to the vehicles owner during initial delivery. Unlike the integrated \(wired\) factory keypad, the accessory keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool. If the wallet card for an accessory keypad is lost, follow these steps to recover the code. Dealer Key Code access is granted through the Dealer Program Enrollment System \(DPES\); dealership management can authorize users. The authorized user must go to FMCDealer.com \> Parts and Service \> Parts Product Line Information \> Keys/Entry Devices \> Aftermarket Keyless Entry Keypad Code Access. Follow the instructions on the screen to obtain the master code for the accessory keypad.
- [SSM 52385](/bulletins/10252646.md), 2024-04-04, Service bulletin: EQUIPMENT. Some 2024 Bronco vehicles equipped with a factory hard top build on 07\-Feb\-20204 and through 13\-Feb\-2024 may have a hard top rear cap that is difficult to remove. This may be due to a temporary production change to the bolts that were used to retain the rear cap to the body. These unique bolts have a yellow nylon locking material on the bolt threads that cannot be cleaned off. To correct this condition, replace all hard top rear cap to body bolts with the correct catalog replacements.
- [SSM 52370](/bulletins/10252634.md), 2024-04-04, Service bulletin: EQUIPMENT:ELECTRICAL:INFOTAINMENT:SOFTWARE; EQUIPMENT:ELECTRICAL:INFOTAINMENT. Some 2023\-2024 F\-150 and 2024 Bronco/Transit vehicles may exhibit Apple Carplay Bluetooth connectivity concerns. This may be due to the accessory protocol interface module \(APIM\) software. To correct this concern, perform a soft reset by pressing the Power and Seek Foward buttons for 5 seconds, or use the SYNC Module Reset function of the Ford Diagnosis and Repair System \(FDRS\). For claiming, use causal part 14G670 and applicable labor operations in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.
- [TSB 24\-2080](/bulletins/10252558.md), 2024-04-03, Service bulletin: STRUCTURE:BODY:ROOF AND PILLARS; STRUCTURE; EQUIPMENT. This article supersedes 23\-2024 to update parts list to include rivets. Some 2021\-2023 Bronco vehicles equipped with a factory soft top roof may exhibit a headliner that is detaching from the soft top material. This may be due to the factory installation process.
- [SSM 52328](/bulletins/10251947.md), 2024-03-20, Service bulletin: EQUIPMENT:ELECTRICAL:INFOTAINMENT:SOFTWARE; EQUIPMENT:ELECTRICAL:INFOTAINMENT. Some 2021\-2024 Bronco/F\-150, 2023\-2024 Escape/F\-Super Duty vehicles equipped with SYNC 4 may experience a concern during accessory protocol interface module \(APIM\) programming where the vehicle's center display screen indicates USB Error. This may be due to a lack of memory space available to perform the APIM software update. If it is a memory concern, the Ford Diagnosis and Repair System \(FDRS\) will provide an option to delete the voice application. Re\-enter the module programming and when prompted, do not select first option \- SYNC Module \(APIM\) Software Update, select the second option \- Delete Voice Application\(s\) From Module. Once deleted, run the SYNC Module \(APIM\) Software Update as directed, this will update the software and automatically reload the voice app. If the voice delete option is not available, continue with normal diagnostics in the Workshop Manual, Section 418.
- [TSB 24\-2040](/bulletins/10251465.md), 2024-03-07, Service bulletin: EQUIPMENT. Some 2021\-2024 Bronco vehicles may exhibit paint damage on the rear quarter panel due to contact with the soft top rear window. This may be due to a contact condition that can occur during extreme off\-road driving between the soft top rear window and the rear quarter panel. To correct the condition, follow the Service Procedure to modify the rear window.
- [TSB 24\-2032](/bulletins/10251460.md), 2024-03-07, Service bulletin: EQUIPMENT; STRUCTURE:BODY:TRUNK LID. Some 2021\-2023 Bronco vehicles built on or before 28\-Feb\-2023 may exhibit water entry into the rear trunk. This may be due to a lack of body seam sealer at the floor panel to trunk sheet metal joint. This repair procedure addresses water entry from underneath of the vehicle into the rear trunk area \(jack storage compartment\). This article does not apply if water is entering the vehicle from above the rear trunk area \(such as from the roof, rear window etc.\). To correct the condition, follow the Service Procedure to apply seam sealer to the forward trunk to floor panel sheet metal joint.
- [SSM 52225](/bulletins/10249780.md), 2024-02-06, Service bulletin: EQUIPMENT:APPLIANCE:TV/RADIO/SPEAKERS.

Function should return with a key cycle and the symptom may return within every 1\-20 additional key cycles. This may be due to the software within the audio digital signal processing module \(DSP\). To correct the condition, reprogram the DSP module to the latest software level using the Ford Diagnosis and Repair System \(FDRS\) diagnostic scan tool. For claiming, use causal part 18B849 and applicable labor operations in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.

When ordered, the DIO trailer tow package will ship to the dealership that will receive the vehicle so that installation can occur prior to customer delivery. Labor is included with the cost of the Ford Accessory DIO trailer tow package and must not be charged to Ford through warranty.

The prep kit can be identified on the window sticker as Soft\-Top, Cloth W/Prep Kit under the optional equipment/other heading. This is a normal condition and no repairs/upfitting should be performed. Do not submit a claim for this condition.
