Some 2021\-2024 F\-150 vehicles equipped with a B\&O audio system \(minor feature code IDBBQ\), and various 2021\-2024 Ford and Lincoln vehicles equipped with a B\&O audio system may exhibit a pop noise and/or static in the speakers at start up that cannot be turned down or off using the audio system controls. To confirm a vehicle is built with a certain minor feature code, review the build information by double\-clicking the vehicle identification number \(VIN\) in the upper left corner on Professional Technician System \(PTS\). This may be due to software in the digital signal processing \(DSP\) module. To correct this condition, reprogram the DSP module to the latest software level using the Ford Diagnosis and Repair System \(FDRS\) scan tool. For claiming, use causal part 18B849 and labor operations 12651D and 12651D4. - [SSM 54116](/bulletins/11021803.md), 2025-08-12, Service bulletin: UNKNOWN OR OTHER; ELECTRICAL SYSTEM. Various 2019\-2024 Ford and Lincoln vehicles equipped with SYNC 3 may experience a partially or fully black center display screen at start\-up using Apple CarPlay or Android Auto. This does not affect rear camera operation. This may be due to interference from the phone being connected into the media hub using a universal serial bus \(USB\) cable during SYNC system boot up. To correct his condition, advise the customer to disconnect the USB cable from the phone. If the center display screen displays normally, reconnect the phone. If the concern persists, disconnect the phone from the USB cable, cycle the ignition off and open the driver's door so the interior lights come on. Close the door, start the vehicle and wait for the center display screen to boot up past the start\-up animation and display the home screen, then reconnect the phone using the USB cable. If the concern persists after this procedure, follow normal Workshop Manual diagnostics for a blank screen concern. - [SSM 53966](/bulletins/11019702.md), 2025-06-24, Service bulletin: ELECTRICAL SYSTEM; UNKNOWN OR OTHER. Some 2021\-2025 Ford/ Lincoln vehicles equipped with SYNC4 may not be able to perform an update to the accessory protocol interface module \(APIM\). This may be due to the software in the APIM. Ford Engineering has de\-activated the ability to update these SYNC4 APIM modules as applicable, and the Ford Diagnosis and Repair System \(FDRS\) will not present an update for the APIM module. Some existing directed repairs may be impacted, check Professional Technician System \(PTS\) before attempting any specific technical service bulletin \(TSB\)/special service message \(SSM\) and check field service action \(FSA\) landing pages before attempting any FSA repairs. For any vehicle repairs requiring a software update that includes an APIM update in the programming sequence, if the 5\-digit product code for the APIM software is equal to or lower than 23187, do not attempt to update affected modules at this time. To determine the 5\-digit product code for the APIM software on the vehicle, while the vehicle center display screen is powered up with ignition in run or accessory, go to Settings \> General \> About SYNC. - [SSM 52307](/bulletins/10250852.md), 2024-03-05, Service bulletin: ELECTRICAL SYSTEM. Some 2020\-2023 Ford and Lincoln SYNC3 equipped vehicles may experience an inaccurate notification in the FordPass®/LincolnWay® app indicating Vehicle Has Entered Deep Sleep Mode. Vehicle Has Entered Deep Sleep Mode message is expected if the vehicle has not been started for 14 consecutive days, battery voltage is at/below 9.5 volts or the body control module \(BCM\) 12 volt battery state of charge \(SoC\) drops below 50%. If the vehicle is going into deep sleep due to one of these conditions, follow normal Workshop Manual \(WSM\) Section 414\-01 procedure to correct the concern. If the vehicle is going into deep sleep outside these conditions, this may be due to the telematics control unit \(TCU\) software. To correct this condition, follow the Service Procedure to update the TCU to the latest software. For claiming, use causal part 14G229 and applicable labor operations in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.
