Various 2020\-2026 Ford and Lincoln vehicles equipped with blind spot information system \(BLIS\) may experience an inoperative blind spot monitoring with a "Blind Spot System Fault" message displayed in the instrument panel cluster \(IPC\). This may also be accompanied by diagnostic trouble codes \(DTCs\) B118C:11 and/or B118C:15 stored in the driver door module \(DDM\), and/or B118D:11 and/or B118D:15 stored in the passenger door module \(PDM\). This may be due to the wiring connector from the mirror to the BLIS module. If diagnostics lead to an internal mirror wiring harness fault, a new lower level BLIS light pigtail is now released for service. It is not necessary to replace the exterior mirror assembly. Use part number SC3Z\-14A411\-B to resolve the concern.
- [SSM 54589](/bulletins/11029595.md), 2026-03-04, Other: ELECTRICAL SYSTEM. Some 2019\-2024 Ford and Lincoln vehicles equipped with SYNC3 may experience various connectivity concerns with The Ford App Lincoln App including but not limited to: missing activation prompt pop\-upon the vehicle's center display screen when attempting to activate vehicle through The Ford App Lincoln App, incorrect location global positioning system GPS reported through The Ford App Lincoln App, problems with remote commands being performed through The Ford App Lincoln App and or incorrect data information reported on The Ford App Lincoln App. These symptoms will be accompanied by diagnostic trouble code DTC B156D 89 in the TCU. This may be due to the accessory protocol interface module APIM software. To correct the condition, update the APIM software.
- [SSM 54601](/bulletins/11029052.md), 2026-02-27, Service bulletin: ELECTRICAL SYSTEM; STRUCTURE:BODY; UNKNOWN OR OTHER. Ford and Lincoln vehicles equipped with wired keyless entry keypad systems and accessory wireless keyless entry keypad systems may or may not come with a wallet card containing the master code. Unlike the integrated wired keypad, the accessory wireless keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool or from the label printed on the body control module \(BCM\). The Factory Keyless Entry Code application within the diagnostic scan tool will not provide an applicable master code for the accessory wireless keypad. If the wallet card for an accessory keypad is not available, the "Wireless RF Keypad Diagnosis Guide" can be referenced and provides direction on how to retrieve the master code. This guide is located under the Workshop Manual tab \> Accessories \> Installation \> Wireless RF Keypad Diagnosis Guide \> PPT C \> Step C2.\<br /\>\<br /\> Note: The only available keypad for some vehicles from the assembly plant is the accessory wireless keyless entry keypad. The integrated wired keypad cannot be installed on vehicles not equipped from the factory with a wired keyless entry k

- [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.
- [TSB 25\-2322](/bulletins/11020894.md), 2025-07-24, Service bulletin: POWER TRAIN; ELECTRICAL SYSTEM.

This condition does not affect vehicle drivability or durability.
- [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.
