- [SSM 55037](/bulletins/11035233.md), 2026-07-27, Service bulletin: UNKNOWN OR OTHER; ELECTRICAL SYSTEM; SEATS. Some 2018\-2024 Expedition and 2018\-2027 Navigator vehicles equipped with a rear seat entertainment system/Lincoln Play may experience various system concerns. Rear seat entertainment systems are not on a controller area network \(CAN\) and are not supported by the Ford Diagnostic and Repair System \(FDRS\). Certain system concerns may be resolved through software updates which will automatically download once each individual monitor is connected to Wi\-Fi. Diagnostic support for rear seat entertainment systems is provided by VOXX electronics. If necessary, contact the VOXX Customer Service Department at 1\-866\-869\-7888. If possible, record the device serial number by selecting the gear/Setup icon \> Settings \> Device and Software \> About. If the unit will not power up, the serial number is on a label on the back of the monitor. It is helpful to know the date the issue occurred, how long the monitors were on prior to the issue, what app/input/media was being used, and if the system software was recently updated prior to the concern starting.

- [SSM 54720](/bulletins/11031263.md), 2026-04-10, Service bulletin: ELECTRICAL SYSTEM; LANE DEPARTURE: BLIND SPOT DETECTION. 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 54592](/bulletins/11029081.md), 2026-02-27, Service bulletin: POWER TRAIN. For 20172026 vehicles equipped with a 10R transmission, a revision to the Road Testing Vehicle procedure has been made in the WSM, located in Section 307\-01 \> Diagnosis and Testing. This updated procedure improves the diagnosis of customer reported transmission concerns and aids in locating the proper root cause. During diagnosis and testing, details regarding whether the condition is more prevalent when the vehicle is hot or cold, throttle percentage at the time of occurrence, vehicle speed, the specific shift involved, and whether the issue occurs during transmission engagements \(N\>R, N\>D, R\>D, or D\>R\) should be noted. Engineering requests including these detailed operating conditions that will significantly assist with root cause analysis. Diagnosis, testing, and repair should use established labor times outside this article.
- [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 54555](/bulletins/11028797.md), 2026-02-12, Service bulletin: UNKNOWN OR OTHER; STRUCTURE:BODY; ELECTRICAL SYSTEM. Some 2020\-2022\-Corsair, 2021\-2023 Nautilus, 2020\-2024 Navigator/Aviator, and 2021\-2024 Mustang Mach\-E vehicles equipped with phone\-as\-a\-key may exhibit various phone\-as\-a\-key concerns with diagnostic trouble codes \(DTC\) U200D:15, U200E:15, U200F:15, B1589:31/49 through B1598:31/49, B1A56:31/49, B1D55:31/49, and/or B15A5:56 stored in the remote function actuator \(RFA\) module. If any of these DTCs are detected during diagnostics, clear the DTCs, reprogram the RFA to the latest software level and start a new Ford Diagnosis and Repair System \(FDRS\) session. Verify that DTCs are no longer present. If only the B1589:31/49 through B1598:31/49, B1A56:31/49, B1D55:31/49, and/or B15A5:56 DTCs return in the RFA after a self\-test, follow normal Workshop Manual \(WSM\) diagnostics in Section 419\-01. Repair as necessary outside of this article. For claiming, use causal part 14G617 and labor operations 12651D and 12651D4.
