# Service bulletin SSM 49759

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NEW VEHICLE DELIVERY HOLD \- Emissions Recall 26E04 Certain 2021\-2025 Model Year F\-150, Maverick, Mustang, Ranger, Expedition, Bronco Sport, Explorer, Bronco, Navigator, and Aviator Vehicles Powertrain Control Module Software Update
- [SSM 55028](/bulletins/11035267.md), 2026-07-28, Service bulletin: ELECTRICAL SYSTEM; UNKNOWN OR OTHER. Some 2021\-2024 Ford and Lincoln vehicles may exhibit an "Updating SYNC" message on the vehicle center display screen after an over the air \(OTA\) update. The message can be cleared from the center display screen and SYNC can be used normally, but it will re\-appear at every subsequent ignition cycle. Inform customers that engineering is currently working on a software update solution for this condition to be delivered OTA expected in late Q3 2026. Software will update automatically if vehicle connectivity is enabled in the vehicles settings. Monitor Professional Technician System \(PTS\) for additional information.
- [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. For claiming, refer to the Warranty and Policy manual for
- [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 54719](/bulletins/11031262.md), 2026-04-10, Service bulletin: POWER TRAIN. For 20212026 vehicles equipped with the 10R80 transmission, a new Transmission Clutch Circuit Leak Test has been introduced in the Ford Diagnosis and Repair System \(FDRS\). This test utilizes the pressure and vacuum transducer \(PVT\) when available. When referred to a specific clutch \(A\-F\) test by a pinpoint test in Workshop Manual \(WSM\), Section 307\-01 \> Diagnosis and Testing, the Clutch Assembly tests have been updated with a hyperlink to the new Transmission Line Pressure Test \- Pressure Vacuum Transducer \(PVT\) Is Available procedure in WSM, Section 307\-01 \> General Procedures. This procedure provides instructions to perform the FDRS Transmission Clutch Circuit Leak Test when applicable. The new test improves the accuracy of detecting leaks within transmission fluid circuits and replaces the previous air check method. The previous air check procedure has been shown to produce a high rate of false positives, which may lead to unnecessary repairs when no actual leak is present. Accordingly, the air check procedure is not to be used for diagnosing internal transmission hydraulic leaks or as justification
- [SSM 54674](/bulletins/11030791.md), 2026-04-06, Service bulletin: POWER TRAIN. For 2021\-2026 vehicles equipped with the 10R80 transmission, a new Transmission Clutch Circuit Leak Test has been introduced in the Ford Diagnosis and Repair System \(FDRS\). This test utilizes the pressure and vacuum transducer \(PVT\) when available. The Workshop Manual \(WSM\) has been updated under Section 307\-01 \> Diagnosis and Testing to include this procedure. The new test improves the accuracy of detecting leaks within transmission fluid circuits and replaces the previous air check method.
- [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 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.
- [SSM 54392](/bulletins/11025816.md), 2025-12-01, Service bulletin: ENGINE; POWER TRAIN. Some 2021\-2025 F\-150/Expedition/Navigator vehicles equipped with a 3.5L EcoBoost engine may exhibit diagnostic trouble code \(DTC\) P0299 stored in the powertrain control module \(PCM\) and may also exhibit a rattle noise from the turbocharger. This may be due to the wastegate actuator rod being disconnected. Workshop Manual \(WSM\), Section 303\-04 Fuel Charging and Controls \> Turbocharger has been added to address this condition to allow servicing of the turbocharger actuator rod. In addition, the wastegate actuator rod and associated retention springs and clips have been released as lower level components to complete the repair without replacing the entire turbocharger actuator assembly.
- [SSM 54366](/bulletins/11025611.md), 2025-11-19, Service bulletin: POWER TRAIN; ELECTRICAL SYSTEM. Some 2015\-2021 Ford and Lincoln vehicles may exhibit an illuminated MIL with diagnostic trouble codes \(DTCs\) P0011, P0012, P0014, P0015, P0016, P0017, P0018, P0019, P0021, P0022, P0024 and/or P0025. Pinpoint test HK in the Powertrain Control and Emissions Diagnosis \(PC/ED\) or in Section 303\-14 of the Workshop Manual \(WSM\) has been updated to address this concern.
