# Service bulletin SSM 49412

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.

- Type: Service bulletin

## NHTSA's summary

Some 2019\-2020 Nautilus vehicles may exhibit an inaccurate instrument panel cluster \(IPC\) navigation ETA that conflicts with the navigation ETA in the SYNC display center stack. This may be due to the software in the IPC. To correct the condition, reprogram the IPC using the latest software level of the appropriate Ford diagnostic scan tool. For claiming, use causal part 10849 and applicable labor times from Section 10 of the Service Labor Time Standards \(SLTS\) Manual.

## Other bulletins for the same vehicles and component

- [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 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.
- [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 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.
- [SSM 52076](/bulletins/10245389.md), 2023-11-21, Service bulletin: ELECTRICAL SYSTEM:SOFTWARE; POWER TRAIN:TRANSFER CASE \(4\-WHEEL DRIVE\). Some 2019\-2021 Edge/Nautilus vehicles equipped with all wheel drive \(AWD\) may exhibit a noise from the rear of the vehicle while approaching the vehicle or prior to starting engine. This may be due to the rear drive unit \(RDU\) actuator learning process. Reprogram the software in the AWD module to minimize the noise using the latest software level of the appropriate Ford diagnostic scan tool. If no other concerns or symptoms are present, further diagnosis or repairs are not recommended. For claiming, use causal part 4000 and applicable labor operations in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.
- [TSB 23\-2307](/bulletins/10244707.md), 2023-11-02, Service bulletin: UNKNOWN OR OTHER; EQUIPMENT:ELECTRICAL:NAVIGATIONAL SYSTEM\(GLOBAL POSITIONING SYSTEM\); ELECTRICAL SYSTEM:SOFTWARE; EQUIPMENT:ELECTRICAL:INFOTAINMENT:SOFTWARE. Some 2019\-2020 Edge/F\-150/Fusion/Continental/MKZ/Nautilus, 2019\-2021 Mustang/Ranger/Transit Connect, 2020\-2021 EcoSport/Escape/Expedition/Explorer/F\-Super Duty/Aviator/Corsair/Navigator, 2021 Bronco Sport and 2020\-2022 Explorer/Aviator vehicles with SYNC 3 may experience various SYNC performance related concerns. This may be due to the SYNC Software. To correct the condition, follow the Service Procedure to update the SYNC module \(APIM\) software.
- [TSB 23\-2237](/bulletins/10243471.md), 2023-10-03, Service bulletin: EQUIPMENT. Some 2019\-2022 Nautilus vehicles may exhibit the rubber seal between the spoiler support and the liftgate coming loose. This may be due to poor adhesion between the spoiler and the rubber seal. To correct the condition, follow the Service Procedure to replace spoiler support rubber seal.
- [SSM 51838](/bulletins/10241627.md), 2023-09-04, Service bulletin: ELECTRICAL SYSTEM. In various 2017\-2023 Ford and Lincoln vehicles, customers may receive a message in the FordPass or LincolnWay App stating Feature Unavailable. Since this is a fleet vehicle, it cannot access the \(SYNC Connect\) FordPass or LincolnWay app through the TCU Embedded Modem. If this message appears, the vehicle may be equipped with a fleet telematics module. Replacement of the TCU or TCU related repairs will not prevent this message from appearing. Refer the customer to in app FordPass Guides or LincolnWay Concierge Teams to aid with fleet telematics removal. Open app, select Account \> Help \> CHAT or CALL option.
- [SSM 51823](/bulletins/10240577.md), 2023-08-11, Service bulletin: UNKNOWN OR OTHER; EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL; POWER TRAIN.

This may be due to fluid contamination in the rear drive unit \(RDU\). Drain and refill the RDU, refer to Workshop Manual Section \(WSM\) 205\-02. Drive for 5 miles \(8 km\) in stop and go conditions with right and left turns and re\-evaluate. If the issue is still present, continue with normal WSM diagnostics. For claiming, use base \(4000\) causal part.
