| TSB 22-2475 | 2023-01-05. Service bulletin. STEERING. Some 2018-2021 Navigator vehicles may exhibit a grinding, growling or clicking noise or inoperative power steering column during telescoping/raking operation.

| SSM 51131 | 2022-10-19. Service bulletin. UNKNOWN OR OTHER; COMMUNICATION:MANUFACTURER TELEMATICS. Some 2020-2022 Ford and Lincoln vehicles equipped with a telematic control unit (TCU) may exhibit inoperative remote features via Ford Pass/Lincoln Way mobile app, incomplete user authorization, and/or modem electronic serial number (ESN) could not be displayed in the center display screen. To correct this condition prior to programming, remove the TCU fuse for 5-minutes then reinstall. Delete all previous session files for the vehicle. Start a new Ford Diagnosis and Repair System (FDRS) session. Perform a TCU provisioning and Program the TCU to the latest FDRS version level. If the concern is still present, follow normal diagnostics in Workshop Manual (WSM), Section 415-00. Refer to PTS OASIS home page for TCU version identification. For claiming, use causal part 14G229 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual. |
| SSM 51120 | 2022-10-11. Service bulletin. SERVICE BRAKES, HYDRAULIC. Some Ford and Lincoln vehicles may exhibit noise when the brakes are applied. When diagnosing and repairing brake noise conditions, use the Workshop Manual (WSM) and the appropriate pinpoint test in section 206-00. The brake rotors should only be machined if directed by the WSM because one or more of the following conditions are present on the braking surface: scoring, excessive corrosion/rust or pitting, bluing/discoloration and/or heat spots. For additional information, refer to WSM section 206-00. |
| TSB 22-2339 | 2022-09-23. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN. Some 2018-2021 Expedition/Navigator, 2018-2020 F-150/Mustang and 2019-2021 Ranger vehicles equipped with a 10R80 automatic transmission may exhibit an illuminated malfunction indicator lamp (MIL) with diagnostic trouble code (DTC) P163E stored in the powertrain control module (PCM) or transmission control module (TCM) after replacing the main control valve body. This may be due to software incompatibility between the replacement main control valve body solenoid strategy file and the PCM/TCM software. To correct this condition, follow the Service Procedure to enter only the 13-digit solenoid body strategy when downloading transmission strategy. |
| SSM 50982 | 2022-08-15. Service bulletin. EQUIPMENT:ELECTRICAL. Some 2018-2022 Ford/Lincoln vehicles equipped with a wireless charging pad may exhibit one of the following if the customer is using a Magsafe iPhone (iPhone 12 or 13): slow charging, inoperative, notification that the phone has been mispositioned on the charging pad and/or the phone charging icon in the center screen display is not showing. This may be due to a compatibility issue between the customer's phone and the wireless accessory charging module (WACM) that may make it difficult for Ford and Lincoln vehicles to wirelessly charge these specific phones. The phone can still be charged using the USB cable if the vehicle experiences the above symptoms. If the customer is using a Magsafe iPhone such as an iPhone 12 or 13, verify the wireless charging pad works with a Qi certified phone prior to any part replacements. |
| SSM 50975 | 2022-08-02. Service bulletin. ELECTRICAL SYSTEM. Some 2017-2022 Ford/Lincoln customers may experience a notification in the FordPass®/LincolnWay® app indicating Vehicle Has Entered Deep Sleep Mode. This occurs when 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%. A warning may also set if the telematic control unit (TCU) has received an over the air update. The TCU powers down all communication when in this mode and app features are disabled. Manually start the vehicle to wake if from mode. More information is located in the app under: Account > Help > search 'Deep Sleep' in the entry box. If the condition remains, check the BCM 12v SOC. If the SOC does not change after charging the battery or after BMS reset is performed, continue with normal battery and/or BMS sensor diagnostics. |
| SSM 50959 | 2022-07-29. Service bulletin. EQUIPMENT:ELECTRICAL.

This may be due to the SYNC Software. To correct the condition, follow the Service Procedure to update the accessory protocol interface module (APIM) software. |
| TSB 22-2145 | 2022-07-01. Service bulletin. POWER TRAIN. Some 2018-2021 Expedition/Navigator and 2020-2021 Explorer/Aviator vehicles equipped with a 10R80/10R80 MHT or 10R60 may exhibit a momentary transmission neutral-out condition while in drive. Vehicle may also have diagnostic trouble code (DTC) P07E6 and/or P07E4 stored in the powertrain control module (PCM) or transmission control module (TCM) and/or a possible audible noise. This may be due to a leak in the park valve circuit. To correct the condition, follow the Service Procedure to inspect the park system hardware for wear or damage and replace the valve body separator plate with an improved valve body separator plate. |
| SSM 50873 | 2022-06-30. Service bulletin. ELECTRICAL SYSTEM. Some 2017-2022 Ford and Lincoln vehicle owners may experience a condition of missing authorization, command and control, battery charging details or phone-as-a-key setup buttons/selections in their FordPass or LincolnWay App. This condition is due to an error within the FordPass or LincolnWay App and not due to a concern on the vehicle. Verify that the customers FordPass or LincolnWay App is at the latest version. Replacement or reprogramming of the telematics control unit (TCU)/gateway module (GWM)/remote function actuator (RFA) will not resolve this condition. If the condition persists, utilize the FordPass Guides or Lincoln Way Concierge teams. |
| TSB 22-2137 | 2022-06-27. Service bulletin. ELECTRICAL SYSTEM; POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE (TCM/PCM/TECM).

This may be due to high sulfur content in the fuel. To correct the condition, follow the Service Procedure to de-sulfate the catalytic convertors. |
| SSM 50835 | 2022-06-17. Service bulletin. ENGINE AND ENGINE COOLING. Some 2021-2022 F-150 vehicles built on or before 08-Mar-2022 and some 2021-2022 Expedition/Navigator vehicles built on or before 14-Mar-2022 equipped with a 3.5L EcoBoost engine may experience a coolant leak at the thermostat housing. This may be due to an incomplete weld on the thermostat housing which can leak during normal vehicle operation. To correct the condition, replace the thermostat housing using service part number ML3Z-8A586-C. Refer to Workshop Manual (WSM), Section 303-03. For claiming, use causal part 8A586 and applicable labor operations in Section 08 of the Service Labor Time Standards (SLTS) Manual. |

Some 2020-2022 Corsair/Nautilus/Navigator/Aviator, 2021-2022 Mustang Mach-E vehicles equipped with Phone-as-a-Key may exhibit Phone-as-a-Key concerns and have diagnostic trouble code(s) (DTC) U200D:15, U200E:15, U200F:15, B15**:31, B15**:49 and/or B15A5:56 stored in the remote function actuator (RFA) module. If the vehicle is exhibiting other symptoms outside of Phone-as-a-key concerns, address those first. If any of these DTCs are detected during diagnostics, clear the DTCs, reflash 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 B15**:31, B15**:57 and/or B15A5:56 DTC(s) returns in the RFA after a self test, follow normal Workshop Manual (WSM) diagnostics, Section 419-01C. |
| SSM 50841 | 2022-06-17. Service bulletin. ELECTRICAL SYSTEM.
