| SSM 52476 | 2024-05-03. Service bulletin. EQUIPMENT. All accessory stick-on keyless entry keypads come with a wallet card containing the master code. If the accessory keypad was factory installed, this card will be placed in the glove box and should be handed to the vehicles owner during initial delivery. Unlike the integrated (wired) factory keypad, the accessory keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool. If the wallet card for an accessory keypad is lost, follow these steps to recover the code. Dealer Key Code access is granted through the Dealer Program Enrollment System (DPES); dealership management can authorize users. The authorized user must go to FMCDealer.com > Parts and Service > Parts Product Line Information > Keys/Entry Devices > Aftermarket Keyless Entry Keypad Code Access. Follow the instructions on the screen to obtain the master code for the accessory keypad. |

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. |
| SSM 51937 | 2023-10-05. Service bulletin. EQUIPMENT. Some vehicles equipped with power folding mirrors may exhibit power folding mirrors that are inoperative or exhibit a clicking sound. This may be due to the mirrors being manually folded in, during transportation, going through a car wash, bumped in a parking lot, or found during pre-delivery inspection (PDI). Prior to the replacement of any components, attempt to synchronize the mirrors by following the Power Mirrors Synchronization procedure. Refer to Workshop Manual (WSM) Section 501-09 Rear View Mirrors - General Procedures - Power Mirrors Synchronization. |
| SAN-Vol1 I1 | 2023-08-16. Service bulletin. EQUIPMENT:OTHER:OWNERS/SERVICE/OTHER MANUAL. The Service Awareness Newsletter is an informal communication that contains information that may not be presently available in a TSB, SSM, GSB, or other electronic communication. This article includes information on warranty, technical service tips and other service information. |
| SSM 51829 | 2023-08-14. Service bulletin. EQUIPMENT; VISIBILITY:REARVIEW MIRRORS/DEVICES. Some F-Super Duty and F-150 vehicles equipped with trailer tow mirror may exhibit various exterior rear view mirror functional concerns that require replacement after diagnosis. To properly determine if the defect is warrantable, cleaning and close inspection of the affected mirror may be required. To aid in proper warranty determination, the Rear-View Mirror Analysis general service bulletin (GSB) has been updated with a detailed cleaning procedure that should be followed prior to any inspection. New labor operations (17682ZZ or 17682ZZT) have been created that covers the cleaning and inspection process and may be used even if condition of failure is non-warrantable. Ford has inspected numerous returned parts and determined many cases are caused by damage which is unwarrantable and may be subject to chargeback. Refer to the latest version of the GSB on OASIS. |
| SSM 51648 | 2023-05-31. Service bulletin. POWER TRAIN; EQUIPMENT. Some 2020-2022 F-Super Duty vehicles equipped with a 6.7L engine may experience a lack of power due to snow packing of the engine air cleaner when operating in extremely snowy conditions. This may also be due to ice forming in the air intake while operating in temperatures below -22°F (-30°C). Diagnostic trouble code (DTC) P1548 may be present in the powertrain control module (PCM). To supplement heavy snow environment pre-filter service kit (service part LC3Z-9K635-AA), a front grill cover (service part NC3Z-19A413-A) is now available for service but is not a warrantable item. It is recommended that the front grill cover be removed at temperatures greater than 10°F (-12°C) and reinstall in subsequent winter seasons in order to maintain optimal vehicle performance. |
| TSB 23-2115 | 2023-05-04. Service bulletin. EQUIPMENT. Some 2015-2020 F-150 and 2017-2022 F-Super Duty vehicles may exhibit a lack of heat or cooling from the cabin vents when the climate control settings are adjusted between hot and cold. This may be due to a stuck/binding temperature door within the climate control housing or binding/inoperative temperature door actuator. Diagnostic trouble code (DTC) B1081:07 may be present in the front controls interface module (FCIM) or heating ventilation and air conditioning (HVAC) module. To correct the condition, follow the Service Procedure to remove the climate control housing and replace the temperature door cam(s), lubricate the temperature blend door bearing surface, and apply flock tape to actuator to seal out debris. |
| SSM 51449 | 2023-04-05. Service bulletin. EQUIPMENT:ELECTRICAL. 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 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. |

| TSB 22-2443 | 2022-12-02. Service bulletin. UNKNOWN OR OTHER; EQUIPMENT:ELECTRICAL; ELECTRICAL SYSTEM. This article supersedes TSB 22-2313 to update the Parts List, Service Procedure, and vehicle production fix dates. Some 2020-2022 F-Super Duty vehicles may exhibit a condition where the engine will not turn off and/or have various electrical symptoms including a dead battery, horn stays on and no crank/no start. The vehicle may also have an illuminated anti-lock braking system (ABS) indicator with diagnostic trouble codes (DTCs) C0020 and U3003 in the ABS module. This may be a result of water/moisture intrusion into the battery junction box (BJB). The BJB is located under the hood of the vehicle. This water/moisture intrusion may be related to the BJB cover not installed completely or broken cover tabs/locking fingers allowing water/moisture into the BJB. To correct the condition, follow the Service Procedure to inspect for water/moisture intrusion into the BJB and replace the BJB and cover if water/moisture intrusion is found. |
| SSM 50982 | 2022-08-15. Service bulletin. EQUIPMENT:ELECTRICAL.

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. |

This may be due to a loose fuel filler cap. The fuel filler cap design has changed, requiring multiple turns to seal properly. Advise the customer to turn the fuel filler cap clockwise until there is at least one audible click to seal properly. For further diagnostics, refer to Workshop Manual (WSM), Section 303-13 - pinpoint test HX. |

| SSM 50636 | 2022-03-29. Service bulletin. POWER TRAIN:AUTOMATIC TRANSMISSION:CONTROL MODULE:SOFTWARE; ENGINE AND ENGINE COOLING; EQUIPMENT. 2011-2022 F-Super Duty and 2016-2023 F-650/F-750 vehicles equipped with a 6.7L engine may exhibit an elevated idle condition. During prolonged idle time, vehicles may experience this elevated idle to reduce unburned hydrocarbons from the SCR. The powertrain control module estimates hydrocarbon levels in the SCR and may increase idle speed to remove them. Idle speed will be increased to 1000 RPM for ambient temperatures near 26°C (80°F) and may increase to 1200 RPM at -40 °C (-40°F). Vehicles may exhibit exhaust smoke and diesel exhaust fluid smell during elevated idle condition. Exhaust smoke and smell condition will not affect reliability or durability of the engine. Power take-off (PTO) use and idle set point control will disable elevated speed. It is required that the operator monitor the vehicle and adhere to any Exhaust Filter warning messages. |
