Service bulletin 23B49

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.

SSM 51338	2023-03-04. Service bulletin. Some 2020-2023 Aviator vehicles may exhibit a concern where the center display screen will not shift to night mode or has lines on the center display screen with multi color or rainbow hue. This may be due to accessory protocol interface module (APIM) software. To correct the condition, run the APIM-SYNC Module (APIM) Standard Programming application using the latest software level of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 14G371 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 51248	2023-01-05. Service bulletin. Some 2015-2020 Edge, 2016-2018 MKX, 2019-2020 Nautilus, 2018-2021 Expedition/Navigator, and 2020-2021 Escape/Corsair/Explorer/Aviator vehicles may exhibit an inoperative power liftgate. This may be due to the rear gate trunk module (RGTM) software. To correct the condition, reprogram the RGTM using the latest software level of the appropriate Ford diagnostic scan tool. For claiming, use causal part 14B291 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
SSM 51169	2022-11-29. Service bulletin. Some 2020-2022 Aviator/Explorer Hybrid vehicles may experience a concern where the EV power flow does not display in the center display screen. This may be due to accessory protocol interface module (APIM) software. To correct the condition, run the APIM-SYNC Module (APIM) Standard Programming application using the latest software level of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 14G371 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
TSB 22-2254	2022-07-01. Service bulletin. 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 accessory protocol interface module (APIM) software.
SSM 49756	2021-05-03. Service bulletin. Some 2018-2021 vehicles supported by FDRS may not list a software update for a module under the SW Updates tab although an SSM or TSB is published for a software update. This may be due to the module already being at the latest software level. A later software level may have been programmed at the assembly plant, during a previous dealer visit or by an over the air (OTA) update for vehicles that have automatic updates enabled in the SYNC system settings. To review a vehicle's OTA update history, visit the Connected Vehicle > OTA Dashboard tab in OASIS. Information about the OTA Dashboard can be found on FMCDealer.com when performing a search on OTA History Job Aid.

Some 2020-2021 Aviator vehicles equipped with a 360 degree view camera system and built on or before 07-Dec-2020 may exhibit an intermittent blank or blue screen when placed into reverse but return to normal when placed into drive. This condition may be more noticeable during cool or colder temperatures. To correct the condition, reprogram the image processing module B (IPMB) using the latest software version of the appropriate Ford scan tool. For claiming, use causal part 19H405 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.
