# Service bulletin SSM 49500

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.

## NHTSA's summary

Some 2020 Navigators vehicles may have a symptom of the interior and/or ambient temperature not showing at the top of the SYNC screen after updating the SYNC software. To resolve this condition, reflash the SYNC module with the latest software using the appropriate Ford diagnostic scan tool and Workshop Manual \(WSM\), Section 415 \> General Procedures \> SYNC Module Programming. For claiming, use causal part 14G371 and applicable labor operations in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.

## Other bulletins for the same vehicles and component

- [SSM 51248](/bulletins/10228866.md), 2023-01-05, Service bulletin: BACK OVER PREVENTION:SOFTWARE. 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.
- [TSB 22\-2254](/bulletins/10214878.md), 2022-07-01, Service bulletin: BACK OVER PREVENTION: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 accessory protocol interface module \(APIM\) software.
- [SSM 49756](/bulletins/10191521.md), 2021-05-03, Service bulletin: BACK OVER PREVENTION:SOFTWARE. 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.
