Service bulletin TSB 23-2021

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 2021-2022 Mustang Mach-E vehicles equipped with the rear view camera system only may exhibit the Reverse Brake Assistance Not Available message and diagnostic trouble code (DTC) B1578:78 stored in the image processing module A (IPMA) that cannot be cleared. This may be due to the IPMA software. To correct this condition, follow the Service Procedure to reprogram the IPMA to the latest level.

SSM 497562021-05-03. 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.
