Quick answer

Some 2021 Mustang Mach-E and F-150 vehicles equipped with a 360 degree camera system may experience a Reverse Brake Assist Unavailable message displayed in the instrument panel cluster (IPC) and diagnostic trouble code (DTC) B1578:78 in the image processing module A (IPMA) after an on-demand self test is performed. To clear the Reverse Brake Assist Unavailable message displayed in the IPC, download and run the 360 Degree View Camera Alignment app for the IPMA using the latest version of the Ford Diagnosis and Repair System (FDRS). Once the 360 Degree View Camera Alignment routine is successful and the Reverse Brake Assist Unavailable message is no longer displayed in the IPC, perform a continuous memory self test. If any DTC's persist, continue with Workshop Manual (WSM), Section 419-07 diagnostic procedures.

What this bulletin may mean before buying

Treat this as service research, not a verdict on one car. Before you buy, compare this communication with official recall campaigns, model-level owner complaint patterns, and the exact vehicle’s VIN-decoded specifications. A bulletin can help you ask a seller or dealer sharper questions about software updates, known repairs, warranty extensions and service history.
