Official summary
This article supersedes TSB 23-2021 to update the service procedure and labor times from M-time to AP-time and add a limit. Some of the vehicles listed in the Model statement above 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.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
