Service bulletin SSM 52465

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 2023-2024 Mustang Mach-E/Corsair and 2024 Mustang vehicles may exhibit an audio control module (ACM) programming failure with a message displayed in the Ford Diagnosis and Repair System (FDRS) scan tool indicating Procedure Unsuccessful-Flash Software Failed To Flash. This may be due to the ACM programming routine. To correct this condition, download and click the refresh icon located next to the run icon to update the ACM - Programmable Module Installation (PMI) app. For claiming, use causal part 18C869 and applicable labor operations in Section 11 of the Service Labor Time Standards (SLTS) Manual.
