Official summary
Some 2025 Expedition/Navigator vehicles may exhibit diagnostic trouble codes (DTCs) B150D:55 and/or B150C:55 stored in the audio control module (ACM) when a diagnostic self-test is performed. If no other symptoms, DTCs, or issues are identified, no further action is required. Replacement and/or reprogramming of the ACM will not resolve this condition.
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.
