Manufacturer summary

Original wording in English

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.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
