Manufacturer summary

Original wording in English

Some 2021-2022 F-150 vehicles equipped with a 3.5L PowerBoost engine may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble code (DTC) P2C44:00 stored in the powertrain control module (PCM). This may be due to the software in the PCM and the auxiliary battery isolator. To correct the condition, follow the Service Procedure to reprogram the PCM and replace the auxiliary battery isolator.

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.
