Manufacturer summary

Original wording in English

Some 2021 F-150 vehicles equipped with a 3.5L PowerBoost engine may experience diagnostic trouble code (DTC) U0288 stored in the secondary on-board diagnostic module C (SOBDMC), also referred to as the inverter system controller (ISC). This may be due to various software parameters within the SOBDMC. To correct the condition, follow the Service Procedure to perform a multi-module reprogramming, beginning with the powertrain control module (PCM).

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.
