Manufacturer summary

Original wording in English

Some 2021 Bronco vehicles built on or before 23-Aug-2021 may experience a charging system fault message displayed in the instrument panel cluster (IPC) and diagnostic trouble codes (DTC) U012D, U0284 and/or U0285 stored in the powertrain control module (PCM). This may be due to water intrusion in the active grille shutter connector. To correct this condition, follow the Service Procedure to inspect for water intrusion in the active grille shutter harness connector and repair as needed.

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.
