Manufacturer summary

Original wording in English

This article supersedes TSB 23-2196 to update the Service Procedure. Some 2021-2022 Bronco vehicles equipped with a 2.7L or 3.0L EcoBoost engine may exhibit various charging system error messages and/or illuminated charging system indicator displayed in the instrument panel cluster (IPC) with diagnostics trouble code (DTC) B11DB set within the body control module (BCM). This may be due to coolant contamination into the battery monitor sensor (BMS) and/or in line connector from a leaking transmission fluid heater coolant control valve. To correct the condition, follow the Service Procedure to clean the BMS connector and replace the transmission fluid heater coolant control valve.

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.
