Official summary
Some 2021-2024 Bronco/F-150 (non-Lightning) vehicles may exhibit a "Check Charging System" message in the instrument panel cluster (IPC) while the charging system is fully operational and there are no diagnostic trouble codes (DTC) stored related to the charging system. This may be due to the customer using an aftermarket programmer to change body control module (BCM) configuration.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
