Official summary
Some 2020-2021 Explorer/Aviator and 2021 Bronco vehicles may exhibit an illuminated airbag warning indicator with diagnostic trouble code (DTC) B1404:13 and/or B1407:13. This may be due to contamination and relative movement in the connection between the wiring harness and the side airbag. To correct the condition, follow the Service Procedure steps to replace the affected connector with a service pigtail and the affected side airbag.

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.
