Official summary
Some 2021-2022 Bronco vehicles may exhibit an illuminated powertrain malfunction (wrench) indicator with diagnostic trouble codes (DTCs) stored in the all-wheel drive (AWD) module. The setting of these DTCs result in an inoperative 4WD system that may be intermittent. These DTCs may be setting due to a low battery state of charge. To correct the condition, follow the Service Procedure to verify the battery condition and reprogram the AWD module.

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.
