Official summary
Some 2021 Bronco Badlands and First Edition vehicles built on or before 19-Nov-2021 with a stabilizer bar disconnect system may exhibit an illuminated red and/or amber stabilizer bar disconnect indicator and diagnostic trouble codes (DTC) C103A:74, C1B03:67 and/or C1B07:67 stored in the chassis control module(CHCM). This may be due to the software in the CHCM. To correct the condition, follow the Service Procedure to reprogram the CHCM.
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.
