NHTSA Service Bulletin 11030806: 2024-2026 Ford Bronco
Official manufacturer communication context for 2024-2026 Ford Bronco, with affected products, buyer checks and links into Carchieve recall, problem and VIN research.
Reviewed June 2026 from NHTSA manufacturer communication and service bulletin records. Carchieve is independent and not affiliated with any vehicle manufacturer or government agency.
Some 2024-2026 Bronco vehicles that have the dealer installed option (DIO)/accessory trailer tow kit installed may exhibit a condition where the trailer module (TRM) is not detected, or a "Procedure Unsuccessful" message is displayed after running a configuration application using the Ford Diagnosis and Repair System (FDRS) scan tool. This may be due to any of the following issues:<br /><br /> -The FDRS scan tool version is not at the latest software level. To correct this condition, run the "Towbar Configuration" application using the latest software version of the FDRS scan tool.<br /><br /> -The "TRM - Trailer Module (TRM) Configuration" application being run instead of the "Towbar Configuration" application. Accessory TRMs are preprogrammed and only the "Towbar Configuration" application should be run to configure the TRM properly for trailer tow capabilities. Too many attempts to program the TRM using the "TRM - Trailer Module (TRM) Configuration" application may result in a faulted TRM.
