To confirm a vehicle is built with a certain minor feature code, review the build information by double-clicking the vehicle identification number (VIN) in the upper left corner on Professional Technician System (PTS). This may be due to software in the digital signal processing (DSP) module. To correct this condition, reprogram the DSP module to the latest software level using the Ford Diagnosis and Repair System (FDRS) scan tool. For claiming, use causal part 18B849 and labor operations 12651D and 12651D4.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11021977-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11021977-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11021977","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"BRONCO SPORT","year_from":2021,"year_to":2024,"match":"exact","vehicle_ids":["2021_ford_bronco-sport","2022_ford_bronco-sport","2023_ford_bronco-sport","2024_ford_bronco-sport"]},{"make":"FORD","model":"EXPEDITION","year_from":2022,"year_to":2023,"match":"exact","vehicle_ids":["2022_ford_expedition","2023_ford_expedition"]},{"make":"FORD","model":"F-150","year_from":2021,"year_to":2024,"match":"exact","vehicle_ids":["2021_ford_f-150","2022_ford_f-150","2023_ford_f-150","2024_ford_f-150"]},{"make":"FORD","model":"MAVERICK","year_from":2022,"year_to":2024,"match":"exact","vehicle_ids":["2022_ford_maverick","2023_ford_maverick","2024_ford_maverick"]},{"make":"FORD","model":"MUSTANG MACH E","year_from":2021,"year_to":2024,"match":"exact","vehicle_ids":["2021_ford_mustang-mach-e","2022_ford_mustang-mach-e","2023_ford_mustang-mach-e","2024_ford_mustang-mach-e"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
