This may be due to the software in the audio control module (ACM). To determine if it is a software concern, disconnect the vehicle's 12-volt battery cables for 10 minutes and reconnect. If the concern is still present, continue with normal diagnostics in Workshop Manual (WSM), Section 415-00 Information and Entertainment System > General Information > Diagnosis and Testing and repair as necessary outside of this article. If the no audio/sound concern is resolved, reprogram the ACM using the latest software level of the Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 18C869 and labor operations 10654C, 12651D and 12651D4.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11035106-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11035106-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11035106","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"BRONCO","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_ford_bronco","2026_ford_bronco"]},{"make":"FORD","model":"BRONCO SPORT","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_ford_bronco-sport","2026_ford_bronco-sport"]},{"make":"FORD","model":"F-150","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_ford_f-150","2026_ford_f-150"]},{"make":"FORD","model":"F-250 SD","year_from":2025,"year_to":2026,"match":"base","vehicle_ids":["2025_ford_f-250","2026_ford_f-250"]},{"make":"FORD","model":"F-350 SD","year_from":2025,"year_to":2026,"match":"base","vehicle_ids":["2025_ford_f-350","2026_ford_f-350"]},{"make":"FORD","model":"F-450 SD","year_from":2025,"year_to":2026,"match":"base","vehicle_ids":["2025_ford_f-450","2026_ford_f-450"]},{"make":"FORD","model":"F-550 SD","year_from":2025,"year_to":2026,"match":"base","vehicle_ids":["2025_ford_f-550","2026_ford_f-550"]},{"make":"FORD","model":"MAVERICK","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_ford_maverick","2026_ford_maverick"]},{"make":"FORD","model":"MUSTANG","year_from":2026,"year_to":2026,"match":"exact","vehicle_ids":["2026_ford_mustang"]},{"make":"FORD","model":"MUSTANG MACH E","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_ford_mustang-mach-e","2026_ford_mustang-mach-e"]},{"make":"FORD","model":"RANGER","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_ford_ranger","2026_ford_ranger"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
