If the vehicle is in transport mode, disable transport mode and retest. Refer to Workshop Manual (WSM), Section 419-10. If the concern is still present, perform a radio power reset by removing fuse F32 in the body control module (BCM) for 5 minutes. Reinstall the fuse and retest. If the concern is present, disconnect connector C240A from the ACM, reconnect, and retest. If the vehicle still exhibits the concern, refer to WSM, Section 415-00 and proceed with normal diagnostics.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10189586-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10189586-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10189586","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":["C240A","U0184"],"topics":[],"vehicles":[{"make":"FORD","model":"F-250 SD","year_from":2020,"year_to":2021,"match":"base","vehicle_ids":["2020_ford_f-250","2021_ford_f-250"]},{"make":"FORD","model":"F-350 SD","year_from":2020,"year_to":2021,"match":"base","vehicle_ids":["2020_ford_f-350","2021_ford_f-350"]},{"make":"FORD","model":"F-450 SD","year_from":2020,"year_to":2021,"match":"base","vehicle_ids":["2020_ford_f-450","2021_ford_f-450"]},{"make":"FORD","model":"F-550 SD","year_from":2020,"year_to":2021,"match":"base","vehicle_ids":["2020_ford_f-550","2021_ford_f-550"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
