Some 2020-2022 F-Super Duty vehicles may exhibit a condition where the engine will not turn off and/or have various electrical symptoms including a dead battery, horn stays on and no crank/no start. The vehicle may also have an illuminated anti-lock braking system (ABS) indicator with diagnostic trouble codes (DTCs) C0020 and U3003 in the ABS module. This may be a result of water/moisture intrusion into the battery junction box (BJB). The BJB is located under the hood of the vehicle. This water/moisture intrusion may be related to the BJB cover not installed completely or broken cover tabs/locking fingers allowing water/moisture into the BJB. To correct the condition, follow the Service Procedure to inspect for water/moisture intrusion into the BJB and replace the BJB and cover if water/moisture intrusion is found.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10226938-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10226938-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10226938","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":["C0020","U3003"],"topics":[],"vehicles":[{"make":"FORD","model":"F-250 SD","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_f-250","2021_ford_f-250","2022_ford_f-250"]},{"make":"FORD","model":"F-350 SD","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_f-350","2021_ford_f-350","2022_ford_f-350"]},{"make":"FORD","model":"F-450 SD","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_f-450","2021_ford_f-450","2022_ford_f-450"]},{"make":"FORD","model":"F-550 SD","year_from":2020,"year_to":2022,"match":"base","vehicle_ids":["2020_ford_f-550","2021_ford_f-550","2022_ford_f-550"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
