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 steps to inspect for water/moisture intrusion into the BJB and replace the BJB if water/moisture intrusion is found.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10180333-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2020/MC-10180333-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10180333","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null},{"id":"equipment","name":"Equipment and accessories","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"F-250 SD","year_from":2020,"year_to":2020,"match":"base","vehicle_ids":["2020_ford_f-250"]},{"make":"FORD","model":"F-350 SD","year_from":2020,"year_to":2020,"match":"base","vehicle_ids":["2020_ford_f-350"]},{"make":"FORD","model":"F-450 SD","year_from":2020,"year_to":2020,"match":"base","vehicle_ids":["2020_ford_f-450"]},{"make":"FORD","model":"F-550 SD","year_from":2020,"year_to":2020,"match":"base","vehicle_ids":["2020_ford_f-550"]},{"make":"FORD","model":"F-650 SD","year_from":2020,"year_to":2020,"match":"base","vehicle_ids":["2020_ford_f-650"]},{"make":"FORD","model":"F-750 SD","year_from":2020,"year_to":2020,"match":"base","vehicle_ids":["2020_ford_f-750"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
