This may be due to a loose fuse terminal for the low voltage high current fuse (3A). If this condition is present, compare fuse removal effort between the low voltage high current fuse and like fuses in the battery junction box (BCMC). If removal effort for the fuse is low, replace the low voltage high current fuse panel assembly to correct this condition. Refer to Workshop Manual (WSM) Section 414-01 > Removal and Installation > Low Voltage High Current Fuse. For claiming, use causal part 14526 and labor time MT14526SSM with a limit of 0.5 hours.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11029929-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11029929-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11029929","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"powertrain","name":"Transmission and driveline","parent":null}],"codes":["B11DB"],"topics":[],"vehicles":[{"make":"FORD","model":"BRONCO","year_from":2021,"year_to":2023,"match":"exact","vehicle_ids":["2021_ford_bronco","2022_ford_bronco","2023_ford_bronco"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
