This DTC sets due to an internal BCM timing issue during the self-test process. This specific code has no customer impact and does not cause any drivability concerns or warning messages. Clearing DTC U211B:43:48, reprogramming the BCM, or replacing the BCM is unlikely to prevent this DTC from setting. This DTC does not trigger a condition covered under warranty. Note: This guidance only applies to U211B with the specific failure byte 43 in status 48. Any other trusted real-time operation network (TRON) DTCs or different failure bytes associated with U211B are still applicable and technicians must follow Workshop Manual (WSM) normal diagnostics for those DTCs.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11037569-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11037569-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11037569","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":["U211B"],"topics":[],"vehicles":[{"make":"FORD","model":"EXPEDITION","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_ford_expedition","2026_ford_expedition"]},{"make":"FORD","model":"EXPLORER","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_ford_explorer"]},{"make":"FORD","model":"F-150","year_from":2024,"year_to":2026,"match":"exact","vehicle_ids":["2024_ford_f-150","2025_ford_f-150","2026_ford_f-150"]},{"make":"FORD","model":"F-250 SD","year_from":2026,"year_to":2026,"match":"base","vehicle_ids":["2026_ford_f-250"]},{"make":"FORD","model":"F-350 SD","year_from":2026,"year_to":2026,"match":"base","vehicle_ids":["2026_ford_f-350"]},{"make":"FORD","model":"F-450 SD","year_from":2026,"year_to":2026,"match":"base","vehicle_ids":["2026_ford_f-450"]},{"make":"FORD","model":"F-550 SD","year_from":2026,"year_to":2026,"match":"base","vehicle_ids":["2026_ford_f-550"]},{"make":"LINCOLN","model":"AVIATOR","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_lincoln_aviator"]},{"make":"LINCOLN","model":"NAVIGATOR","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_lincoln_navigator","2026_lincoln_navigator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
