This may be due to the software in the accessory protocol interface module (APIM). Replacement or reprogramming of the APIM will not resolve this condition. Inform customers that engineering is currently working on a software solution for this condition and will be released via a software update delivered over-the-air (OTA) expected by April 2026. The software will update automatically if vehicle connectivity is enabled in the vehicle settings. Schedule a service visit for customers who have disabled vehicle connectivity or who report that they did not receive the update by May 2026. Monitor Professional Technician System (PTS) for additional information.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11027823-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2026/MC-11027823-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11027823","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPEDITION","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_ford_expedition"]},{"make":"FORD","model":"EXPLORER","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_ford_explorer","2026_ford_explorer"]},{"make":"LINCOLN","model":"AVIATOR","year_from":2025,"year_to":2026,"match":"exact","vehicle_ids":["2025_lincoln_aviator","2026_lincoln_aviator"]},{"make":"LINCOLN","model":"NAUTILUS","year_from":2024,"year_to":2026,"match":"exact","vehicle_ids":["2024_lincoln_nautilus","2025_lincoln_nautilus","2026_lincoln_nautilus"]},{"make":"LINCOLN","model":"NAVIGATOR","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_lincoln_navigator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
