Most trailer emulator testers will not draw enough current to correctly diagnose these concerns. They may be used to diagnose basic functionality of the iTRM, however, some trailer emulator testers may cause false trailer lamp fault messages to appear. The customer's trailer should be used for diagnosis instead of a trailer emulator tester. Refer to Workshop Manual (WSM), Section 417-01 for normal diagnostics.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10236029-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2023/MC-10236029-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10236029","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"trailer-hitch","name":"Trailer hitch","parent":null}],"codes":[],"topics":[],"vehicles":[{"make":"FORD","model":"EXPEDITION","year_from":2022,"year_to":2023,"match":"exact","vehicle_ids":["2022_ford_expedition","2023_ford_expedition"]},{"make":"FORD","model":"F-150","year_from":2021,"year_to":2023,"match":"exact","vehicle_ids":["2021_ford_f-150","2022_ford_f-150","2023_ford_f-150"]},{"make":"FORD","model":"F-250 SD","year_from":2022,"year_to":2023,"match":"base","vehicle_ids":["2022_ford_f-250","2023_ford_f-250"]},{"make":"FORD","model":"F-350 SD","year_from":2022,"year_to":2023,"match":"base","vehicle_ids":["2022_ford_f-350","2023_ford_f-350"]},{"make":"FORD","model":"F-450 SD","year_from":2022,"year_to":2023,"match":"base","vehicle_ids":["2022_ford_f-450","2023_ford_f-450"]},{"make":"FORD","model":"F-550 SD","year_from":2022,"year_to":2023,"match":"base","vehicle_ids":["2022_ford_f-550","2023_ford_f-550"]},{"make":"FORD","model":"F-600 SD","year_from":2022,"year_to":2022,"match":"base","vehicle_ids":["2022_ford_f-600"]},{"make":"FORD","model":"F-650 SD","year_from":2022,"year_to":2023,"match":"base","vehicle_ids":["2022_ford_f-650","2023_ford_f-650"]},{"make":"FORD","model":"F-750 SD","year_from":2022,"year_to":2023,"match":"base","vehicle_ids":["2022_ford_f-750","2023_ford_f-750"]},{"make":"FORD","model":"MAVERICK","year_from":2022,"year_to":2023,"match":"exact","vehicle_ids":["2022_ford_maverick","2023_ford_maverick"]},{"make":"LINCOLN","model":"NAVIGATOR","year_from":2022,"year_to":2023,"match":"exact","vehicle_ids":["2022_lincoln_navigator","2023_lincoln_navigator"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
