This may be due to various software parameters within the GWM. If this DTC is identified during normal diagnostics, but the vehicle does not exhibit any customer concerns around the GWM operation, this DTC should be disregarded. This DTC does not cause any observable concerns or warning messages and does not affect vehicle performance or durability. Ford is developing a software update which will be delivered to the vehicle via an over-the-air (OTA) GWM update in December 2021 to prevent this DTC from setting erroneously.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10203896-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2021/MC-10203896-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10203896","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"software","name":"Software","parent":"electrical"}],"codes":["U2404"],"topics":[],"vehicles":[{"make":"FORD","model":"F-150","year_from":2021,"year_to":2021,"match":"exact","vehicle_ids":["2021_ford_f-150"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
