The following diagnostic trouble codes (DTCs) may also be stored in the powertrain control module (PCM): U012D, U042E, U0284, U0285, and/or U0645. This may be due to local interconnect network (LIN) circuit VE181 (WH-GN), near connector C102A, being shorted to ground near the left engine mount bracket. If this wire is found to be shorted, repair as need per Wiring Diagram, Cell 005 and secure the harness assembly away from the engine mount bracket to prevent a recurrence.","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10211723-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2022/MC-10211723-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10211723","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":["C102A","U012D","U0284","U0285","U042E","U0645"],"topics":[],"vehicles":[{"make":"FORD","model":"F-150","year_from":2021,"year_to":2022,"match":"exact","vehicle_ids":["2021_ford_f-150","2022_ford_f-150"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
