Cause This fault is set when there is a voltage demand from the ME, but there was no bus sleep yet. This fault can typically be ignored. It will not set a CEL and doesn't have any influence on the drivability or function of the vehicle. Remedy To clear this fault: - clear the error memory of the vehicle (at least the ETC and ME) - put the vehicle to sleep (lock and wait) and wake up (unlock) - turn ignition ON and read error memory again - DTCs shouldn´t be present in ETC - no CEL is turned ON - vehicle can be started and driven","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11018582-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11018582-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11018582","components":[{"id":"electrical","name":"Electrical system","parent":null},{"id":"engine","name":"Engine","parent":null}],"codes":["P2F1D"],"topics":[],"vehicles":[{"make":"MERCEDES-BENZ","model":"AMG C43","year_from":2023,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG C43 4MATIC","year_from":2023,"year_to":2023,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG CLA45","year_from":2020,"year_to":2024,"match":null,"vehicle_ids":[]},{"make":"MERCEDES-BENZ","model":"AMG GLA45","year_from":2021,"year_to":2023,"match":null,"vehicle_ids":[]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
