This may be due to incorrect cylinder to DTC mapping within the PCM. This means the DTCs listed may set against the incorrect cylinder. Even though the cylinder to DTC mapping is incorrect in the PCM, the presence of these DTCs means that a real ignition system concern is present that requires diagnosis and repair. Prior to performing a pinpoint test for one of the listed DTCs, it will be necessary to identify the correct cylinder that has the issue. Do this by using the Ford diagnosis and repair system (FDRS) to perform a cylinder power balance test. If the results show two cylinders dropping out, begin diagnosing the ignition system components for the cylinder that is dropping out and not setting an ignition related DTC. Due to the incorrect cylinder to DTC mapping","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10251954-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2024/MC-10251954-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/10251954","components":[{"id":"powertrain","name":"Transmission and driveline","parent":null},{"id":"automatic-transmission","name":"Automatic transmission","parent":"powertrain"},{"id":"transmission-control-module","name":"Transmission control module","parent":"powertrain"}],"codes":["P0352","P0353","P0354","P0355","P0357","P2303","P2304","P2306","P2307","P2309","P2310","P2312","P2313","P2318","P2319","P2322"],"topics":[],"vehicles":[{"make":"FORD","model":"BRONCO","year_from":2021,"year_to":2024,"match":"exact","vehicle_ids":["2021_ford_bronco","2022_ford_bronco","2023_ford_bronco","2024_ford_bronco"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
