This software flash will allow these permanent fault codes to naturally clear. Customers may experience the following: ● A potential to stall when coming to a stop with an immediate restart. If the engine were to stall while stopping, a message would display in the Instrument Panel Cluster (IPC) informing the driver to shift to park to restart the engine. Other software improvements: ● **High pressure fuel pump actuation during cold start have been changed to shorten the cranking phase.** ● Improvements related to fault codes P0300, P0301, P0302, P0303, P0304, P0305 and P0306 for cold start catalyst heating misfire. **This bulletin involves inspecting and possibly reprogramming the PCM with the latest available software.**","document":{"url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11023070-0001.pdf","alternate_url":"https://static.nhtsa.gov/odi/tsbs/2025/MC-11023070-9999.pdf","confirmed":false},"url":"https://open.wenmarpro.com/bulletins/11023070","components":[{"id":"electrical","name":"Electrical system","parent":null}],"codes":["P00C6","P018B","P0300","P0301","P0302","P0303","P0304","P0305","P0306","P0325","P032A","P0330","P1CEA","P2AF6","U0104","U0405"],"topics":[],"vehicles":[{"make":"RAM","model":"1500","year_from":2025,"year_to":2025,"match":"exact","vehicle_ids":["2025_ram_1500"]}],"as_of":"2026-10-19","note":"A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it.
