How do you do a hard set reset for your ecm?

Hey, my name is Dusty and I'm one of the auto experts with RepairPal's Car Genius team here to help! If you don't have access to a diagnostic scan tool to clear the codes, you can try disconnecting the battery for approximately 10 minutes or so. Some modern vehicles aren't affected by this and the ECM will require intervention to clear any stored codes. After reconnecting the battery, start the vehicle and allow it to idle for a few minutes, preferably until the vehicle reaches normal operating temperature, then drive the car for a bit to see if the check engine light persists. If it does, there might be an underlying issue beyond just the throttle body, it could be software-related, or something wrong with the electrical circuit causing the persistent state. It could be beneficial to have a professional diagnose and remedy the problem to ensure it's properly resolved.
