How do you reset engine control after overheating?

To reset the engine control after overheating, first ensure the engine has cooled down completely to avoid burns. Disconnect the battery for about 15 minutes to clear any stored trouble codes in the engine control unit (ECU). Reconnect the battery, then start the engine and allow it to idle, monitoring for any warning lights or issues. If the overheating persists, it’s crucial to diagnose and address the underlying cause before resetting the ECU again.
