Carolco: On cars built after 2004 that have a Gateway module (this is the diagnostic master module) that uses UDS protocol, a scan needs the ignition to be switched-on, but doesn't require the engine to be running. So, the basic requirement for UDS/ODX based modules when a scan is being performed is the existence of what's called a Terminal 15 voltage- which appears when the key is inserted and the lock is turned to the first click-position
