I have a 2011 Ford Explorer AWD. Has anyone had or heard of this problem. I Drive my car 200 plus miles and show up to get smog checked and have not disconnected the battery. With the car running the whole time we plug the obd2 in and all monitors are ready and it looks like it going to pass smog!! We turn off the car then turn back on and hook up the machine and run the tests and it fails saying incomplete monitors. I then drive the car another 80 plus miles plug in again while the car running and everything is complete but as soon as I turn the ignition off it resets and I get incomplete monitors again. Can anyone Help or have any ideas
