Today when i tried connecting to my 2002 chevy silverado 5.3l I kept getting an error. I know before in the past i have been able to log on this vehicle but today i kept the error attached. Scan tool was showing i was connected, but it didn't seem like it was. Then when I clicked on the yellow button to start monitoring this is when the error was generated. So what is going on and how to I fix this?
