Lighter is constant hot.
The car has to be in ACC mode or Run mode (push and hold the bottom of the starter button down for 10 seconds, like you would to put the car into acc with a single quick button push instead) for the scanner to read.

from further reasearch it's probably going to be a blown fuse causing your issue. or the tool is not making a good connectionbetween the male and female plugs.

Any time you clear a code the C6 has to be driven for a few days or so before a smog test can be done. If that was not true we could clear a code in their parking lot before the test and the light could come right back after the test.

Not connected means just that-----NOT CONNECTED. It has nothing to do with CEL's being present or not.
Read the other posts, the ignition must be on to get a connection between the OBD2 scanner and the car.
