  • OK means system has been tested and has passed the test
  • INC means the system has not been tested yet. 

To pass a state emission test you need all OK (except the N/A). Some states may allow you to pass with one incomplete. This screen can be used to show if the check engine light was cleared or erased. If several of these items show as INC it means check engine light was recently reset.
