A Complete Test means that your OBD2 scanner has gathered and checked enough data during the vehicle self-diagnostic test that determines all inspection results to be perfectly working and ready for an emission test.

Not Applicable tests are inspection monitors that are not tested or necessary when you perform a drive cycle. Not all test monitors apply to all vehicle models and manufacturing dates. The best example is when you perform a 'Variable Timing' test, it only applies to vehicles manufactured from 1996. For this reason, vehicle models in the early 90s don't require any variable timing states.
Note: Disregard and ignore an inspection monitor under a 'Not Applicable' result because the vehicle system does not use it.
Not Complete Tests are the inspection monitors that fall under the following criteria:
Note: This case applies if your check engine light is on or you have pending and confirmed trouble codes.
Note: An OBD2 Scanner readiness check won't be able to determine if your monitor test results are either incomplete because it needs to complete a drive cycle or incomplete because it fails. If you have an incomplete result and don't have any pending or confirmed engine trouble codes, you can refer to the Drive Cycle article to learn how to complete your self-test before your vehicle's smog test.
