How to Check if Your Car Will Pass State Emission Readiness Test using an OBD2 Scanner
Emission readiness checks are important for ensuring your vehicle will pass the state emission test, also known as the readiness test or I/M test. Instead of guessing if your car will pass the emission test, use a YOUCANIC scanner to stay on top of it and catch potential problems early.

Will my car pass the state emission test?
In order for your car to pass the emission test the MIL should be OFF as in the following picture. If the MIL status is ON then your car will not pass emission test, it will fail.
In addition, for the car to pass the state emission test, the MONITORS INC should be 0. So both the MIL STATUS should be OFF and MONITORS INC should be 0.
If the monitor’s INC is a number higher than 0, then you need to drive the vehicle for a couple of days so that the monitors can complete the switch from INC to OK.
