Hey everyone. Most of us know about the trouble codes that we face in the car. Related to the same, can anyone tell me what is OBD plug in test required for? I am soon gonna go for the emission test. Before going, I just want to be sure about the OBD test as well.

The OBD II is required to to check if the monitor self tests required for a particular car is completed or not. Is it also helpful to check if the check engine light is faulty or functioning properly.
