What is OBD2 or OBD-II?
First, lets understand what ODB2 or ODB-II is and why we need to check its state.
OBD-II is defined as an on-board diagnostic system II that was primarily used to help meet emissions standards. The diagnostics have grown significantly since that time as almost every part of a car is controlled or relies upon a computer to provide it instruction or run diagnostic to keep it operating properly.
Above all it checks your cars sensors to verify that everything is working as it should.
How to check for readiness state.
The easiest way to check if your OBD2 is in the readiness state is to watch this video:
Most importantly in the video it tells you to do the following:
- Put the key in the ignition
- Turn the key two clicks without turning over the motor
- Wait a few seconds and look to see if the check engine light blinks
- If it does you will need to count how many times it does.
- This will tell you if your OBD2 or OBD-II see’s all of the monitors and sensors as ready.
Therefore, we encourage you to watch the video in its entirety to ensure you have followed all of the steps.
