Check Emissions: The OBD2 system monitors your vehicle’s emissions to ensure compliance with environmental regulations. The port allows you to check if your emission system is functioning correctly.
Clear Codes: After repairing a problem, you can use an OBD2 scanner to clear the trouble codes and reset the check engine light.
