Its standardized location and protocol mean that a wide range of OBD2 scanners and apps are compatible with your vehicle. By connecting an OBD2 adapter to this port, you can access data that would otherwise only be available to dealership technicians. This access is invaluable for proactive maintenance and quickly identifying potential problems before they escalate into costly repairs.
