What happens here

An AutoZone employee will provide you with a handheld diagnostic scanner. You will need to locate your car's On-Board Diagnostics II (OBD-II) port, which is typically found under the dashboard on the driver's side, often near the foot pedals. Plug the diagnostic scanner's cable into this port. The scanner will then power on and begin to scan your vehicle's computer for diagnostic trouble codes (DTCs).

Goal: Locate your vehicle's OBD-II port, usually near the pedals, and connect the provided handheld diagnostic scanner to it.
