Locating Your Vehicle’s OBD2 Port

Most OBD2 ports are located under the dashboard on the driver’s side, near the steering column. Sometimes, they can be found behind a panel or near the center console. Consult your vehicle’s owner’s manual for the exact location if you’re having trouble finding it.

Tips for Finding the OBD2 Port

Look for a trapezoidal 16-pin connector.
Check around the fuse box area.
The port might have a cover labeled “OBDII” or “Diagnostics.”

Connecting the AutoZone OBD2 Scan Tool

Once you’ve located the port, simply plug the OBD2 scan tool connector into it. Ensure it’s securely connected. The scan tool should power on automatically when the vehicle’s ignition is turned to the “on” position (engine doesn’t need to be running).

Common Connection Issues

Make sure the connector is fully inserted.
Check the scan tool’s power source (some may require batteries).
If the tool doesn’t power on, try starting the engine.

Reading and Interpreting the Codes

Most AutoZone OBD2 scan tools will display diagnostic trouble codes (DTCs). These codes are standardized and indicate specific issues within your vehicle’s systems. Write down the codes displayed on the scanner. You can then look up the meaning of these codes online or consult a repair manual.

Understanding DTCs

DTCs are typically five-character alphanumeric codes.
The first character indicates the system (e.g., “P” for powertrain).
The remaining characters specify the particular problem.

Clearing the Codes

After addressing the issue causing the DTC, you can use the AutoZone OBD2 scan tool to clear the codes. This will turn off the check engine light. However, if the underlying problem isn’t fixed, the check engine light will likely return.
