How AutoZone’s Free OBD2 Scan Works
AutoZone offers a complimentary OBD2 scanning service through their Fix Finder tool. Here’s a breakdown of how it works:
Borrowing the OBD2 Scanner
- Visit your local AutoZone: Locate your nearest AutoZone store.
- Request the Fix Finder tool: Ask an AutoZone employee for the OBD2 scan tool, also known as the Fix Finder.
- Vehicle Preparation: Ensure your car is turned off, in park, and the parking brake is engaged.
Connecting and Using the Scanner
- Locate the DLC: Find the Data Link Connector (DLC) port under your dashboard, usually on the driver’s side.
- Connect the Scanner: Plug the Fix Finder tool into the DLC. It’s keyed to only fit one way.
- Turn on the Ignition: Turn the ignition key to the “on” position without starting the engine.
- Read the Codes: The Fix Finder will automatically link with your car’s computer and read the diagnostic trouble codes (DTCs). The process typically takes a few seconds. The LCD screen on the tool will display “read” and then “done.”
- Disconnect and Turn Off: Once the scan is complete, disconnect the tool and turn off the ignition.
Getting Your Diagnostic Report
- Provide Vehicle Information: Give the AutoZone employee your vehicle’s year, make, model, and engine size.
- Report Retrieval: The employee will download the data from the Fix Finder using a Z-Net terminal.
- Review Results: The AutoZoner will explain the DTCs and offer potential solutions. You’ll also receive a printed copy of the report.
Understanding the Fix Finder Indicators
The Fix Finder has LED lights to provide a quick visual indication of your engine’s status:
- Green (checkmark): All systems are OK.
- Yellow (question mark): Some diagnostic tests are incomplete or a pending code exists. A full drive cycle may be needed.
- Red (X): Indicates a problem with one or more vehicle systems and that DTCs are present. Your check engine light will likely be illuminated.
Troubleshooting Potential Issues
- Blank LCD Screen: Check your vehicle’s fuse box for a blown fuse related to the DLC. Consult your repair manual if replacing the fuse doesn’t solve the issue.
- No Codes Found: The problem might be manufacturer-specific, requiring a dealership visit.
- Connector Doesn’t Fit: Your vehicle might be older than the OBD-II standard, requiring a different scan tool.
Conclusion
AutoZone does provide free OBD2 scans using their Fix Finder tool. This service can help you understand why your check engine light is on and guide you towards the necessary repairs. While AutoZone provides the code reading and potential solutions, further diagnostics or repairs may be needed by a qualified mechanic. Remember to ask an AutoZone employee for assistance if you have any questions.
