14. Troubleshooting the Fix Finder Scan Tool

Even with its user-friendly design, some issues can arise while using the Fix Finder scan tool. Here’s how to handle them:

14.1. LCD Screen is Blank

• Problem: No power to the Data Link Connector (DLC).
• Solution: Check your vehicle’s fuse panel and replace any blown fuses. If the issue persists, consult your vehicle’s repair manual to locate the proper computer (PCM) fuse or circuit and perform necessary repairs before proceeding.

14.2. No Codes Recorded

• Problem: No Diagnostic Trouble Codes (DTCs) recorded during the scan.
• Solution: The issue might be manufacturer-specific and require a dealership visit. Run a complete drive cycle to ensure all monitors are active and self-testing, then try retrieving the code again.

14.3. Connector Doesn’t Fit

• Problem: The connector doesn’t fit into the OBD2 port.
• Solution: Your vehicle may be older than the standardized OBD-II protocol. A different tester may be required.

15. Interpreting the Scan Tool Indicators

The Fix Finder scan tool uses LED lights to provide a quick overview of your engine system conditions:

15.1. Green LED (checkmark)

• Meaning: All engine systems are “OK” and running normally. All monitors are active, performing diagnostic testing, and no trouble codes are present.

15.2. Yellow LED (question mark)

• Meaning: Some monitors have not finished their diagnostic self-testing, or there is a ‘pending’ DTC in the system.
• Solution: Complete a full drive cycle to allow all monitors to run, then try retrieving the code again.

15.3. Red LED (X)

• Meaning: A problem exists with one or more of the vehicle’s systems, or one or more DTCs are present. The Check Engine Light on the instrument panel will likely be on.

Remember to return the scan tool to an AutoZone employee when finished, as these tools are specifically designed to work with Z-Net terminals at AutoZone. The AutoZoner will download the data and provide advice on potential problems. Issues can range from a loose gas cap to a faulty oxygen sensor, or more complex concerns requiring additional testing.
