Can OBD2 Scanner Read Odometer and Reveal Hidden Mileage?
In today’s world, buying a used car can sometimes feel like a gamble. Hidden mileage and potential odometer tampering are concerns for many buyers. Thankfully, technology has advanced, and the OBD2 (On-Board Diagnostics 2) scanner has become an essential tool for car enthusiasts and buyers alike. In this guide, we will dive deep into how OBD2 scanners work, whether they can read odometer values, and how you can use them to reveal hidden mileage.
What is an OBD2 Scanner?
Before we get into the specifics of reading odometer values, it’s essential to understand what an OBD2 scanner is. An OBD2 scanner is a device that connects to a vehicle’s OBD2 port to read diagnostic trouble codes (DTCs) and other relevant data from the car’s Engine Control Unit (ECU).

Step 1: Gather Your Tools
Before you begin, make sure you have the following:
- An OBD2 scanner that supports odometer reading.
- Your vehicle, parked and turned off.
- The vehicle’s manual (optional, but helpful).
Step 2: Locate the OBD2 Port
The OBD2 port is usually located under the dashboard, near the driver’s seat. Look for a connector that resembles a trapezoid shape.
Step 3: Connect the OBD2 Scanner
Plug the OBD2 scanner into the OBD2 port. Ensure the connection is secure.
Step 4: Turn on the Vehicle
Start your vehicle or turn the ignition key to the “On” position without starting the engine. This step powers the scanner.
Step 5: Access OBD2 Scanner Menu
Follow the instructions on your scanner’s display. Navigate to the section where you can read live data or vehicle information. This varies by scanner model.
Step 6: Look for Odometer Data
Search for odometer readings or vehicle mileage in the data menu. If your scanner supports it and the vehicle allows access, you should see the odometer reading displayed.
Step 7: Analyze the Data
If the odometer reading is present, compare it with the displayed mileage on the dashboard. Any discrepancies could indicate tampering.
Practical Tips for Using an OBD2 Scanner
Here are some helpful tips when using an OBD2 scanner:
- Always use an OBD2 scanner compatible with your car’s make and model.
- Make sure the scanner has updated software to access the latest data.
- Be cautious if you find suspicious mileage; consider having a professional mechanic inspect the vehicle.
- Use the scanner regularly to monitor your vehicle’s health and performance.
Troubleshooting Common Issues
Sometimes you may encounter issues while using an OBD2 scanner. Here are some common problems and solutions:
Problem: Scanner Doesn’t Connect
Ensure the scanner is properly plugged into the OBD2 port. Check for blown fuses in your vehicle that may affect the port.
Problem: No Odometer Data
If your scanner cannot retrieve odometer data, it might not be supported by your vehicle’s ECU. Try a different scanner or consult the vehicle’s manual for more details.
Problem: Discrepancy in Mileage
If the mileage on the scanner does not match the dashboard, this could indicate tampering. Validate the mileage with the vehicle’s service history or consult a mechanic.
Conclusion
In conclusion, while not all OBD2 scanners can read odometer values, many advanced models can reveal crucial information about your vehicle’s mileage. By understanding how to use an OBD2 scanner effectively, you can protect yourself from potential scams when buying used cars. Regularly checking your vehicle’s health with an OBD2 scanner is also a great way to ensure optimal performance. Remember, knowledge is power, and being informed can save you money and headaches in the long run!
