Types of Scan Tools for Reading Actual Mileage
There are various types of scan tools on the market, each offering different levels of functionality and complexity. Choosing the right one depends on your specific needs and budget.
Basic OBD2 Scanners
Basic OBD2 scanners are affordable and widely available. They can read and clear basic diagnostic trouble codes (DTCs) and access some live data parameters. However, they may not always provide access to the actual mileage stored in the vehicle’s modules.

Enhanced OBD2 Scanners
Enhanced OBD2 scanners offer more advanced features than basic models. They often include access to ABS, SRS, and transmission data, and some can read the actual mileage from various modules.
Professional Scan Tools
Professional scan tools are the most comprehensive and expensive option. They provide access to all vehicle systems, including the ability to read actual mileage, perform bidirectional controls, and access manufacturer-specific data. For real-time diagnostics, using the best obd2 scan tool with live data is invaluable. It gives you instant insights into the performance of your vehicle.
How to Read Actual Mileage with a Scan Tool
The process of reading actual mileage varies depending on the scan tool and the vehicle’s make and model. However, the general steps are as follows:
- Connect the scan tool to the vehicle’s OBD2 port.
- Turn the ignition on, but do not start the engine.
- Select the appropriate vehicle make and model in the scan tool’s software.
- Navigate to the “Mileage” or “Odometer” section. This may be located under different menus depending on the scan tool.
- The scan tool will then display the actual mileage stored in the vehicle’s modules.
Why is Reading Actual Mileage Important?
Knowing the true mileage of a vehicle is vital for a number of reasons:
- Detecting Odometer Fraud: Odometer rollback is a deceptive practice that can significantly affect a vehicle’s value and safety. A scan tool can help identify discrepancies between the displayed mileage and the actual mileage stored in the vehicle’s computer.
- Accurate Vehicle History: Actual mileage provides a more accurate picture of a vehicle’s usage and wear and tear, enabling informed purchasing decisions.
- Preventative Maintenance: Knowing the true mileage is crucial for scheduling preventative maintenance, such as oil changes, timing belt replacements, and other services based on actual usage.
