On-Board Diagnostics 2nd Generation (OBD2) tools have become increasingly common in the automotive world. Initially designed for vehicle diagnostics, they’re now used for a variety of purposes, from reading engine codes to tracking driving behavior. This versatility leads many to wonder about their capabilities, specifically, “can you Change Odometer Reading With Obd2?” For those in industries reliant on accurate mileage data, like auto insurance, vehicle maintenance, and road usage charging, understanding the true function and limitations of OBD2 in relation to odometer readings is crucial. While OBD2 tools offer valuable insights into vehicle health and performance, are they really the solution for obtaining or even altering a car’s mileage? Let’s delve into the realities and explore why, for businesses needing reliable mileage verification, alternative solutions are not just preferable, but essential.
The Misconception of OBD2 for Odometer Changes
It’s a common misconception that OBD2 devices can directly access and modify a vehicle’s odometer reading. This idea often stems from the fact that OBD2 ports provide access to a wealth of vehicle data. However, the reality is more nuanced. While OBD2 scanners can read certain data related to mileage, they typically don’t provide the actual, legally recognized odometer reading displayed on your dashboard.

The data that OBD2 devices usually access regarding mileage is often an estimated mileage calculated from various sensors like wheel speed and GPS data if available. This estimation is primarily for trip tracking and performance analysis, not for official odometer verification or modification. Attempting to “change odometer reading with OBD2” in the sense of legally altering the vehicle’s recorded mileage is generally not possible through standard OBD2 functions and would be illegal and unethical in most jurisdictions.
Inaccurate Mileage Data: Estimation vs. Reality
One of the significant drawbacks of relying on OBD2 devices for mileage data is their inherent inaccuracy in providing the true odometer reading. Instead of directly accessing the car’s official odometer, OBD2 trackers often infer mileage based on factors like GPS location and speed. This estimation, while useful for some applications, is prone to errors.

Imagine a scenario where a trip’s starting or ending point is incorrectly detected. Even minor discrepancies in these estimations can accumulate and lead to significant inaccuracies over time. For businesses that depend on precise mileage data for critical functions like insurance risk assessments or accurate service recommendations, these inaccuracies can have tangible negative consequences. Furthermore, the comprehensiveness of data is also questionable. Are businesses truly getting a complete and reliable picture of mileage across their entire customer base when relying on potentially flawed OBD2 estimations?
Inconvenience and Unintentional Failure
Beyond accuracy, OBD2 dongles present practical challenges in terms of user experience and reliability. For everyday drivers, the process of using an OBD2 device involves a series of steps that can be inconvenient. They need to order the device, wait for it to be delivered, and then figure out how to properly install it in their vehicle.

Even after installation, there’s no guarantee of seamless operation. Some vehicles may react negatively to OBD2 devices, causing issues like false warning lights or even battery drain. The physical nature of OBD2 dongles also makes them susceptible to unintentional failure. A loose connection, a bump, or accidental removal can disrupt data collection without the driver even realizing it. This unreliability can create significant problems, particularly when consistent and uninterrupted mileage tracking is essential.
Intentional Tampering and Mileage Fraud Risks
While the question is “can you change odometer reading with OBD2?”, the more relevant concern for businesses is the potential for mileage manipulation and fraud associated with these devices. Even if drivers aren’t directly altering the main odometer with OBD2, the ease of unplugging or disabling these dongles presents a loophole for misreporting mileage.

A driver intending to underreport their mileage, for instance, to lower insurance premiums or avoid charges based on usage, could simply disconnect the OBD2 device during periods of heavy driving. This intentional tampering is difficult to detect and poses a significant risk, especially for industries like auto insurance where mileage fraud is already a substantial problem. The financial implications of mileage fraud are considerable, costing auto insurers billions annually. This issue extends beyond insurance, impacting service providers who rely on accurate mileage for maintenance schedules and billing.
Privacy and Cost Concerns Add to the Drawbacks
In today’s data-conscious world, privacy concerns are paramount. OBD2 dongles, constantly plugged into a vehicle and collecting data, can raise red flags for drivers concerned about their personal information. Many users are wary of the lack of transparency surrounding what data is being collected, how it’s being used, and who has access to it. This lack of clear data consent and control can erode trust and hinder adoption, especially for consumer-facing applications.
Furthermore, the cost associated with OBD2 dongles can be surprisingly high, especially when scaled across a large customer base. Businesses bear the expenses of purchasing the hardware, shipping it to customers, and handling replacements for lost or damaged devices. Ongoing subscription fees for data services further add to the financial burden. These costs, coupled with the logistical complexities of distribution and maintenance, can make OBD2 dongles a less economically viable solution compared to software-based alternatives.
Connected Car APIs: A Superior Approach to Mileage Verification
Recognizing the limitations and drawbacks of OBD2 devices, a more efficient and reliable solution for mileage verification lies in leveraging connected car APIs like Smartcar. These APIs offer a software-centric approach that directly addresses the shortcomings of hardware-based OBD2 trackers.
Accuracy, Ease of Use, and Reliability Redefined
Connected car APIs provide direct access to a vehicle’s actual odometer reading, sourced directly from the car’s computer. This eliminates the estimations and inaccuracies inherent in OBD2 mileage calculations. The onboarding process is significantly simplified, often requiring just a few clicks for users to grant data access through their car’s existing account. There’s no hardware to install, no risk of loose connections, and no potential for battery drain.

The reliability of data is also enhanced. APIs retrieve odometer data automatically and consistently, eliminating the risk of tampering by disconnecting a device. This ensures a continuous stream of accurate data, crucial for reliable service delivery and fraud prevention.
Enhanced Privacy and Cost-Efficiency
Connected car APIs prioritize user privacy through transparent consent mechanisms. Users are explicitly informed about what data is being accessed and for what purpose, empowering them with control over their data. From a cost perspective, APIs offer a scalable and predictable SaaS pricing model. Businesses avoid the upfront and ongoing costs associated with hardware, shipping, and device management, leading to significant cost savings and improved operational efficiency.
In conclusion, while OBD2 devices serve valuable diagnostic purposes, they fall short as a reliable and scalable solution for mileage verification. The inaccuracies, inconveniences, tampering risks, privacy concerns, and costs associated with OBD2 trackers make them a less-than-ideal choice for businesses requiring precise and dependable mileage data. Connected car APIs, on the other hand, offer a superior alternative, providing accurate, user-friendly, reliable, private, and cost-effective mileage verification. For businesses seeking to optimize their operations and build trust with their customers, embracing connected car APIs is the clear path forward.
