Choosing the right OBD2 scanner can feel overwhelming, especially with the vast array of options available today. If you’re diving into vehicle diagnostics, you’re likely asking, “What Are The Best Obd2 Scanners?” It’s a crucial question because the right scanner can save you time, money, and a lot of frustration when dealing with car troubles. Whether you’re a seasoned mechanic or a DIY enthusiast working on your personal vehicles, understanding the landscape of OBD2 scanners is essential. This guide will explore what makes a great OBD2 scanner, focusing on features, functionality, and value, using the popular Thinkdiag as a key example to illustrate the points.
Understanding OBD2 Scanner Functionality
At its core, an OBD2 scanner is a tool that communicates with your car’s On-Board Diagnostics system. This system monitors various aspects of your vehicle’s performance and emissions. When something goes wrong, the system generates diagnostic trouble codes (DTCs). An OBD2 scanner reads these codes, giving you a starting point for diagnosing the problem.
However, not all OBD2 scanners are created equal. Basic scanners might only read and clear engine codes, while more advanced tools offer bidirectional control, allowing you to command the car to perform tests and functions, like activating ABS or performing a TPMS relearn. The “best” OBD2 scanner for you depends heavily on your needs and expertise.
Thinkdiag: A Deeper Look into a Popular Option
Thinkdiag has emerged as a compelling option in the OBD2 scanner market, particularly for those seeking more than basic code reading capabilities without breaking the bank. It’s known for offering bidirectional functionality at a more accessible price point compared to traditional professional scan tools. A common question surrounding Thinkdiag, and similar scanners, is the subscription model. Let’s break down how it works.

Thinkdiag utilizes a subscription system to unlock advanced features beyond basic OBDII diagnostics. The fundamental OBDII functions – reading and clearing generic codes, viewing live data related to emissions – are typically available without an ongoing subscription. This means even without paying extra, you can use it as a basic code reader indefinitely.
For more in-depth diagnostics and bidirectional controls, Thinkdiag offers a flexible subscription model. You have a couple of primary options:
-
Manufacturer-Specific Subscription: For roughly $39.99 per year per car manufacturer, you gain access to all diagnostic functions, including advanced features and bidirectional controls, for vehicles of that specific brand. For instance, subscribing to the “Kia” manufacturer pack would grant you full diagnostic capabilities for all Kia vehicles for a year. Importantly, this subscription is per manufacturer, not per vehicle. If you work on multiple Kias within that year, the single subscription covers them all. Thinkdiag often includes one free manufacturer subscription for the first year with the initial purchase. Note that some premium brands, like Tesla, may have different pricing.
-
Function-Specific Subscription: Alternatively, you can opt for a function-based subscription. For around $49.99 per year, you can unlock a specific service function, such as ABS actuation or TPMS relearn, across all supported manufacturers. This is beneficial if you specialize in a particular type of repair or service, regardless of the vehicle brand.
Thinkdiag also frequently provides an attractive “all-makes, all-functions” annual subscription, typically around $129. This unlocks the full potential of the tool for all supported vehicle brands and functions for a year, offering comprehensive diagnostic coverage.
If your subscription lapses, access to the advanced functions and bidirectional controls is suspended until you renew. However, the basic OBDII functions remain operational.
This subscription model is designed to cater to different user needs. DIYers working primarily on their own vehicles can subscribe only to the manufacturer(s) they need. Professional technicians can choose between manufacturer-specific subscriptions, function-specific subscriptions, or the all-encompassing package depending on their specialization and workflow.
Comparing Thinkdiag to Other OBD2 Scanners and Subscription Models
The annual fee structure of tools like Thinkdiag is a departure from traditional OBD2 scanners that often involve a higher upfront cost but no recurring fees. However, when considering the total cost of ownership, especially for advanced diagnostic capabilities, Thinkdiag can be quite competitive.
Comparing Thinkdiag to more established professional scan tools, such as those from Launch, is insightful. Launch scanners, while highly capable, often come with significant upfront investments and also require annual update fees to maintain functionality and coverage for newer models. In this context, Thinkdiag’s subscription model can be seen as a more budget-friendly way to access similar levels of diagnostic power, especially for users who don’t require daily access to every manufacturer and function.

Choosing the Best OBD2 Scanner for You: Key Considerations
When determining “what are the best OBD2 scanners” for your specific needs, consider these factors:
- Budget: OBD2 scanners range from very affordable basic code readers to professional-grade tools costing thousands of dollars. Define your budget upfront.
- Diagnostic Needs: Do you primarily need to read and clear engine codes, or do you require advanced functions like bidirectional control, module programming, and access to manufacturer-specific diagnostic data?
- Vehicle Types: Do you work on a specific brand, a range of domestic vehicles, or a wide variety of makes and models, including European and Asian vehicles? Ensure the scanner you choose offers sufficient coverage for the vehicles you’ll be working on.
- Subscription vs. One-Time Purchase: Evaluate the long-term costs of subscription-based scanners versus the upfront investment of traditional scanners with update fees. Consider how frequently you’ll use advanced features and whether a subscription model aligns with your usage pattern.
- Ease of Use and Features: Look for a scanner with an intuitive interface, clear display, and features that simplify your diagnostic workflow, such as data logging, graphing, and automatic vehicle identification.
Conclusion: Finding Your Ideal OBD2 Scanner
The “best” OBD2 scanner is subjective and depends entirely on individual requirements. For users seeking a balance of advanced functionality and affordability, particularly those comfortable with a subscription model, Thinkdiag and similar tools present a compelling option. They offer a pathway to professional-level diagnostics without the hefty price tag of traditional high-end scanners.
Ultimately, answering “what are the best OBD2 scanners?” requires careful consideration of your budget, diagnostic needs, and the types of vehicles you’ll be working on. By understanding the different types of scanners, subscription models, and key features, you can make an informed decision and choose the tool that best empowers you to tackle automotive diagnostics effectively.
