For car enthusiasts and professional mechanics alike, having a reliable OBD2 scanner is indispensable. When it comes to comprehensive diagnostics, a full system OBD2 scanner is a must-have tool. Among the various options available, the Thinkdiag scanner often comes up in discussions, particularly regarding its capabilities and subscription model. Let’s delve into what makes Thinkdiag a contender in the realm of full system OBD2 scanners and address some common questions about its functionality and cost.
Understanding the value of a full system OBD2 scanner starts with recognizing its breadth of access. Unlike basic OBD2 scanners that primarily read engine and emissions-related codes, a full system scanner can access and diagnose virtually all electronic control units (ECUs) in a modern vehicle. This includes systems like:
- Engine Control (ECM): For powertrain diagnostics, fault codes, and live data.
- Transmission Control (TCM): For transmission issues, shifting problems, and related codes.
- Anti-lock Braking System (ABS): For brake system malfunctions, sensor issues, and ABS light diagnosis.
- Supplemental Restraint System (SRS/Airbag): For airbag system faults and safety-related concerns.
- Body Control Module (BCM): For electrical system diagnostics, lighting, windows, and accessories.
- Climate Control (HVAC): For air conditioning and heating system problems.
- Instrument Cluster: For gauge issues and dashboard errors.
- And many more: Depending on the vehicle make and model, a full system scanner can access numerous other modules.
The Thinkdiag scanner stands out by offering these full system diagnostic capabilities in a relatively compact and user-friendly package. It connects to your smartphone or tablet via Bluetooth, turning your mobile device into a powerful diagnostic tool. Beyond just reading and clearing diagnostic trouble codes (DTCs), Thinkdiag boasts bidirectional capabilities, allowing users to perform active tests, control modules, and execute special functions.
However, a key aspect of Thinkdiag, and where many users have questions, is its subscription model. It’s essential to clarify how the subscription works to understand the true cost and functionality of this scanner.
Thinkdiag’s advanced features beyond basic OBDII diagnostics operate on a subscription basis. This means that while the fundamental OBDII functionalities for engine and emissions diagnostics are perpetual, accessing advanced features like full system scans, bidirectional controls, and special functions requires an active subscription.
Thinkdiag offers a couple of subscription pathways:
-
Manufacturer-Specific Subscription: For users who primarily work on vehicles from a specific manufacturer, Thinkdiag offers annual subscriptions per car brand. For roughly $39.99 per year for a single manufacturer, you unlock all diagnostic functions for vehicles of that brand. Importantly, the initial purchase of a Thinkdiag typically includes one free manufacturer subscription for the first year. For example, if you subscribe to the “Kia” manufacturer package, you gain full system access, bidirectional controls, and special functions for all Kia vehicles within that year. This subscription, however, would not extend to other brands like Hyundai or Ford unless you purchase separate subscriptions for those manufacturers.
-
Service Function Subscription: Alternatively, for technicians who need specific service functions across various makes, Thinkdiag provides subscriptions to individual service functions. For around $49.99 annually, you can unlock a particular service function, such as ABS bleeding or TPMS relearn, for all supported vehicle manufacturers. This can be cost-effective if your diagnostic needs are focused on specific procedures across different car brands.
-
All-Makes, All-Functions Subscription: For comprehensive coverage, Thinkdiag often provides a promotional “all-makes, all-functions” annual subscription, typically priced around $129. This option unlocks all diagnostic capabilities across all supported manufacturers and all service functions for a year. This is often the most appealing option for professional technicians or workshops dealing with a wide variety of vehicles.
It’s crucial to understand what happens when a subscription lapses. If your Thinkdiag subscription expires, you will retain the basic OBDII diagnostic functions, which are free and do not require a subscription. However, access to manufacturer-specific full system diagnostics, bidirectional controls, and special functions will be deactivated until you renew your subscription. Upon renewal, you regain full access, and importantly, your subscription ensures you receive software updates, including coverage for newer vehicle models and newly added functions.
When considering the cost of Thinkdiag, it’s beneficial to compare it to traditional professional scan tools. High-end scan tools from brands like Launch often come with significant upfront costs and also require annual update fees to maintain coverage and functionality. In this context, Thinkdiag, with its subscription model, can present a more budget-friendly entry point into professional-grade diagnostics, especially for users who can strategically choose manufacturer-specific or service-function based subscriptions to match their needs.
Ultimately, whether Thinkdiag is the “best” full system OBD2 scanner depends on individual needs and priorities. Its subscription model offers flexibility and affordability, particularly for DIY enthusiasts or smaller workshops that can tailor their subscriptions to the specific vehicle brands or functions they frequently encounter. For those requiring broad, all-makes coverage, the annual all-functions subscription provides a competitive value compared to many professional scan tools in the market. If you are looking for a powerful, portable, and cost-effective full system diagnostic tool, Thinkdiag is certainly a strong contender worth considering.
