Standout Features of the THINKCAR Thinkscan 672
The core of this scan tool relies on an MT8365 CPU with a 2.0GHz Cortex-A53 quad-core processor. The listed specifications indicate it includes 32GB of ROM, providing adequate storage for diagnostic software and data reports. Users interact with the device through a 7-inch widescreen display featuring a 1024×600 resolution.
Beyond basic code reading, this tool supports bidirectional control, allowing users to send direct commands to the vehicle’s ECU. The manufacturer notes it includes 28 specific reset services, such as oil resets, SAS calibration, and ABS bleeding. It also supports the CAN FD protocol natively, which is crucial for communicating with newer GM and Chrysler networks.

Best For — and Who Should Skip It
This diagnostic scanner is ideally suited for DIY mechanics, weekend tinkerers, and small independent shop owners. The inclusion of lifetime free software updates makes it highly attractive for buyers who want to avoid recurring annual subscription fees. It provides enough depth for routine maintenance, component testing, and module resets without breaking the bank.
Professional technicians working in heavy-duty diesel shops or those requiring advanced ECU programming should likely skip this model. While it offers injector coding, the specifications do not indicate support for deep module flashing or specialized immobilizer key programming. Buyers needing a fully wireless VCI might also find the 1.2-meter physical diagnostic cable limiting.
Day-to-Day Performance Expectations
Setting up the scanner involves connecting to a network via the built-in dual-band WiFi to download the latest vehicle software patches. Power is supplied by an internal 3150mAh 3.8V battery, which the manufacturer claims supports extended diagnostic sessions away from a charger. For vehicle communication, the tool relies on a detachable 1.2-meter DB15 cable, requiring the user to remain inside or immediately adjacent to the vehicle cabin.
When utilizing active tests to actuate components or performing functions like ABS bleeding, users must exercise caution. Moving mechanical parts and pressurized hydraulic systems present inherent physical hazards in the shop. Always consult the specific vehicle’s factory service manual and follow qualified service procedures before initiating bidirectional commands.
How It Stacks Up Against Alternatives
When evaluating options within the same brand family, buyers might consider the THINKCAR ThinkScan 689BT diagnostic tool. The 689BT typically represents a higher-tier model for users seeking advanced wireless connectivity, whereas the 672 relies on a physical DB15 cable for direct vehicle communication. Both tools share similar menu structures, but buyers should confirm the current configuration to ensure it meets their mobility needs in the garage.
Another closely related alternative is the ThinkScan 662 bidirectional scanner, which offers a comparable feature set within the ThinkScan lineup. For those cross-shopping outside the brand, the Launch X431 CRP919X diagnostic scanner provides an excellent alternative with a similar diagnostic software heritage. While the Launch variant may offer slightly different vehicle coverage nuances, the Thinkscan 672 stands out primarily due to its aggressive price point and lifetime update promise.
Common Buyer Questions
Does this tool require a yearly subscription for software updates?
No, the manufacturer specifies lifetime free software updates for this model. Users simply connect the device to Wi-Fi to download the latest vehicle coverage patches.
Can it read and clear codes on all vehicle systems?
The listed specifications indicate full-system OE-level diagnostics. This comprehensive coverage allows the scanner to communicate with modules like the ECM, ABS, SRS, EVAP, and TPMS.
Does the scanner support newer GM vehicles?
Yes, the device natively supports the CAN FD protocol. This modern communication standard is essential for diagnosing newer GM, SGM, and Chrysler models accurately.
How do I access FCA AutoAuth for 2018+ Chrysler/Dodge/Jeep vehicles?
The tool supports FCA AutoAuth bypass software. However, buyers must register for an FCA account and pay the required membership fee directly to AutoAuth to unlock the gateway.
Is this scanner completely wireless?
While it features Bluetooth 5.0 and dual-band Wi-Fi for updates and data transfer, vehicle diagnostics are not wireless. The unit relies on the included 1.2-meter detachable DB15 cable to connect to the OBD2 port.
For the 2026 diagnostic market, this scan tool presents a compelling balance of bidirectional functionality and long-term value. The lack of subscription fees combined with CAN FD support makes it a highly practical investment for home garages and independent technicians. Buyers should verify their specific vehicle compatibility, but for general multi-brand maintenance, it is a recommended purchase.
