There’s a user who loves its some most outstanding features. Here’s his sharing about his experience with Launch THINKDIAG:

My favorite feature of this tool is its small size and convenience to use. I can carry my Thinkdiag in my pocket, plug it in a car, then it will run a report, which I can check at my convenience. Two years ago, I bought my daughter a car. It ran well and looked good, no CEL, so I decided to buy it. A year later, at emissions inspection time, it failed. The actual LED for the CEL had been removed, the gauge cluster had been changed and the odometer was incorrect. If I had a ThinkDiag tool that day, I’d have found out the problem and reported the seller for fraud. Besides, the product comes with a free subscription for two manufacturer software packages for a year (during the discountable period). If you need more, the cost is $39.95 per year. The subscription gives you access to all diagnostic functions, including the ability to read & clear codes, access live data streaming, perform actuation tests and use all service functions of the manufacturer’s own software.



Now here’s my second-most favorite function. That is the diagnostic report can be downloaded and saved as PDF, which you can share to others and let them view the data from your car directly.
What’s more, it can actuate the ABS computer and perform an ABS brake flush/bleed without taking my car to the dealer.

He also listed the supported functions and diagnostic systems with a subscription to Nissan software:

Functions: Maintenance Functions, Remote Diagnostics, Special Function Actuation Tests, Read Fault Codes, Clear Fault Codes, Read Data Stream

Diagnostic systems: Accelerator Pedal Position Sensor, Active Engine Mounts, Active Noise Cancellation, Blind Spot Warning, Body Control Module, Combined Charging System, Controller Area Network Gateway, Electric / Hybrid Vehicle Systems, Electric Motor Condition Monitoring, Steering Column Cont Module and many more.

Some other reviews collected:

From Acadia Tom:

That it does a deep dive into all of the separate systems on the Acadia. It’s also a bidirectional control which gives ability to raise and lower windows, mirrors and gobs of other devices from thw phone. It works great in determining if a switch is broken.

The disadvantage is that some functions are add-ons, such as marrying new keys and fobs, ABS bleed, maintenance resets, etc. But buying the function you need is cheaper. Overall, it’s a very useful tool.

From Jay:

It looks like a pretty decent and useful device. And not overly expensive even though certain functions are sold piecemeal.

From Roy:

This is a great tool for the DIY automatic mechanics that need to troubleshoot and isolate fault codes. You get one free vehicle software, then the license for that software needs to be renewed each year for a subscription price. Considering the price of other scan tools, it’s very well worth the money.

From Bearsy72:

Used it to on a 2013 Chevy Sonic to test the cooling fans low and high speeds. It was easy to use and worked great! I like that they give you two brands for free for the first year. I chose GM and Ford.

From J&G:

Pros for THNKDIAG:

  1. The price is cheap.
  2. I was able to see data that my cheaper scanner couldn’t do.
  3. Performs true bi-directional testing!
  4. Downloading the app and setup was very easy.
  5. Connecting to the device from my smartphone via Bluetooth and was easy too.


  1. You get two makes for free for one year then you have to subscribe.
  2. This thing is not as fast as the pro scanners. This is not an issue for me as I am not doing this for a living.
  3. When I first started using it the bluetooth connection dropped several times. But after several attempts I had no further issues with it. I was sitting in the driver’s seat very close to the ODB port so I’m not sure what the issue was.
