  • Easy to use, informative, and a great tool for do-it-yourself mechanics.
Great diagnostic tool, it simply downloads your vehicle information and works! It is capable of pairing key fobs, and diagnosing engine codes. After identifying the engine codes, it proceeds to provide links to help the user better understand the problems and identify possible ways to fix them. Its easy to use, simply plug the device into the OBD-II port under the drivers console, install the app on your phone, follow the instruction to pair bluetooth, and diagnose your vehicle. Its saved me a lot of money by allowing me to identify problems and fix the ones that I am able to resolve on my own. ... show more

  • Best little scanner for resetting Subaru learned values
This scanner saved me thousands as the Subaru dealer wanted to swap out my ecu for a P0017 code on my 21 Ascent. I went into test mode on the vehicle and looked at my vvt learned values. One of them was through the roof causing the error code. The dealer charged me $750 to change the oil control valve that was bad. Instead of reseting the learned values to fix the problem tbey wanted more money. They wanted to change the other 3 sensors to see if that would clear the code. Keep in mind, they already know it won't as they want to suck out all your money. I changed the 3 sensors and was able to clear the code while in test mode which zero'd out my learned values allowing the new senaora to be read and values learned on the ecu! Awesome little tool! Wish the company would send me another model to test! ... show more

  • One of the best purchases I've made
This scanner is perfect for a DIY'er. Way more than a generic OBD2 scanner. Capable of live data graphing and bidirectional control of the various modules within the vehicle. Connects to your phone easily and small enough to keep in the glove box.

  • Doesn't work as advertised.
I too considered the negative reviews and decided to try anyway. I emailed ThinkCar and got confirmation that I could do a 2008 Prius ABS brake bleed and linear offset relearn for our ABS actuator replacement project (yes, the $1200 part, or the $2700 repair at your local shop). It can be done. The mechanial part is actually not hard, just tedious and time consuming. It's the post repair configuration that gets you. I noted in the product FAQ's that functions were not as "robust" on IOS, so I purchased an Android tablet. Software would not install, said incompatible. First flag. Installed software manually on the tablet no issues. Initialized the software for Toyota and successfully registered and connected to car. Proceeded to run the ABS brake bleed but it would not finish successfully, crashing at various points or finishing "unsuccessful". Four hours of retrying and searching for answers, no luck. No online support, email or phone only during work hours m-f. Not taking a day off to get the runaround as described in other negative reviews. We then proceeded to use the mini vci cable and cloned tech stream software also purchased off Amazon. (Which involved building a windows 7 pc for compatibility, and downloading an ancient copy of tech stream from a forum because the software included in the Amazon product was bogus.) Which, believe it or not, actually worked. There are other required functions in order to actually complete the job: resets, clear the various DTC's due to the system being dissembled, and a final reset to clear the brake, abs and vsc dash lights, which I'm not sure the ThinkDiag could accomplish, never made it that far. This seems like a great product for DIY work. Affordable at $135, a great advantage over other products - which there appear to be none. I spent several hours and contacted several vendors trying to find a diagnostic scanner to do this work and it appears there are none, save the several thousand dollar commerical products, or possibly the Harbor Freight scanner at $900. Sorry folks, very enticing but not ready for prime time. ... show more
