Thinkdiag OBD2 Bluetooth Bidirectional Tool

This Thinkdiag device is amazing! The item was well packaged and also fits in a some sort of a cushion inside the box. It appears to be strong and connects flawlessly. I Installed the Thinkdiag+ app, created an account, and activated the device with the information included in the box. Then, I plugged the device in the OBD port of my car and I was able to see things that I did not know existed even though there is currently no CEL on my car dashboard. I was able to know exactly which tires are responsible for the TPMS light and also the state of the batteries and sensors. I also looked at some live data for my evap system and graphed some of them for better understanding. The Thinkdiag showed that the O2 sensors are working just fine and that the catalytic converter may be failing. The tool even showed the temperatures in and out of the catalytic converter which is very important in knowing its efficiency. I did not notice any connection issue and the speed was good in my case. This tool can be for beginners, intermediate, or advance DIYers. If you are new to this, take time to read the messages that appear on the screen when you request a function. If you are not sure, just don’t continue and go do some research on the topic if needed since this device gives you advanced access to your car vehicle computer. I think this is money well spent and its cost is actually less than the diagnostic fee from any dealership. This device can actually program additional keys for your vehicle and remove old keys depending on which car you drive. If you own a Honda or a Toyota, you know how much it costs for an extra key from the dealer. All in all, I think buying this device was a good investment even if you use it for one or two car diagnostics or simply to program a key/remote. The only downside is that there is a subscription fee after the free year for the reset services and the systems. If you don’t renew, the reset functions and all systems will go away, but you will still be able to use the OBD function and even see some live data. The renewal options are not very clear or efficiently structured in my opinion. It is as if it would make more sense to get another device with a free year instead of renewing the full package. Even the cost to renew one reset service seems a little overboard in my opinion, but I trust that they know what they are doing and I am not trying to tell them how to run their business. If this was an option, my rating would actually be 4.5 out 5 because of that. However, the device performed well and it provided me with the info needed. Depending on your needs and how much you know or willing to learn about car data, this may be a good tool to have in your glove box.
