Professional Bi-Directional Diagnostic Scan Tool | GWSMARTBT | FREE Software updates, Supports 23 vehicle reset/relearn functions, Covers 185+ car manufacturers

Very solid unit for the price. Initial setup is quick and simple - mine on an Android based phone. Normal Play Store app install and then a few demographic entries for registration and license key activation. First use then goes into vehicle specific data downloads. Expect 5-10 minutes as this unit has compatibility with many vehicles makes and models. Once initial config of the app is done and the unit is plugged into the vehicle OBD port the app connected quickly. Once connected to the unit the app gives you the option of doing vehicle specific diagnostics either automatically or manually. The auto detect function worked well for multiple vehicles - BMW, 2015 and 2024 Subarus. Speed of the diagnostic scan depends on the actual vehicle as each of mine varies but all were extremely fast when compared to my other scanners (hardware and software based). The initial scan auto detects VIN, make, model, etc. and then scans all of the vehicle's available modules. Once scanned you can view a large amount of module parameters and states. A few examples - for the 2015 Subaru it was stated on a different forum that the GW tools do not have CVT fluid temp, which is key to proper filling procedure. Well, I can confirm that it does w 1/10th degree resolution. While I was in there, I was able to read and clear all errors across many modules. While in the transmission module, the BT unit has a broad number of good monitors for many different states (e g., shows live state of each gear) and a nice feature is it gives the normal value ranges for the numeric monitors. Just to check, I went into a few other modules and was please to see the same broad range of monitors (for example, live state of brake light switch) which makes troubleshooting and ruling out certain components so much easier. Unlike other scanners, you don't have to setup a data display screen to see every value. You do have the option to monitor the value trends and then generate a report. For the BMW, it actually has BMW error codes vs P codes and a large number of diagnostics when compared to my other BMW specific scanner. The unique item I wanted to try was the FCA Autoauth function which allows you to bypass the firewall on newer FCA vehicles (e.g., Fiat, Chrysler, Ram, etc.). Tried the unit in my 2019 Ram 1500 - unit auto prompts to enter an Autoauth account - I was able to quickly login w my Autoauth account and it was able to get through the secure gateway to do full diag and actuation - this is a big bonus. Aside from diagnostics, the unit has a robust set of functions that you can perform (of course these are vehicle specific). As an example, with a button push or two I was easily able to place the emergency brake in maintenance mode on all my vehicles with this unit. All in all, a pretty decent unit for the money especially for multiple makes. Of course this does not do what it isn't designed for - so it is not a programmer and doesn't claim to be. So for those with dealer lever tools (like ISTA for BMWs) this won't give you module layouts, troubleshooting plans or maintenance plans - but what it advertises itself as it did an exceptional job across my 4 different vehicles.

So there is a ton of options in today age with countless companies making diagnostic scanners now and I spent a lot of time researching and reading technical data and reviews for most Bluetooth scanners that are this style that uses ur phone and an app instead of a dedicated device and after all my research the GW pro , XTool A30m (identical to GW pro) and top don master were the ones I choose from. This being the cheapest of the 3 and With my experience dealing with Gear-wrench/ apex tools with their no hassle Stand behind their product without question customer support is why I choose this over the others. If the top don master was 50 bucks cheaper I would have bought it But hands down this GW pro can’t be beat for the money I spent. 110ish at the time of purchase. This thing is a treasure trove of information and to buy a dedicated scanner that does what this little device will do will cost you significantly more 2x-3x more easily. Now this thing has some features I really like. You can custom pick diffrent sensors and place them on a graph chart all together and something I have only seen a few high end scanners do. You can also click on a sensor and it will pull up a graph in live time of what that sensor is doing. It goes so in depth that I even had to look up what some of the info meant and iv been a professional tech for 5 years now. Now obviously this isn’t a dealer level tool but its not $3000+ either .The Bi directional control allows me to test way more things then a lot of info led on and really no reviews went in depth to how much this little device does. I could literally write for an hour and not cover a quarter of everything I have found and that’s just on two car brands so far in the 2 days iv had it and keep discovering more every day. Definitely recommend but be careful you can also seriously damage ur car with this thing to so be very careful and if you don’t know what something is DO NOT TOUCH IT.

I got this a while ago. I have tried using this on my 2016 subaru xv hybrid from Japan but it doesn't really scan it fully not able to read codes of the engine. I have also used it on my 2020 Mazda CX-30 with a VIN but it was also unable to scan the engine codes from that. The most useful thing we can get from it is the transmission codes and monitoring. Even the manual mode of selection doesn't really help. I have tried reaching out to the company for a while but no ones responds. So just be careful it may work with some vehicles but not all it seems.

For the money this little unit is great. it may be a little slow, but for the lifetime updates and the bidirectional control, this thing is worth twice the price.

I got this only a few hours ago. I have some mechanical training and a few years of wrenching. I was able to fix some issues that have been plaguing one of my cars. This Bluetooth dongle with its bidirectional capabilities allowed vsc reset, testing and actuation of a number of system actions. I can read the values of complex sensors in real time. Quite possibly the most important tool I have now. There’s a latency lag of course. Not as bad as some reviews I have seen online make it out to be. There is a learning curve with these items and it takes some persistence and a bit of resourcefulness to get the desired action. The layout is fairly intuitive but if you haven’t dealt with bidirectional capabilities before, you may end up googling and YouTubing left and right. I certainly did a fair share of it. The fact this has all the capabilities built in with NO subscription is the best feature. Some say there’s a connection issue and reconnect fixes it, I had no such issue using it for about an hour and a half getting to know it and using it. Connect Bluetooth through your phones settings menu and the app connects when you open it. Super excited TPMS not only reads all aspects of the system but you can rewrite to the computer the id of each sensor. True bidirectional features. I have at least 10 dongles, Bl**d***er was an except for mode 6. Even tried another brand Th***di*g and you have to pay for each and every bidirectional capability and for annual access to use the dongle other than obd2 code reading. Some special features just aren’t available with every vehicle and the app will tell you. Everything built in and free forever in this one. You can update and download certain functions or all of them. Firmware seems to be either auto upgrade or not upgradable at least at the moment. Wish list: -I do think maybe a pro and novice mode or added features could be very helpful. Novice to include tutorials and more in-depth instruction and information on the use of each feature. -Add mode6 reading as well. -As is, you select the special feature you want to use then select your car. It would be nice to select or auto select your vehicle first then all features open to you. It’s very time consuming with the UI as is. Learning the capabilities I was in and out of each feature multiple times trying difference iterations and reach and every time you must either auto select or manually select your vehicle over and over and over again. Another device I have operates in a similar fashion to my request and is markedly easier and faster to use. -decrease latency more. When you’re reading a bunch of values at the same time it is slow to show the initial values let alone update. Just a few at a time it is faster. I have a number of readers that a much faster than this one. Again I’ve only had this a couple hours. I’ll update as I get more use out of it Good or bad

This OB2 Bi-Directional tool is a great item to have for a DIY for any type of your cars you may have. Great comparability with my iPhone, good blue tooth connectivity. Functionality has easy use, did have to you tube how to do a few things, but over all this tool is AWSOME. Better details on any problem codes and has tons of options, more than I will use but I look forward to learn how to use this better. Bought this for my Subaru Legacy to relearn a transmission valve body to relearn after it I replaced it.

This tool does work. It does however have issues with newer vehicles and identifying them via VIN. General OBDII reads are fine though. The instructions and app for the phone are what leave things to be desired and where the reliability is shotty in my opinion. Would I recommend it? Probably not. Wild I say don’t buy it? Again, probably not. It’s a nice things to have but not something I would say go get it because it is going to work so well. It does receive frequent updates though, so that is nice they are keeping parts up to date

I always wanted a bidirectional scan tool like this but was looking for one that had lifetime updates, without any catches and could handle a wide variety of vehicles. When I heard that GearWrench was offering this model at such an affordable price, I knew this was the one. I owned GearWrench tools in the past and I was very satisfied with them so I was hopeful that it would be the case here. They did not disappoint. But let's talk about my experience in chronological order. Delivery was quick and on time. I installed the app on my Android phone (a 2025 Motorola Moto G Power) and attempted to connect the device to my 2021 Mazda6. It would not connect. I changed phones (Samsung A12) but that did not connect either. I reinstalled the app on the Motorola - nothing. I called customer service - nothing. I was considering returning it but decided to poke around a bit first. After a few minutes I got a prompt from the phone saying that I was to grant the app permission to access Bluetooth. I allowed it and voila - it connected! It has been smooth sailing thereafter. Works like a charm - for the most part. The first need I had of it was with my daughter's 2013 Mazda6. It came to me with a flashing airbag light. BT identified the problem as a passenger airbag module, but did not specify further. I attempted to clear the code to no avail. I attempted to reset the module, to no avail. At that point, I reached for my laptop, connected FORScan (a third party dedicated Ford/Mazda software) to the car and it was able to give me more details and was able to reset the module. I was a little disappointed that BT couldn't handle it, though. My next use of it came with my JDM Nissan Note X DIG-S. I had just done a transmission fluid and engine oil change and noticed that the Auto Stop/Start light in the instrument cluster was flashing and the feature was disabled. I reached for BT and it told me that the electric transmission fluid pump was experiencing low pressure of 0.5 MPa. That's supposed to be normal for the car at idle (according to the Nissan workshop manual) but the car and BT were saying otherwise. I wanted to reset the transmission module but I decided to leave it alone for now. It eventually cured itself. My latest use of it came a few days ago when a coworker's JDM Toyota Voxy had the dashboard light up with warning lights - typical for Toyota. I connected BT and it said that the vehicle had a number of issues including the ABS and the valve control system. I cleared the codes and all has been well since. Very strange, but BT saved the day. I haven't used all the features so far, but I believe it has the ability to put you on the right path if you ever encounter an issue, though it may not be able to solve it. I'm giving it 5 marks in spite of the issue with the airbag module, though. This is so because that feature may actually be a Mazda-proprietary feature that just was not available to BT as yet. I have done several updates since then so perhaps it is now possible. Pros: Updates are free for life Customer service agents available via phone Handles makes not even sold in the North America Cons: Bluetooth connection is slower than wired devices Unable to automatically detect any vehicle that I have connected it to (Mazda, Toyota, Nissan, BMW) It must be registered to only one phone at a time (customer service has to be contacted if moving to another) May not be able to reset all modules

Awesome little unit. Using it regularly and has allowed me to initially get workshop up and going with the added $1000's of a name brand high end scanner. Can't do everything but can do alot. Super happy

This scanner is by far the best one I’ve used for personal use, it has a bunch of features and scans every part of the car, from there it shows you a report of what’s wrong in an easy to use format. By far will most definitely recommend this to everyone I know.

Note que en 2 talleres de tres a los que llevé mi vehículo los escáneres eran incapaces de leer los códigos en mi auto, así que compré uno de la marca astro ai. Este tampoco pudo leer los códigos que están en el tablero. Así que compré este escáner, y resulta que sí es compatible con mi SUV. De hecho puedes descargar paquetes para trabajar con muchas marcas diferentes. Sí es algo lento, pero tampoco es algo que sientas que se te va la vida esperando. No he explorado sus funciones completamente pero tiene muchas funciones especiales, como TPMS, asientos, frenos, etc. A mí me sirve para resolver muchos problemas que ni en talleres profesionales me habían podido resolver, así que le doy 5 estrellas

La verdad muy bueno superó mis espectativas, muy fácil de instalarlo y darlo de alta. Entra a muchas marcas automotrices áridos los sistemas y tiene muchas funciones especiales. 10 de 10

Worked as intended
