TOPDON TopScan Lite OBD2 Bluetooth Scanner, Bi-Directional All System Diagnostic Tool with AI Assistant, 8 Resets, Repair Guides, Performance Test, FCA AutoAuth & CAN-FD for iOS Android

I am reviewing this for one vehicle at this time, a 2007 Subaru Forester X. I will get into the details about that in a bit but let's get general. It's free for the first year, but if it's still being used and you can catch a sale... But be smart, you can make another email. I would just buy a new unit on sale for like $60, BAM! You just got a new unit and another year. Some may be upset about the limitations, but let's be honest if it works for you it is still by far the cheapest I've found to do ANY bidirectional kung fu. It's ui isn't great, but poke around and you can get a hold of quite a bit. It will scan for your VIN, and then your model range or exact year. You can put it in manually but it finds mine quick so I haven't tried it. From what I see you need to scan the "BCM" or mini computer of each part. So you scan the main ECU and it will give you the general things which is pretty limited for me. It does offer many different cars and you download each individual car's database. So for my SUV it's old, but it does what I need. Kinda. So my main reasoning was the difficulty in getting my throttle body to relearn itself properly. It has an easy procedure if your A/C system is good, mine is not. Topscan says it can do the throttle relearn, but it simply gives instructions to restart, run for 10 seconds and it's done. It is not indeed done, nothing changed. The magic is to control your idle, which was why it needs to relearn the throttle but since that didn't work eventually if it's driven enough and isn't dying at every stop it relearns itself. So the trick is there is an idle adjustment. It's in a separate section, but it is rudimentary yet it'll do. So it starts off at whatever rpm your engine is by 25. So it tells me it's at 825rpm... It lies my tach an loping motor says under 600rpm. So here's what you do, there's the ability to add or subtract in denominations of 50 but the RPM accuracy isn't great so here's what I did. I put mine up to 1075 RPM and you press start. I believe it won't stop until you press the stop button. It 100% keeps my car from dying when coming to a stop or just any time the clutch is in and I'm not adding throttle it died in the before time, so last week. It's only been about 30 miles, so just to and from work so it hasn't learned itself yet. So Topscan... Again for me it's doing what I want, but it does seem kind of lacking otherwise. However, it's still all the stars because there is nothing comparably priced with the features. This ain't no mechanics thousand dollar scan tool, but for me I just remember... $60 vs $600-1200, SOLD! It can act like a normal code reader and such too, but here's why it's worth the extra $40 over an ELM327, it read and cleared my airbag code! Granted it came right back, but now I know it's my driver's airbag or the wiring for that one in particular. How much would a shop charge just to tell you that? Idk in this economy but less than that scanner & a year of big boy scanning included. Download the app before you buy, add your car and see what it will let you do for your car. I did and am not looking back! In a newer or different car it may be so much easier, but this is not simple for me at least. Totally worth it.

First make sure you understand this comes with basic functions, You need to purchase a yearly Subscription for your needs, Secondly this allows you to do a lot of functions that only a shop can do, So if you are mechanically minded this is a awesome tool, also if you want to do key fobs you can, but you have to purchase that Subscription though the online mall, most other scanners of this type are not bi directional, so for a cheap price and your phone as the monitor and a subscription you go from a man with tools to not paying a shop to diagnose, or do resets of multiple items.

I don't remember who recommended me to purchase this thing. But it's such a crap omg. Not only you don't get that first free one year subscription (I've payed additional $50 for that subscription). But it also works very, like very bad. In short: 1) The app requires internet connection. You cannot use it without signing in, and it's an issue cuz it will drop your login session once in a while. And I don't have a stable WiFi connection in my garage, and it's such a PITA to use this app. 2) There's not all car brands. It works for Subaru, and for Mitsubishi. But there's no Lada (which is basically rebranded Renault). Like any no name $10 OBD from AliExpress will have that car brand supported. But not TopDon TopScan for $80 + $50 subscription. Oh my gosh. Double check if you're car brand is supported. 3) I've tested it with Subaru WRX STI 16", because I did a coolant flush and all I needed is to watch coolant temperature graph (when burping, in order to see when thermostat was opened/closed). But no matter what I do, there's no such data in TopDon. Be sure I've spent hours trying to find that information. Such a simple task cannot be done with TopScan. 4) Issues with connection. For some unknown reason, TopDon TopScan DOES NOT connects to your car. And sometimes it can't auto read VIN number. When it happens, you must enter your VIN manually. The connection is also very unstable, even if you're like in 1 meter away. 5) Eventually, it did not helped me. Thanks god I had a no name OBD from aliexpress, that I've purchased years ago for $10 or so. I've connected that thing instead of TopScan, and it successfully connected in a matter of seconds. That old no name OBD automatically read my VIN, detected the car brand, and just worked. I've had to click literally 2 buttons to access Coolant Temperature graph (updated in real time). By the end of the day, I was so disappointed. Maybe it's a good product for things like ABS brake bleeding etc. idk. Just sharing my experience, so you understand what you should expect in reality. Total waste of money and time.

Update: The product is actually really good. Despite their support bs, I decided to try it. I could still return it if I wanted to within 30 days. It got a ton of tests and a bargain at its price point and the 50 dollars a year. I change my review to 5 stars on the product but left the company review at 1 star. I would say if you are looking for a basic OBD2 reader skip this one and get a regular one. But with this little thing you can active test any supported item. I feel like I do enough home mechanic projects this will work for me. **** I bought this taken in by its cheap price. I went back a day later and noticed that it was a subscription based product after the first year. I want to point out that the subscription part was labeled on listing clearly, it was my mistake for not seeing it originally. I contacted the company asking what would be lost if I didn't pay for the yearly subscription as I thought it was werid to pay 50 dollars for the device then 50 dollars each year to keep it going. The exact email I got back was : "the topscan is a very capable tool in the right hands. well worth the subscription fee if you work on cars often. its comparable to much much higher level scan tools in terms of capability. if you cannot justify 100.00 dollars than maybe its not the tool for you. You can return it." I thought that was a smart aleck email so I replied back that sounded rude and I just asked what I would lose if it didn't work. After several back and forth emails I got this this in an email: "Seems as though your mind was already made up so what can I do? You lose all bidirectional features and online functions after your subscription is up. It turns into a super basic OBD2 code reader." My mind was never made up. I was just stating that I was trying to figure out the justification for 50 dollars extra per year. I was weighing out my options as to if I would pay the 50 dollars per year or just let it go to its no subscription version. I called their sales team which the person I talked to was like "yeah...thats a pretty straight forward question. Not sure why you got that reply". He supposed to have sent it to the supervisor and I didn't hear back. So they will be receiving this back unopened and returned.

I loved my OBD2 scanner.. and then someone stole it out of my truck.. The Bluetooth connection was quick and the data was easy to understand. It worked great for my ram 1500

I purchased the TopScan to help diagnose an intermittent drivability issue that wasn’t setting a consistent fault code. Using the live data functions, I was able to monitor sensor readings and narrow the problem down much faster than I could with a basic scanner. The bidirectional controls and data stream features were surprisingly capable for a tool in this price range. It paid for itself on the first repair and has become a regular part of my troubleshooting process. Great value and easy to use.

I bought this scanner for bi-directional controls, and to abs bleed my 03 Suburban Lt 5.3 Vortec that has a spongy brake pedal even with new lines, and MULTIPLE SHOPS ABS BLEEDING WITHOUT ANY IMPROVEMENT! They say it's the abs module underneath, which we replaced and still it happens. So the fix is, that they UNPLUG MY BRAKE SWITCH off the reservoir to eliminate the warning light on the dash. I CAN'T SELL MY CARS LIKE THAT. That should be illegal, and my name means you get quality products and service from me always. So I get this scanner to DIY myself and tinker with the abs bleed function. At first the scanner DIDNT WORK?! NO POWER OR ANYTHING! I figured maybe charging issue? Nope, doesn't need charging. So now what? My trucks and 03 suburban Lt with the 5.3 flex fuel engine and it's not reading the port. No power at all! Truck runs great! But the one cigarette lighter is dead and I get random warning lights but I'll clean grounds and issues fixed. Also my trucks brake light warning comes on and feels spongy at times and I replaced all lines and had multiple shops bleed and abs bleed Common issues with these trucks. So is the scanner bad?! Well I test my mom's 2013 f150 fx4 Ecoboost 3.5l crew cab. DEVICE TURNED ON INSTANTLY. Happen to find out her tpms was BAD and her tire was at 16psi. (Her truck doesn't have the live tire reading info like most vehicles offer). We would have had to test each tire for a reading instead of having this tool. Found a nail. Cool I'll plug it in no time with my Amazon tire patch kit. TESTED THE BI DIRECTIONAL CONTROLS, HERE IN HER TRUCK, it worked AMAZING! Tested locks and windows well as horn. It's so awesome! Next is my GFS 2015 crv ex. Scanned her car with no issues Go back to my truck, and I figured my obdii port is dead? Check my fuses and the cigarette lighter fuse was blown. So I replaced it immediately. Also plugged my brake switch in, that they unplugged after giving up. Guess what..... PORT WORKS NOW?! Scanner works INSTANTLY. I test and find 20+ faults. All with the transfer case, the door switch module, the bcm not reading modules anymore, etc. My brake warning light, GONE. So I take it for a test drive. BRAKES ARE SOLID NOW. Wtf ?! No issues there. Like new brakes. Cigarette lighter works now. Between the Brakes being fixed, the obd port being fixed, my parents tire got fixed faster, I learned all the issues I gotta kink out on my car and i can actually live data read and ACTIVE TEST each module! The insight I can pull on cars within seconds is astounding! THIS IS MY NEW FAVORITE DEVICE!! I WANNA BUY EVERY CAR EVER MADE AND FIX EM. Well worth the $50 I got it for. Hands down. I feel like a master mechanic. I easily saved multiple trips borrowing scanners, or paying to have codes scanned and two hours of them tinkering, now I save all that moolah and they can't charge me since I GOT MY OWN TOOL NOW! WELL WORTH ITS PRICE, EVEN AT $89 IT WAS BEFORE MY DISCOUNT! I WAS JUST LUCKY TO GET A DEAL! NOT SAYING BUY IT, BUT ID HIGHLY RECOMMEND YOU GET ONE. THANK YOU TOPDON FOR A JOB DONE WELL!!

It worked great for the first year. Then it turns into a subscription based model. which I guess I can do but isn't ideal. The real problem is that their software doesn't work when you try and subscribe. For me it was stuck in "subscribing" state. I had purchased the subscription. They charged my card. They couldn't be bothered with actually honoring the service. The customer support sucks. Good tool and app when you can use it.

If you are looking for a versatile and affordable OBD2 scanner to troubleshoot and fix your car problems, you might want to consider the Topscan OBD2 scanner. This is a wireless Bluetooth device that connects to your phone and allows you to access a wide range of features and functions through the app. You can scan the full system of your car, live data information, send commands to the car’s ECU for active testing, measure the performance of your car and get guidance on how to repair the faults. The device supports most vehicles produced from 1997 to 2022 that comply with the OBDII standard. When I plugged in to a 2003 Audi, I was surprised that it did an auto VIN to read the ECU which my previous dongle didn’t do where I had to search manually. The device is very well-built and sturdy, and it feels like a professional tool. It comes with a one-year free software update, which is a nice bonus. The app is easy to use and navigate, and it provides clear and detailed information. The device and the app work together seamlessly, and the Bluetooth connection is fast and stable using my Samsung Android phone. With the tool it found that the status LED light very useful which showed the power, bluetooth connectivity and a status/communications light. One thing to note is that when you plugin in the device to a vehicle, you will need to download the corresponding vehicles database/packages to the app which did take around 15 minutes on my connection. I think this is a fantastic OBD2 scanner for the money and the features. It does more than my previous dongle I used to use and it helps me save money and time on repairs in the longrun. I would recommend it to anyone who wants to do their own car diagnostics and maintenance or even understand faults that arise on vehicles before they take to a garage. I will keep reviewing this on other makes and models and see how I get on with those. I will update this review where required.

EL TOPDON TOSCAN funciona de lujo, lo conectas al puerto OBD abres la app y en segundos te lee los fallos. Explica los códigos de forma clara, incluso si no sabes de mecánica compatible con muchísimas marcas de coche y va super rápido. Me ha ahorrado varias visitas al taller. Muy recomendable para tener en casa.

Perfect as described

Es algo complicado de instalar y de usar las primeras veces. Tiene mucho soporte para muchas marcas de coches, pero si recomiendo ver un tutoríal o algun unboxing para entender varias de las funciones, que incluso con practica a veces es algo complicada pero en general es un gran escáner y tiene soporte y garantía. Consejo revisa si tu teléfono que usaras para conectar el scanner es de 64bits en Android, porque la app no es compatible para sistemas operativos de 32 bits.

PRO 🙂: buon software - compatibilità con Smartphone - molte funzioni disponibili - risolve alcuni problemi. CONTRO 🙃: alcune funzioni possono non essere compatibili con l'auto. Ho usato questo obd per esplorare le funzioni aggiuntive della mia auto, valutare alcuni dati e sbloccare alcune funzioni. È un obd compatto, ho apprezzato il software android, che funziona bene e ben leggibile. Tutto in italiano. 🚘 Ha molte funzioni, l'accesso a molti controlli. Nella mia auto non ho l'accesso a alcune funzionalità perché bloccate dalla centralina, o perché non esistono, ma si possono leggere molti dati e impostazioni nascoste. E posso azzerare alcuni errori. Probabilmente in base all'auto e alla centralina si possono o meno sbloccare determinate funzionalità. Può essere utile per appassionati di meccanica o per chi come me si occupa della manutenzione della propria auto. 👍
