CACAGOO OBD-II Diagnostic Scanner is a multifunction and high-tech diagnostic tool for OBD II protocols compliant vehicles. With its connected free Mini OBD II app and Wireless 4.0 / Wireless 2.0 dual-mode connection, it supports high-speed data transmission with low power consumption. You can get real-time sensor information and alerts right on your Bluetooth-enabled iOS or Android device. It helps improve driving performance, increase driver safety, improve fuel efficiency and reduce accident-associated costs.


What is OBD-II?

OBD stands for On Board Diagnostics and the number II refers to the second generation of these tools that were updated in 1996. CACAGOO OBD-II Car Diagnostic Scanner helps comprehensively exam the whole car, detect sub-health in time, find trouble codes earlier and warn you when a problem arises in your car. It also helps monitor the current and historical fuel consumption, analyze driving behaviors and offer suggestions.

Wide Compatibility
Featuring a standard 16-pin OBD-II connector, it works with all OBD-II protocols compliant vehicles made in America after 1996 and most modern vehicles made in Europe and Asia. After launching the Mini OBD II app and connecting it to your Bluetooth-enabled iOS or Android device, you can transform your device into a professional-grade automotive scan tool. Free Mini OBD II app is available on the App Store and Google Play Store.

Smart & Real-time Display
With the Mini OBD II app, real-time fuel consumption and other driving information will be displayed and recorded directly on your Bluetooth-enabled devices. Cool HUD (Head-up Display) function enables you to see important information (e.g. vehicle speed) on the front windshield at the eye level, so you can read driving data without looking away from the road, more safe and comfortable.

Intuitive Driving Record
It records driving mileage, fuel consumption, oil costs, average speed, average fuel consumption, time costs and more. It also records and analyzes your driving behaviors and offer suggestions to help you develop good driving habits, minimize damages to your beloved vehicles and save money.

Vehicle Examination
Take a 360 degree full physical examination for your beloved car. Read diagnostic trouble codes (both generic and manufacturer specific DTCs) and display their meanings (database has over 3000 generic code definitions), clear trouble codes, turn off the MIL / Check Engine Light and display current sensor readings and eliminate driving hidden dangers early. Save money by fixing simple problems yourself!

Car Warning
Monitor the whole vehicle status. Real-time alarms can alert you when speed, water temperature or voltage goes beyond normal range to ensure driving safety. You can also set Tired Driving Alert.

Easy to Use
Step 1  Plug the OBD-II Scanner into your car's OBD-II port.
Step 2  Start your vehicle.
Step 3  Launch the Mini OBD II app.

    Very simple and easy to use, connectivity is great! It uses wifi, so the connection never drops, and reconnects when you exit/enter the car. I can scan for codes and also clear them out. Plugged it in and told me the error code of my check engine light. I cleaned it out and the problem went away. I’m so glad I don’t need to go to the garage as they will diagnose my car for free, then sell me low quality, high-profit replacement parts, thank you but I don’t need this anymore. Even I am not a mechanic, knowing the problems that my car's computer sees is valuable. I wonder how much I would have paid the dealer to "solve" my check engine light problem. I just wish I knew about this earlier…..

    L'électronique embarquée est de plus en plus présente dans nos véhicules et nécessite de se doter d'équipements permettant de diagnostiquer les codes défauts, dits DTC, des véhicules. La solution la plus économique est le système OBD2 qui permet de transformer son PC, sa tablette ou son smartphone en outil de diagnostic automobile, permettant de connaître la provenance du problème pour un coût modique. sans vouloir dire de bêtise je crois que le système de broche OBD est obligatoire sur tous les véhicules récents. La mise en place du boitier en lui-même est simplissime. Pour un citroën (Némo, C3) par exemple il suffit d'enlever les deux vis du panneau d'accès aux fusibles, sous le volant pour découvrir la fameuse "prise" OBD en jaune sur la photo. On branche le boitier blanc, une diode rouge s'allume, tout est en ordre ! Il suffit donc par la suite de rechercher l'application mobile "ODB2" sur votre portable, de créer un compte, son profil et surtout en dernière étape de rentrer les caractéristiques du véhicule (marque, modèle, année d'acquisition, kilométrage etc.). Aprè faut un peu de pratique bien entendu. L'application est en anglais et le langage technique pourra paraître trop abscon pour beaucoup. L'idéal est d'avoir un proche qui s'y connaît un peu en mécanique ou électronique, je pense qu'il faut être honnête là-dessus. Je n'ai pas retrouvé mon némo sur la liste de l'application et me suis rabattu sur le C3 d'un proche pour mes essais.

    El dispositivo se envía en una pequeña caja de cartón duro. Debes encontrar donde está el conector en tu coche, normalmente no está a la vista y suele estar situado en algún lugar escondido pero si buscas en google el modelo de coche y OBD seguro que te aparece. Una vez conectado y activado el contacto del coche se puede emparejar a la aplicación, en mi caso la he descargado de la tienda Apple y el emparejamiento es fácil, te preguntará el modelo de coche y a partir de entonces ya puede leer los parámetros del vehículo. Tiene la opción de chequeo para comprobar si hay algún error, a mí ahora mismo me sale todo correcto por lo que no puedo comprobar que aparece cuando hay algún fallo en el vehículo. Me decidí a tener uno de estos dispositivos porque hace poco me ha salido un error y tuve que llevarlo al taller para que le metieran la máquina y lo comprobaran y al final era una tontería que me podía haber evitado. Te dejo unas cuantas fotos del aparato y de la aplicación.

     I was totally expecting a basic OBDII reader that spit out ECM codes for troubleshooting. What I got instead was a fully functioning computer system, that enables live data views, troubleshooting, views of ALL ECM data, and even dashboards that help you become a better driver. I was completely blown away. This is something I'd expect in a $200+ system, not for less than $20. You start by downloading the application (available for Android and iOS). The application name and instructions are provided in the small manual that comes with the reader. Open the application and register with an e-mail and password (required). Once you've downloaded the app to your phone, you turn on bluetooth, and then just go plug in the CACAGOO Bluetooth OBD II Scanner Code Reader onto the OBDII port in your car (driver side, under the dash). You'll need to either select the car type you have from the list, or simply add it to the list as a "custom" car (which I had to do for our Ford Escape Limited). It was very simple to do. Just type it in. Then... open your application, turn on the vehicle, and click connect. That's it. This is where I went from "oh, it'll tell me it has codes" to literally screaming for my son to come check out HOW COOL IS THIS!? The application provides multiple views, everything from dashboards, to ECM data (live stream), and even has a cool HUD feature where you put the phone on the dash in front of you, and you can see your speed and whatnot on the windshield! It blew me away how cool this thing is! I also loved the fact it's got analysis capabilities for determining how safe the driver has been driving (rapid stops, rapid accelerations, etc.), and you can reset the data, too. Botingtom line is that this device will completely blow through any expectations you have (maybe not now that you've read my review). If I could give it six stars, I would. Amazing!

    CACAGOO Bluetooth OBD II Scanner Code Reader Diagnostic Scan Tool Adapter with HUD Display Function for iOS & Android My daughter sent me this so that I could records driving mileage, fuel consumption, oil costs, average speed, average fuel consumption, time costs and more. The product page stated that " Works with all OBD-II protocols compliant vehicles made in America after 1996" so she was hoping it would work with my car. The most important thing this little gadget does is it monitors the whole vehicle status,detect possible problems in time, and finds trouble codes. Real-time alarms can alert you when speed, water temperature or voltage goes beyond normal range to ensure driving safety. I had to replace a water pump because I did not notice the engine was overheating, so this can alert me next time before something bad happens. Note:The vehicle must have a standard 16-pin DLC (Data Link Connector) under the dash and the Vehicle Emission Control Information Label must state that the vehicle is OBD II compliant. Luckily mine did, so I am able to use this. It just plugs into the connector, and you just download the app and sync your phone and you have all the information you need. You can check to see what is wrong if the check engine light comes on, without going to the shop. It is an awesome gadget and I love it.

    I wanted to get one of these little OBD scanner tools but I wanted to get one that also looked nice and work on Android. The other ones I had don't work on android for some reason and only with iPhones but this one works. It is easy to use as well. First thing you need to know is that you have connect to it using your bluetooth not the app. You need to go to the settings of the phone not the setting of the app. Once you connect it using your phone the app should connect automatically. I don't know much else to say other than it works. The app is what really sets it apart so you can use what ever app you want. Over all, I like this thing and I'm happy it worked on my android (Nexus 6p) I have a 2011 Toyota Camry and it works as well.

    I bought the OBD II code reader for my husband as he's into getting all the information he needs from what's going on in his car. The code reader is easy to install, you just plug it in. The app "Mini OBD II" is easily downloaded then when you're in your car it picks up your make and model. Being too eager my husband went through the app in the house before putting in the code reader and couldn't find his car on the list, but it picked it up straight away when in the car. As well as reading codes for faults on your car this little scanner will give you a great amount of information on how your car is performing while you're driving. it gives you your rev counts, your speed, your oil consumption and so much more. My husband is very pleased with it and like every toy he loves to play around with it and check the statistics of all the information collected after every drive. A great little product for a very reasonable price.

    CACAGOO OBD II Scanner Bleutooth Code Reader Diagnostic Scan Tool Adapter with HUD Display Function Free App for iOS & Android Helpful for diagnosing problems and resetting codes :: The Product 1. This white coloured ODB2 code reader is compatible with most modern cars that have an ODB2 port generally found under the dashboard. 2. The dongle is Bluetooth and pairs quickly with Apple and Android phone. 3. This reader can reset codes like a passenger airbag warning light which I got on my VW Passat when I was messing around doing DIY with the centre console. Local garages can charge an excess of £20 to do the 5-second work whereas authorised showrooms will set you back a lot more. 3. There is an accompanying Mini ODB II app which available on both App Store and Play Store. 4. The app shows various readings from your car like Driving Time, Distance, Average Speed, Fuel consumption etc... The interesting aspect is the driving analysis that shows sharp braking and sharp acceleration. :: My Opinion Quality (1..2..3..4..5..6..7..8..9..[10]): 10. Good quality ODB2 reader, easy to plug in and remove. Features (1..2..3..4..5..6..7..8..9..[10]): 10. Compatible with both Apple and Android phones. Overall I am happy with the Bluetooth ODB2 reader and recommend it.

    La norme OBD2 est maintenant très connue et beaucoup d'applications sont disponible sur internet pour récupérer les info de sa voiture. Mais pour ça, il faut une dongle OBD2 compatible. J'ai donc fait beaucoup de recherche et j'ai finalement trouvé la bonne: -petite -bluetooth -compatible J'ai pu faire un reset de plusieurs codes erreur, ce qui m'a fait économiser une sacré somme quand on connait le pris de la valise chez un garagiste. L'application OBD2 est intuitive et il me reste encore beaucoup d'option à découvrir, même si ce n'était pas pour étudier ma conso que j'avais acheter cette dongle, elle s'avère vraiment utile.

    Produit de bonne qualité, fiable aux attentes. Ce scanner se voit être extrêmement utile lorsqu'en voiture quelques informations nous sont demandées et que l'on ne les a pas à portée. Dans le colis, et de manière plus intrinsèque dans la boîte, nous retrouvons le produit lui même et une notice d'utilisation en Anglais (un bon point). Le scanner se voit être très simple d'utilisation, il suffit alors de connecter le produit dans le port prévu à cet effet (OBD-II, facile à trouver). Aucun dysfonctionnement n'as été repéré pour ma part, le produit marche très bien (étant même au dessus de mes attentes). En bref, si vous recherchez un scanner de bord efficace qui saura vous indiquer toutes les informations nécessaires, je vous conseille le produit. Je vous joins quelques photos J'espère que mon commentaire vous aura été utile, si c'est le cas, n'hésitez pas à m'en faire part en cochant la case "OUI" présente ci-dessous. Cela me fait toujours plaisir de me savoir lu et à l'aide des gens.

    # - Le produit : Cette borne ou scanner m'a permis d'analyser les défauts de ma voiture et de pouvoir les effacer, c'est vraiment très simple d'utilisation avec le bluetooth et la bonne application. De plus ce scanner permet d'obtenir des informations sur le moteur, la consommation.. c'est vraiment pratique ! # - Les finitions : Scanner pour voiture classique qui répond aux normes OBD 2. # - Mon avis : Ce produit reste accessible par tous, il n'est pas obligatoire et certain préféreront faire analyser leur voiture dans un garages malgrès le couts important d'une valise chez un garagiste. Quoi qu'il en soit ce produit est très simple d'utilisation et permet pour ma part la résolution de certain problème tel que voyant aide mémoire alumé pour rien etc.. Merci d'avoir pris le temps de lire mon commentaire.

    A few months back I took my 2002 Honda CR-V up to Quebec City from Vermont since the Kia was having work done on it (of course). The car worked fine but the warning light came on and I was kind of worries since it was the dead of winter and there were snow storms and I did not want to break down in the middle of nowhere. Luckily my buddy had one of these gadgets and we plugged it in and realized it was just an old filter that the car needed replaced. I'm not much of a car guy so I don't remember the details but I just remembered that my friend had one of these so I decided to try one. The app works well and it seems like the scanner can detect any issues with the car like it is supposed to. There is a feature in the app to work as a Heads Up Display if your phone/windshield can support it (not a flawless solution but a neat idea - not something I see myself using personally but others might). In general you might be able to save some money by having one of these if you are like me and don't want to drag the car to the shop every time a light comes on

    This OBDII scanner is pretty neat. I had a misfire in my truck a few months back due to a bad spark plug. I took it up to Advance Auto to have them verify that's what it was, even though I was planning on replacing all the plugs anyway. I just didn't want to replace the wires just yet if I didn't have to. That being said, I thought I might purchase this instead of buying a full-on scanner in the event I need it later on. Plus, my wife's Subaru has an ongoing catalytic converter sensor issue that I'd like to verify myself. In terms of ease of use, this is pretty simple and straightforward. I plugged in the scanner, downloaded the app, made an account with just my email, a new password, and vehicle type. It's clear that this is made in China and didn't have any American Ford models (I have a Ranger). Nevertheless, you can input your own model. I think it's just to differentiate vehicles if you're moving it from one to another. There's a HUD option showing MPH and RPM, but it's basically useless. The main thing is the "Engine Health" option. I haven't used it in the Subaru yet to see an actual code, but it did show my Ranger is in "Good Health". I'll update if the Subaru code doesn't work correctly. For the money and ease of use, this is 1000% better than a typical scanner. Plus, you can always leave it in, and pull up the app anytime instead of having to plug/unplug a scanner.

    Great idea! Use it as directed and you can have access to numerous pieces of data about your car's performance. However, it's very important that you know what your doing and you download the correct app. Most importantly, CHECK that using this device will not damage any of the electronics built into your car. I checked with my friendly local Main Dealer before plugging the device into my vehicle. Much of the data you can access will already be available if your car is equiped with an ems/computer that has an in-vehicle display, but it's still a great little piece of 'electronics' and it's excellent value for money.

    This thing is awesome. I plugged it in and downloaded torque pro on android. I started with the free version then after a few minutes I upgraded. all in all I spent some money and I have a scanner that is more capable than the expensive mini scanners and it actually puts them to shame. They have their finer qualities which I appreciate on a really difficult diag but any mechanic that is honest will tell you that 98 percent of diagnostics are simple sensor issues that are pretty obvious to catch. Which means I use this constantly. If you are mechanic, buy this. If you are a shade tree mechanic, buy it. If you like to fiddle with your own cars, buy it. If you even remotely have an inkling of a desire to buy this, BUY IT. Worth the money and a lot of fun. You can create several different screens to monitor different things as well.

    Simple and Effective. I received this product in the post a few days ago and I decided to immediately set it up with my iPhone. Unfortunately, I had a few problems with connecting to my phone but after a few attempts it did seem to work. I downloaded the recommended app, and the product quickly started working and assessing my mother's standard petroleum car. However, when I wanted to test the product on my own hybrid car, it did not work at all. Admittedly, in the description it does say that it will not function with hybrid/electric cars, so I guess that this is my fault. Anyhow, for the money this is a good product and will probably work with your car suitably.

    A great OBDII scanner that works with iOS, this reader is small and compact so it fits in port locations that are less than optimal (mine is by my right leg. With other scanners they've stuck out quite a bit but this one is nice and small so it's not noticeable when plugged in. The app they recommend works fine with iOS and does all the major stuff like reading codes and showing system readouts. Also works with 3rd party apps without issue. I've been looking for an iOS compatible Bluetooth OBDII reader that isn't +$50 and this one is perfect. Highly recommend for anyone looking to read or reset their OBDII codes.
