About this app

See what your car is doing in realtime, get OBD fault codes, car performance, sensor data and more!
Car Scanner is a vehicle / car performance / trip computer / diagnostics tool and scanner that uses an OBD II Wi-Fi or Bluetooth adapter to connect to your OBD2 engine management / ECU.
Car Scanner gives you a bunch of unique features:
1) Layout your own dashboard with the gauges and charts you want!
2) Add custom (extended PIDs) and get information, that was hidden from you by car manufacturer!
3) It can also show and reset a DTC fault code like a scantool. Car Scanner includes a huge database of DTC codes descriptions.
4) Car Scanner allows you to read free-frames (sensors state when DTC is saved).
5) Now with Mode 06 - you can get ECU self-monitoring test results. Helps you fix your car and helps keep repair costs down!
6) Check if your car is ready for emission tests.
7) Check all of the sensors at one screen
8) Car Scanner works with any vehicle that uses the OBD 2 standard (most vehicles built after 2000, but can work for vehicles as far back as 1996, check carscanner.info for more details).
9) Car Scanner includes a lot of connection profiles, that gives you some extra features for Toyota, Mitsubishi, GM, Opel, Vauxhal, Chevrolet, Nissan, Infinity, Renault, Hyundai, Kia, Mazda, Ford, Subaru, Dacia, Volkswagen, Skoda, Seat, Audi and others.

- Some of Renault/Dacia (compatibility may depend on your car modules and firmware versions);
- Several service functions available for other cars.
14) And one more thing - Car Scanner provides the widest variety of features for FREE across the Play Market.

The app requires a Wi-Fi or Bluetooth or Bluetooth 4.0 (Bluetooth LE) OBD2 ELM327 compatible adapter (device) to work. ELM327 devices plugs into the diagnostics socket in the car and gives your phone access to car diagnostics.
Recommended adapters brands: OBDLink, Kiwi 3, V-Gate, Carista, LELink, Veepeak.
If you buy one of the cheap china OBD2 ELM327 adapters from ebay / amazon, then make sure it’s not marked as v.2.1. This adapters are supported, but they have lot’s of bugs.

PLEASE NOTE: Vehicle ECUs vary in the amount of sensors supported. This app can’t show you something, that is not provided by your car.

Attention "bad" adapters! We faced the problem, that some adapters (often cheep Chinese clones), can’t connect to the smartphone or the car. Some of them can even make your car engine work unstable, often lost connection, increase time lag when reading data.
So, we recommend you to use genuine ELM327 or recommended adapter brands.

I have used CarScanner a few times with my IONIQ 5. Today, suddenly, the gauge I wanted to read says only available in the pro version. I looked around in the app and on the website and wasn't able to find any explanation as to why this behavior started suddenly in the middle of my road trip. I ended up buying it. It's really frustrating to buy something without understanding what I'm getting. I wish the free and paid features were enumerated so that I wasn't surprised in the middle of my trip.

Fantastic app, used in conjunction with a Veepeak OBD Check Plus something something. I'm super impressed with how in depth it is. So much more than a code scanner. Data logging? Check. Live sensor readouts? Check. Virtual dashboard that can even go into HUD mode? Check. There's so much more to it, and for what it is, this is truly an incredible deal for what it costs. Buy the full version. You won't regret it.

This app seems to have more features available in the free version than most other free OBD2 readers. The interface is also easier to use than others I've tried. I'm not sure I'll ever need the paid features and the ads are completely unobtrusive. I paid for the upgrade just to thank the developer for an amazing app.
