Car Scanner is a vehicle / car performance / trip computer / diagnostics tool and scanner that uses an OBD II Wi-Fi or Bluetooth 4.0 (Bluetooth LE) 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!

3) It can also show and reset a DTC fault code like a scantool. Car Scanner includes a huge database of DTC codes descriptions.

The app requires a Wi-Fi or or Bluetooth 4.0 (Bluetooth LE) OBD2 ELM327 compatible adapter (device) to work. ELM327 devices plugs into the diagnostics socket in the car ang gives your phone access to car diagnostics.
Recommended adapters brands: Kiwi 3, Viecar, 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.

Moonie 5987 on

Just started using but so far it’s great. I like the easy connecting. And so far I like everything else about it.

Just what it is supposed to be.

The quality software and $6 lifetime no ad is the easiest purchased decision in a long time.

Works GREAT!

Bruce RB on

I wrestled which way to go about installing a temp gauge in my Mini or go OBD2 route. I’m so glad I went this route for iPhones. After following the OBD Bluetooth suggestions and installation instructions, it works just as I wanted and then some. I’m a auto technician and use if primarily for the coolant temperature, but also created other screens to monitor different systems Well done! 💪😃

2023 Toyota Hybrid

When will Toyota 4th gen Sienna be added?

Incredible

Jondoe2003 on

I downloaded a ton of free OBD2 readers, and this one takes the cake. I use it to monitor hybrid parameters on my Fusion like state of charge and current, as well as temps and MPG. I also bought a ScanGauge 3 but will be returning it and saving a ton of cash. The app graphics are a bit primitive, but this is made up for by a ton of customization options. Several data display types and you can set colors, visual, and auditory alerts. I bought it just to have the extra screen space where the ads were. It seems like you can do everything without buying anything.

К айфон не подключается

Your quality system has helped put my mind at ease, being able to easily determine what I need to give attention to on our families vehicles, being able to reset and reassess codes and there recurrences has really been a blessing, to me, over & over 🙂! Thank You from Paul in Holland, Michigan

Great scan tool app

Hunter45641 on

I payed 10.99 for the adapter and I use this app for free! Definitely saves me time and money from having to stop at a parts store for a quick diagnostic scan.
