How to make a personal car diagnostic scan tool with your phone using the Bluetooth adapter ELM 327 and InCarDoc application?

Nowadays, car services are not at the very first place, because a huge number of car problems can be determined through self-diagnostics. 
In order to diagnose the vehicle's onboard computer, or the ECU (electronic control unit), you will need only 3 components:

  • Smartphone
  • InCarDoc application
  • OBD adapter

InCarDoc is a universal, diagnostic application that is very useful driver assistant. With our app, you have the opportunity to get to know better your car inside.

The InCarDoc's main task is to read engine parameters and remove or clean trouble codes (Check engine, MIL). As everyone knows, trouble code Check engine always disturbs a lot of drivers, as the reasons for its appearing there are too much.

How to diagnose a car by yourself?

1. Install the InCarDoc application, which is available to absolutely all users through the App Store and Google Play, you can start working.

2. Connect a smartphone on which the application is preinstalled, to a car with an OBD II diagnostic adapter. 
An adapter plays an important role in the entire process. There are a lot of low-quality adapters in the world market, be careful and get in touch with the original devices. Buy this device only in a trusted store, or consult a car computer diagnostician beforehand.

By connecting the OBD II adapter to the diagnostic socket, which is usually located under the dashboard from the driver's side, and connecting it to the smartphone, you can begin complex vehicle diagnostics.

Attention! To start using the InCarDoc application, the car ignition must be switched on (in position II). 
After connecting the smartphone and the car through the adapter, you can begin the process of diagnostics or scanning of errors on the onboard car computer. No removal instructions are required since this is very easy. 
In less than 10 minutes, all systems will be configured, and errors will have been removed or corrected.
