About this app

Mobile direction of the OpenDiag project!

Software for Android 3.1 and higher for diagnosing Russian-made domestic cars using ECU protocols, using ELM 327 Bluetooth or Wi-Fi adapters, USB ELM 327 or K-Line, USB K+CAN Commander v1.4.

Ability to work with files on computers and Android devices is a MUST!

ELM The program is focused on original ELM327 chips https:// www.elmelectronics.com. Not all Chinese adapters support the full functionality of the original ELM327. Therefore, if OpenDiag does not connect to the ECU, there is no need to “kick” it with other programs that connect. They communicate with the ECU using the OBD-II standard. OpenDiag communicates via the ECU protocol and requires the full functionality of the original ELM327. The OBD-II standard is supported by the program in its simplest form, select the OBD-II unit and connect!
USB USB adapters require USB-Host support on your smartphone or tablet.
Supported USB adapter chips (tested): FTDI (FT232RL), WCH (CH340), Prolific (PL2303), Silicon Labs (CP2102, speed override required https://chiptuner.ru/content/pub_20/).

Do not install the program on devices with this firmware, otherwise the device will go into an eternal reboot!

Attention!
* Automatic detection of your car's ECU is NOT GUARANTEED!
* There are no diesel units in the program.
* The program contains blocks with paid content. When connecting to such a block, the program tells you what is needed to activate the block, or how to disable the demo mode of the block.
* Activating the block does not solve problems with connecting to the ECU!
* Owners of activated blocks on one device can activate these blocks for two more devices for free.
* Changing the device is free.
