Very simple to use! You don't even have to select your car model. Just enter your fault code and app will show you all supported descriptions. No Internet connection needed, no longer spend hours to search for single code description, looking at check engine light.

If you have usb, bluetooth or WiFi OBDII code reader (ELM327, PLX Kiwi or any other) you need this app for code description because most of code scanners does not contain full DTC (diagnostic trouble code)  database and displays only meaningfull numbers.
