Find out why your "Check Engine" light is on: Carista shows you a list of the fault codes stored in your vehicle, as well as their meanings. You can also reset the "Check Engine" light.


Dealer-level electronic diagnostics (fault code checking and resetting) of all modules in the vehicle, incl. ABS, airbag, and other manufacturer-specific systems.


Personalization of comfort & convenience features of the car. Customize your car to your liking and get rid of all those annoyances you have to deal with every time you get into your car. You can even enable hidden features that you didn't even know your car had!

Carista shows you if your car is ready for Emission tests -- that way you can avoid the trip to the testing station before the vehicle's systems have gathered enough driving data to be ready for testing.
