Carista is a smartphone application for both iOS and Android devices that allows owners to diagnose vehicle faults, reset service indicators, and customize vehicle systems without any complicated coding. 

In order to use Carista on your vehicle, only three things are required:

• An iPhone, iPad, or iPod touch running iOS 8.0 or later OR an Android device running Android 2.3 and up
• The Carista OBD2 App: Available on the Apple AppStore and Google Play
• Bluetooth OBD2 Adapter: Available HERE!
  • Uses Bluetooth 4LE which prevents drainage to the car's battery due to it's power saving mode.
  • Since the adapter is Bluetooth, the Wi-Fi connection on your mobile device remains open so you can still browse the internet while still remaining connected to the vehicle. 
  • The Carista Bluetooth OBD2 Adapter is also compatible with the OBD Fusion app on iOS and Android.

Diagnose (OBD2):
Carista can check your vehicle's health and report any faults stored in its computers. You can also clear any fault codes and reset your "check engine" light, as emissions test readiness. This is a FREE feature.

Diagnose (Manufacturer-Specific):
Unlike regular OBD2 apps, Carista also gives you access to advanced manufacturer-specific diagnostics, including computers like ABS, airbag, navigation, etc. and gives you the ability to reset your airbag light, ABS light, traction control light, etc. Manufacturer-Specific Diagnosis is a PAID feature; supported vehicles only.

Customization:
Carista gives you the power to personalize the behavior of your car’s windows, lights, instruments and more, with a click of a button. Customization is a PAID feature; supported vehicles only.

Service:
With Carista’s DIY tools, resetting your oil service indicator, servicing your electronic parking brake or checking your launch control count becomes a 1-click action. This is a PAID feature; supported vehicles only.

Pricing:
All PAID features listed above are available with an in-app purchase of Pro functionality: complimentary 1 month trial included, annual subscriptions are $39.99/year.
