Connect your smartphone with your Universal Carly adapter through the Carly App to find out what works for your unique car.

Carly can read out and clear fault codes that other scanners cannot. Carly reads from all built-in electronic control units (ECUs), including Engine, Transmission, ABS, Airbag, Multimedia, and more. In addition to reading the codes, Carly interprets the severity of the issues and saves your car's health history.
It’s important to catch potential problems before they cost you dearly - for example, engine-related issues can cost up to $10,000. Mechanics recommend running diagnostic sessions several times a year, but each session can easily cost you over $60.

Those who reduce car mileage can sell the vehicle for almost $5,000 more than the actual value. Carly sources KM/Mileage/Lifetime data and VIN from different ECUs (control units) of your car to detect cases of manipulation and tampering.
With the Used Car Check feature you’ll know if the car mileage was manipulated and more.
This is a Beta feature. To check, if the feature could be supported for your model, go here. It as well depends on the build year and the built-in hardware of your individual car.

Carly reads out and monitors detailed engine data, such as temperature and pressure values.
Live parameters or live data can help you take the guesswork out of understanding what your car needs or detect the fault origins.
Works with all car brands.

Use the app to test emission relevant systems and procedures for exhaust systems of your car.
Catch emission issues yourself, before you get your car serviced and talk to your mechanic at eye-level.

With the OBD functions, read and delete all OBD engine fault codes and perform maintenance work with detailed data (e.g. oil temperature, rpm), or test emission relevant systems and procedures for exhaust systems.

All of your past reports will be saved on your smartphone so you can refer back to them whenever and wherever you’d like. You can then generate official Carly PDFs and email them. The reports depend on the features that are available for your car.
Your Digital Garage provides a place to store diagnostic reports, used car check reports, and coding backups. It makes it easy to share it with your mechanic or potential car buyers.

Cars have hidden internal settings that the average consumer doesn’t have access to. With Carly it is simple to adjust the code of your car so you can customize your car, exactly to your liking. Don’t like what you did? There is an automatic backup feature that easily allows you to return to the original settings.
Customize your car to your liking by making adjustments through Carly’s coding feature. Examples include adjusting the look of your interior lights, change how your windows work, and so much more!
This is a Beta feature. The coding feature is supported for the majority of Toyota and Lexus cars with the build year starting from 2010. To check if coding works for your car go here. Check what are possible codings for your Toyota model here or your Lexus model here.
What you can do with Carly varies from car to car. Get your adapter and find out what could work for yours.
