How it works

Understand Health Diagnostics

Diagnostic fault codes (DTC’s, also called trouble or error codes) identify a particular problem area outside the normal range and show where a fault might be occurring (i.e. fuel mixture too rich) even when the warning light is not showing it.

BMW 3 Series

The modern vehicle contains data from up to 80 complex electronic control units. Carly reads out the data, interprets it and visualizes for you in an easy and understandable way.

Most Common Questions

Why should I make regular diagnostics?
Arrow down
The faults can appear even before the engine or other warning lights turn on. These minor issues can turn into bigger problems in the course of days or weeks, and when the warning light is on, it can already be too late or very costly.
Which electronic control units does the Health feature cover?
Arrow down
This depands on your car brand. Brands as BMW, Mini, Audi, Skoda, Volkswagen, Seat, Toyota, Lexus, Mercedes, Renault and Porsche have been in development for a long time and have more functions available, such as manufacturer-level diagnosis on systems like, Engine, Transmission, Emissions, ABS, Airbag, Multimedia, and more. Other brands were implemented recently and we offer the OBD functions (OBD diagnosis and OBD parameters) for the time being, which covers the most critical systems like Engine, Transmission and Emissions.
