klavkarr - The OBD2 car diagnostics scanners 100% made in France

To choose your diagnostic tool, it is important first to determine whether you want a device compatible with all market brands or only a specific manufacturer. We also recommend choosing a diagnostic tool paired with software in French. This will simplify code reading and overall use of the interface for recording, editing, or modifying reports. Finally, it is important to choose a quality device that is aesthetically pleasing and easy to handle, especially if you plan to use it regularly, perhaps even daily.

A diagnostic scanner comes in the form of a universal device that adapts to the vehicle, regardless of its brand and model. You need to connect this device to the OBD port. Where is it? That depends on the brand and models. To assist you, we offer an application that helps identify the location on each car. Convenient!

In addition to the device, such as the ELM327, which must be connected to the vehicle, you need software for diagnostics.

The klavkarr diagnostic tool that you connect to the OBD2 port of your car already integrates the EOBD Facile auto diagnostic software. The klavkarr can be used on both your smartphone and a computer.

When the diagnostic tool is connected to the OBD port, it can start collecting data from the ECU. Next, you need to read this data. Through a dedicated application that connects to the device, you can read and clear fault codes. These codes always have the same format: a letter followed by a series of four digits. Most of the time, you will encounter faults that start with the letter P, meaning "Powertrain," indicating a fault in an engine or gearbox component. However, you may also encounter codes starting with C (chassis), B (Body, meaning the interior), or U (User Network, for faults related to electrical or electronic systems). All these codes are standardized, but some are specific to manufacturers. To identify them, you can refer to technical manuals or a list of error codes.
