This device is designed to connect the car interface with the computer interface and convert the streaming signals that go along the K- and L-lines to the USB format. You can buy this device in any auto parts store for a fairly reasonable price. In the event that it is possible to make a K-Line adapter with your own hands, first of all you need to purchase accessories and have a reliable information base.
The operation of an electronic device significantly reduces the risk of potential damage to car systems and timely informs the driver about it. In this article we will talk about using the K-Line adapter, as well as how to make it yourself.
Main application
The KL-Line adapter is used for diagnostic work and determining the operating parameters of engines on foreign cars, as well as domestic cars that are equipped with electronic control units for engine systems.
After connecting the adapter and running the appropriate program on the computer, the following diagnostic operations can be performed:- Carry out in-depth diagnostics of engine systems.
- Detect and read trouble codes.
- Use the full range of service functions (drying spark plugs, engine warm-up).
It is also possible to carry out control and monitoring of systems during movement:
- Current voltage in the car's on-board network.
- Engine speed and temperature.
- Fuel consumption control.
- Speed indicators.
- The current state of various sensors and the causes of their malfunction.
- Movement time.
- Kilometer traveled by vehicle.
Software
Diagnostics with a K-line adapter is possible only with special software that will match the brand of the car.
Diagnostic measures on domestic GAZ and VAZ cars are often carried out using the Open Diag program (1.3.9). It is the latest version, perfect for VAZ, UAZ, GAZ car models.
Also, for the diagnosis of VAZ models, the Motor-Tester and Diagnostic Tool v 1.3.1 programs are used.
Motors equipped with an electronic fuel injection control system with IKAS-5.4 control and their modifications, as a rule, GAZ and UAZ, are diagnosed by the adapter using GAZ-DIAGN software., . , . , Chevrolet " " v 1.6. K-Line , , . "".

Cars manufacturer VAG (Volkswagen, Seat, Audi, Skoda including) with an electronic fuel injection system work with the program VAG Com. K-line adapter reads and processes the information of all engine components, which allows to prevent and eliminate various malfunctions in a timely manner.
Diagnostic tool "Motor-Tester" is widely used for diagnostic operations of domestic transport systems.
It is not whimsical and can be used in almost different conditions. Through the K-Line adapter, the software takes readings from the electronic control unit. At the same time, it is possible to save indicators that the tool visualizes both in digital equivalent and in graphical form.
Uniscan is a program that has established itself as being more universal. It can be used on vehicles manufactured in the United States, Asia and Europe with a year of manufacture up to and including 2001. By downloading this program to a computer, you can easily carry out diagnostic operations of machine systems and determine with high accuracy the cause of a malfunction of a particular part.
How to make a K-line adapter yourself
This tool can be made with your own hands. A simpler circuit is on Com, but due to the lack of this connector on laptops, it is less practical and therefore unpopular.
As for the schemes with the ability to connect via USB, this is not the case here. They are more practical, but have a complex design. To facilitate this task, craftsmen began to use a data cable from unusable mobile phones.:

First, load the K-Line driver of the PL2303 adapter with the ability to support non-standard speed. After the driver is installed, you must connect the cable and make sure that it is working. In this case, it will appear in the device manager on the computer display. Next, you need to remember under what value it is attached. To check the port, you must install the B&B Com Test.Data cable: connection and conversion

Then we connect it to the two remaining ones, and when connected to the correct wire in the program window, previously entered information will be copied. This is the output of RxD. Once the values are set, they should be soldered according to the diagram.Before turning on the K-Line adapter, it is important to make sure that the device is installed correctly and that there are no short circuits in the circuit and wires.
Health Check
Check the device’s performance as follows.
We connect the adapter to the computer port (after supplying it with 12 watts) and use the same program to check it. If the information entered in the upper window is duplicated, then the device is working and it can be connected to the electronic control unit of the car.Hidden device features
