Diag device to automotive computer
Using a diag device is literally as simple as plugging in a regular device and turning it on. The main issue is that you need to find the right port and know how to operate the device.
For this, you need to find the OBD2 input of your car; This entrance is usually located somewhere near the steering box or under it. Of course, this port is on the passenger side or somewhere around the central console in some models. It is better to check the car manual to find the exact location and to know more. Be sure to turn off the car before connecting the car scan tool to the OBD2 output.
Generally, the diagnostic tools download data from the diagnostic port (OBD2) inside the car. This port, which is standard on all cars produced in the world market, allows you to access almost any error detected by the central computer. You need to manipulate the settings a bit to access the information.
After connecting the end connectors of the diagnostic device to the OBD2 port, make sure that the connection is stable and tight. Only in this case, the diagnostic device can communicate with the car's ECU.
Turn on the car. Of course, if your car's engine stores the vehicle codes, you don't need to do this. Usually, in order for the central computer to control the health of the engine properly, you have to start and keep the engine running until the end of the work.
Download the codes
The golden key to the troubleshooting process is the specific codes that your car displays during troubleshooting. A diagnostic tool can download these codes, read them, and in this way, diagnose things that are faulty or not working properly.
Reading codes
To understand all the codes, you need a code reader to translate each error code into simple and understandable words. Professional diagnostic tools provide you with an explanation of each error code on the device screen.

Keep in mind that the codes do not necessarily mean that there is a problem in the same part, and sometimes the root of the problem is somewhere else. This point can only be obtained with skill and experience. The next thing is that diagnostic devices are not always the right thing to solve the problem, and to solve the problem in a better way, more and more equipped devices are needed (such as a programmer or tester).
