Step 3: After the obd2 scanner boots up successfully, it would prompt the user to input some answers to the questions. You need to enter all the details as requested, this could include the car model, engine type, etc.

Step 4: After you enter all the details as requested, you need to wait for the obd2 to process the details and to analyze and scan the diagnostic system of your car. If the process does not start automatically, you should press the start button, if you can’t find the button, then check the user manual for more information.

Step 5: Once, the scanning is completed, the obd2 scanner would display some codes on the screen, if the process was not successful, an error message would be displayed. No matter what, you need to note down the codes displayed on the screen.

Step 6: Now, you need to pick up the scanner manual that came with the obd2 scanner. Remember, every obd2 scanner will have a manual and this manual would have the codes and their details.
