Now, let’s walk through the process of using your Autel OBD2 scanner to diagnose car problems:
-
Locate Your Vehicle’s OBD2 Port: As mentioned earlier, the OBD2 port is typically located under the dashboard on the driver’s side.
-
Turn Off Your Vehicle: Ensure your engine is off and the key is out of the ignition.
-
Connect the Autel OBD2 Scanner: Plug the scanner’s OBD2 connector into your vehicle’s OBD2 port.
-
Turn On the Ignition: Turn the ignition to the “On” position but do not start the engine. This powers up the scanner and establishes communication with your vehicle’s computer.
-
Turn On the Scanner: If your scanner doesn’t automatically power on, turn it on manually.
-
Select the Appropriate Options: Follow the on-screen prompts to select your vehicle’s make, model, and year. This helps the scanner tailor its diagnosis to your specific vehicle.
-
Read Diagnostic Trouble Codes: Select the “Read Codes” option to initiate a scan for any stored DTCs.
-
Interpret the Codes: The scanner will display a list of retrieved DTCs. Each code represents a specific problem area within your vehicle’s system. You can refer to your scanner’s user manual or use online resources to understand the meaning of each code.
-
View Live Data: Most Autel scanners allow you to view live data streams from various sensors in real time. This data can provide valuable insights into the performance of different systems and help pinpoint issues. For instance, if you are curious whether an OBD2 scanner can read your car’s ABS codes, this article can provide insights.

Clear the Codes: Once you’ve addressed the underlying problems, you can use the scanner to clear the DTCs. Keep in mind that clearing the codes doesn’t fix the actual issues; it simply erases the stored codes from the vehicle’s computer.
-
Disconnect the Scanner: After completing the diagnosis and clearing the codes, safely disconnect the scanner from the OBD2 port.
