When a problem arises, the ECU stores a corresponding diagnostic trouble code (DTC). A JDiag OBD2 scanner acts as the bridge between you and your car, allowing you to retrieve and interpret these codes. This empowers you to pinpoint the root cause of issues, potentially saving you time and money at the mechanic.

How Does a JDiag OBD2 Scanner Work?

Here’s a step-by-step breakdown of how a JDiag OBD2 scanner operates:

1. Connect the Scanner: Locate the OBD2 port in your vehicle, usually located under the dashboard on the driver’s side. Plug the JDiag scanner into the port.
2. Turn on the Ignition: Switch your car’s ignition to the “on” position without starting the engine. This powers up the scanner and allows it to establish communication with the ECU.
3. Access the Scanner’s Menu: The scanner’s display will light up, guiding you to the main menu. From here, you can select the desired function, such as “Read Codes.”
4. Retrieve and Interpret Codes: The scanner communicates with the ECU, retrieving any stored DTCs. Once retrieved, the codes will be displayed on the screen, often accompanied by a brief description.
5. Clear the Codes: After addressing the underlying issue, you can use the scanner to clear the stored codes from the ECU’s memory.
