How to Use DiagBox

To use DiagBox, you will need the following:

  • A Windows PC with DiagBox software installed

  • A Lexia 3 interface connected to your PC via USB cable

  • A Peugeot or Citroen vehicle with OBD2 port

Follow these steps to use DiagBox:

  • Connect your Lexia 3 interface to your vehicle's OBD2 port using the OBD2 cable. The OBD2 port is usually located under the dashboard on the driver's side.

  • Turn on the ignition of your vehicle, but do not start the engine.

  • Run the DiagBox software on your PC as administrator.

  • Select your vehicle's make, model, year, and engine type from the drop-down menus.

  • Select the function you want to perform from the menu on the left side of the screen. For example, you can select "Faults" to read and clear fault codes, or "Global Test" to perform a comprehensive scan of all systems.

  • When you are done, exit the DiagBox software and disconnect your Lexia 3 interface from your vehicle and PC.

Tips and Troubleshooting

Here are some tips and troubleshooting steps to help you use DiagBox more effectively:

  • Make sure your PC meets the minimum requirements for running DiagBox software. You can check them in [the installation guide].

  • Make sure your internet connection is stable during the installation and activation of DiagBox software. If you lose connection, you may need to restart the process.

  • Make sure your Lexia 3 interface is genuine and compatible with DiagBox software. Some cheap clones may not work properly or cause damage to your vehicle or PC.

  • Make sure your Lexia 3 interface is connected securely to your PC and vehicle. Check if the cables are in good condition and not loose or damaged.

  • Make sure your vehicle's battery is fully charged and the ignition is on. If the battery is low or the ignition is off, the communication between the Lexia 3 interface and the vehicle may be interrupted or corrupted.

  • Make sure you select the correct vehicle information in the DiagBox software. If you select the wrong make, model, year, or engine type, the DiagBox software may not be able to communicate with your vehicle or perform the desired function.
