X431 support FAQ

Common questions about manuals, registration, and support for this brand.

  • How do I update the diagnostic software on my X431 tool?

    Tap 'Update' on the update page of the Launch App while connected to a strong Wi-Fi network. Select your intended software packages to begin downloading, and they will install automatically once finished.

  • How do I register a new X431 device and app account?

    Open the application, tap 'Login' on the upper right, and select 'New Registration'. Fill in your details, then input the Product S/N and Activation Code (found in the original password envelope) to activate the VCI connector.

  • Where is the VCI connector stored on the X431 V tablet?

    The VCI is typically pre-installed in the docking slot on the top of the display tablet. Press the VCI once to eject it automatically. Always re-insert it when not in use to avoid losing it.

  • How can I connect the X431 VCI to a vehicle without standard OBD II power?

    For non-OBD II vehicles or those with insufficient diagnostic socket power, you can supply power using the included Cigarette Lighter Cable or Battery Clamps Cable connected directly to the vehicle's battery.
