UDIAG support FAQ

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

  • How do I update my UDIAG scanner?

    Download the UDIAG updater tool from the official website. Connect your scanner to a computer via USB, hold the Help key (if applicable), and follow the on-screen prompts in the updater software to select and install the latest software version.

  • How do I power on the UDIAG code reader?

    The device is typically powered directly through the vehicle's OBDII port. Connect the scanner to the Data Link Connector (DLC) and turn the ignition key to the ON position; the unit should boot up automatically.

  • What should I do if the scanner fails to communicate with the vehicle?

    Ensure the vehicle ignition is in the ON position. Check that the OBDII connector is securely attached to the vehicle's DLC. Inspect the DLC for any debris or damaged pins.

  • Does the warranty cover accidental damage?

    No, the standard UDIAG warranty covers hardware defects for one year but does not cover damage caused by human factors, accidents, or misuse of the product.

  • Where can I find the OBDII port on my car?

    The Data Link Connector (DLC) is usually located under the dashboard on the driver's side, often within 12 inches of the center of the instrument panel.
