Decision guide

Identify the device first in Xdiag Pro 3 searches

Installation steps should not be chosen without seeing the device's full name, connection interface, application screen, serial number or device ID, and current license information.

The name Xdiag may appear in different contexts with applications, licenses, or device packages. When purchasing and registering for support, the current hardware model, serial number, application name, and license screen must be specified separately.

For used or long-unused devices, account access, license duration, and region information can change the outcome. Even if the device powers on, current brand packages or target service menus may not appear.

Decision guide

How are installation and activation distinguished?

Installation is the loading of the application onto the device; activation is making the license functional with the device and account. These two steps should not be considered the same outcome.

If the application opens but does not connect to the vehicle, the problem could be the VCI, Bluetooth, cable, ignition position, or device matching. Brand packages or operation menus may also not appear as expected until activation is complete.

To isolate the issue, first check if the application opens, then the activation status, and finally the VCI connection. The error screen, device ID, and license duration should be included with support requests.

Decision guide

Vehicle Coverage and Service Operation

Xdiag Pro 3 vehicle coverage is determined from the manufacturer's records of make, model, year, engine or system, control unit, and the operation to be performed.

Reading codes, live data, service resets, active tests, or special functions do not have the same expectations. The software showing the vehicle brand in the list does not mean all operation menus will be available for that vehicle.

The actual SKU, compatible devices, license delivery method, duration, price, support, and digital product return conditions must be clearly stated in the Xdiag Pro 3 listing. Payment should not be made if this information is missing.
