The device is an OBD II (EOBD) fault diagnosis device that is suitable for reading out and deleting engine control fault codes on vehicles with an OBD II interface. It does not support the diagnosis of comfort or safety systems such as airbags or ABS.

For the Fiat Ducato 8 (Camper Van), it should be noted that it generally has an OBD II interface if it is a model built from 2001 onwards, as OBD II is mandatory in Europe from 2001 for petrol engines and from 2004 for diesel engines. The device can therefore generally be used for the engine control unit of the Fiat Ducato 8, provided the vehicle is OBD II-compliant. There is no specific manufacturer information on compatibility with the Fiat Ducato 8, but the OBD II interface is standardised and the device reads out all OBD II error codes in plain text.
