This device can be used to reset the service inspection interval on certain Opel vehicles built after 1998. It simply plugs into the OBD2 port, the user presses a button for the desired inspection interval (15,000km/1yr, 15,000km/2yrs, or 30,000km/2yrs), and the device performs a light show to indicate the reset is complete. The package includes the reset unit and diagnostic connector.
