If this doesn't work on your Corrado VR6, try the same with the trip/odometer reset button. That's known to work on some SLC's..

If the results are odd, and your driving computer doesn't work, it can be reseted just by disconnecting the battery.

Oh, and you can also get to the measuring mode test by setting the mode memory switch to position 2 instead or 1.
