You're not supposed to press the button. If the self-test works on a '99 vehicle with digital odometer, it'll change the numbers by itself.
It doesn't work on my wife's '04. When I tried, the odo went from miles, to blank, then said "done", and never showed any codes. That needs a DRB scan tool.

I know this works on '98 and older. Don't know about '99. You don't need to touch anything but the key. On a digital odo watch the numbers. With regular gauges, the check eng./ serv. eng. light will flash in a sequence of long then short flashes. Example: 5 long flashes,short pause, 5 short flashes long pause, = 55 End of Message, and so on.
