i know this works with an 02 you can try this trick and see if it works for you.

To enter the HEC Dealer test mode, Depress and hold the instrument cluster SELECT/RESET button,
Turn the ignition switch to the RUN position
Continue pressing the SELECT/RESET button (5 seconds) until tESt is displayed in the odometer.
Note: SELECT/RESET button must be released within 3 seconds of the odometer tESt display to begin the dealer test mode.
What will happen next is all your analog needles will "sweep" to their max positions and then drop back to normal. The digital readout will say "GAGE".
Push the button once and the next diagnostic will display

I'm glad you posted it. I wanna try it tonight but my car is in the shop til tomorrow night . I'll try it on my friends 2000 GT and let you know if it works on a 2000.

Also do you have to do it everytime you start the car in order to get it or does it stay on there?
