Hi: I have a 1997 CTS. I made a mistake when trying to clear the 50 hour service flag on the monitor. Instead of pushing and holding the engine rpm & the cyl rpm buttons and then turning on the key, I accidentally pushed the ground speed & the cyl rpm and turned on the key. This made the display disappear and the number 1 came up on the display. Now I only have one display instead or 2. Can anyone tell me how to get my display back?

Thanks ......Brent

This in digital tach calibration, to exit pressing the the two right hand buttons, turn the key off this will end the program

Thanks for the reply. Just so I under stand, do I have the key on when I push the two right hand buttons, or do I push the two right hand buttons and then turn the key on and off.

Thanks.......Brent
