Can someone please tell me how to enter diagnostics on the information panel on a 1999 Seville STS? Also do the same codes for a 1995 STS pertain to the 1999 STS?

The codes will be different I believe because 95 may still be OBDI while 96 and up are OBDII. On my old 89 I just simultaniously push and hold Off and Warmer to enter the self diagnostics, it's similar with the newer ones but I think there is a slight difference.

Someone will be along shortly to give you the proper buttons to push.

Press and hold the On/Off and Info Up buttons at the same time until all the dash lights go on. It will then display "All?". Press the On/Off button and it will say "All Codes?". Press the On/Off button once more and it will begin to read off the codes. Get a pen or pencil ready. If you miss any, you can always use the info button to scroll back through the menu and read the codes off again, using the On/Off button to select each option.

Sure, no problem. If your curious as to what any of the codes mean, just post them here, and we'll tell you what they mean. Good Luck.
