I was thinking he might mean automatic temperature control?

Default ATC FLASHING

THE ATC DISPLAY THAT IS FLASHING IS THE AUTOMATIC TEMPERATURE CONTROL.

I COULD ONLY LOCATE A DIAGNOSTIC PROCEDURE FOR UP TO 1993 BONNEVILLE.

I HAVE READ SOME REFERENCE THAT A DEALER SCAN TOOL IS NEEDED TO DIAGNOSE AFTER 1993. IS THIS CORRECT?

97-SSE, I believe that there is a thread somewhere here that discusses how to reset the ECC (ATC) after an electrical issue. If you don't find it in the next hour, I will look it up after lunch, as I have to run right now.

You may not need diagnostics is what I'm saying.

I COULD NOT FIND THE 97 ECC (ATC) RESET PROCEDURE.

YOUR HELP IN LOCATING IT WOULD BE APPRECIATED.

Please turn your caps off. Thank you.

Try searching on ECC as we refer to it as an Electronic Climate Control. However there isn't a known way after 93 to read it w/o the dealer scan tool.
