Clearing the codes with a scan tool. If it has been repaired, then the light should go out when the fault no longer exists. If it is a hard fault, the message will come back in a short time after clearing.

Thanks for the input. I have been unable to find some with a code scanner in my area, that will pick up Cadillac codes. It started when it got cold out, it think there may have been some water in the air line and possibly made a blockage. Cause everything seems to be fine.
