Not Supported By PCM?

I was checking to see if I had any codes and getting this: PROM ID NOT SUPPORTED BY PCM

What would cause this and can/will it cause problems?

I have no clue, the car was bought used.
With the prom ID not supported, would it cause any issues?

Possibly, with gm scanner you maybe able to get around it. Using onboard there is a good chance it will be a problem.
