That stands for Porsche Stability Management. Make sure there is not a switch to turn the system on and off. If there is not, it will need scanned to determine which sensor is causing an issue.

This light come on and the system is shut down. It will probably be a wheel speed sensor that is out. Here is a guide that will help you read the codes.
Please let us know what you find. I'm interested to see what it is.
Cheers, Ken
