The system has detected a leak in the evaporative system and it wants you to check your gas cap since that is the most common reason for an evaporative system leak. If the cap is ok then more than likely you have a leak that is not contributed to the fuel cap. The computer has no way to physically check the fuel cap, it can only assume the possibility that you may have left it off.
