PSM is your stability management system, so a failure would have to be the failure of one of the wheel speed sensors, which would also affect your ABS brake system, or something in the computer that is monitoring wheel speeds.
Because of everything this system can do, like apply braking to one or more wheel/s, independent of the brake pedal, I would say it is more serious than something you can "get to" when you have the time.
