The computer for the ABS computers gave problems on these gave a bit of problems. Any fault in the park brake system, or brake system will bring on the Vehicle Stability Control System light (VSC). But have the system checked out before jumping to conclusions or condemning the ECU.
I had the same problem on my 2007 Sequoia to find that the brake fluid was low due to excessive wear in the rear brakes. I don't yet have a good answer why the rear brakes would be worn almost to the metal in less than 43K miles of highway driving.
