I had that combination of lights on a 2010 Vibe, and it turned out to be a rear wheel sensor and harness. VSC Off was flashing, and the ABS, Traction, and Brake lights were on steady. I took it to Advance and their reader happened to read ABS codes--codes were C1403, C1422, C1407.
I didn't have the time or place to fix it myself that February, so I had it done when it was at the dealer for a recall. The tech said the harness had shorted and it took out the sensor. On the Vibe, Toyota/GM were kind enough to design it so the entire hub needs to be replaced rather than just the sensor. To go along with earlier comments, the codes will help you figure out what to fix or know what to expect if you take it somewhere.
