Check your switches for the VSC, some get bumped on (due to their location) and some get stuck in the "on"position.

Look up above your brake pedal and you should see a switch that is connected to it. This switch controls your brakes and in some vehicles, is tied in to the safety system. Change this and see if your van goes into gear ($10 part)

Krafty930 with brake, VSC off and ABS lights on. You share a common problem with many Toyota owners. My 2003 Sequioa has the same issue. There is no solution. Dealers will replace the air sensors and then the computer all for $2,500 - $3,500. This will not solve the issue. The internet has thousands of complaints re this problem, but Toyota has disowned the issue and declined resolution, even for vehicles under warranty. The lights drive me crazy and I still don't know if there is a functional problem, a wiring problem or a computer problem with the VSC system. To date, I have learned of no reports relating this problem to vehicular deaths, so I really am not holding my breath waiting for Toyota to provide a solution. Sorry that you share this problem, but perhaps my response will help to stop you from "spinning your wheels" too much trying to resolve this issue.
