Read the trouble code by following the method in post #2 in this thread: http://www.rav4world.com/forums/99-...forums/99-4-3-mechanical/85765-check-engine-light-vsc-4wd-lights-explained.html

Cross reference the blink code with the chart on page 3 of this PDF: http://www.moranbahweather.com/toyota/70series/lc_70e/ncf/ncf258e/m_10_0513.pdf

That should give you an idea of where to start looking, at least.
