This system is used only when wheel spinning occurs in a ditch or on a rough surface. This system is effective in case one of the rear wheels is spinning. When the system is normal and the ignition key is turned to "ON", the warning light will come on and will go off after a few seconds. It is not a malfunction that the "VSC TRAC" warning light may stay on for 60 seconds after the ignition key is turned to "ON". 174 2007 4Runner from Aug. '06 Prod. (OM35866U)
