There are quite a few things that can cause this light to turn on and yes you are right it has something to do with the hybrid system, unfortunately this going to require that a suitable diagnostic scantool be connected that can communicate with all the onboard computers, this will retrieve any diagnostic codes that are stored, a technician can then start to diagnose the system based on the trouble code information.

SOURCE: what is a vsc warning light on a toyota estima
It stands for Vehicle Stability Control When the VSC system takes control it activiates stability correction. The slip
indication light flashes while the buzzer activates. The VSC is able to operate
at all times except when the centre differential is locked. When the centre
differential locks, the VSC-OFF light in the combination meter illuminates to
inform the driver that the VSC function has been turned OFF. The centre
differential lock is designed for freeing the vehicle if it is stuck in mud for
example, however it would be difficult for the vehicle to free itself if the
engine output were reduced due to the operation of VSC. Therefore when the
centre differential is locked, the VSC function is turned OFF.If a malfunction occurs in the VSC system, the VSC warning
light illuminates to alert the driver.
If the vehicle with VSC begins to oversteer or understeer because
of an emergency avoidance measure, or by excessive speed in a corner, VSC will
automatically activate. By adjusting the engine’s power output and braking each
wheel independently, VSC helps to return the vehicle to a ‘zone of stable
operation’..
