e Stabilit y Assis t (VSA ) Syste m
The Vehicle Stability Assist system (VSA) monitors the car's actions
during straight-line acceleration and
cornering behavior. It reduces
engine power and applies selective
braking if it senses any loss of
traction.

Straight-lin e Acceleratio n
If one drive wheel is turning faster
than the other, or both drive wheels
are turning faster than the non- driven wheels, VSA senses
wheelspin. It reduces engine power and applies braking at the wheels as
necessary to increase traction.
To do this, VSA monitors the pulse frequencies from the wheel speed sensors. It also uses information
from the steering wheel angle sensor
and the lateral acceleration sensor to determine if the car is accelerating in
a straight line or if it is cornering.
VSA can then calculate how much wheelspin, if any, to allow. It signals
the ECU to reduce fuel flow andretard ignition timing. This reduces
available engine power. The ECU
will also apply braking at the wheels as necessary. When wheelspin has
been controlled, braking and engine
control return to normal.

VSA monitors steering input and the car's expected response to that input.
VSA's yaw rate sensor measures the car's actual cornering behavior. If VSA determines that the car is
turning more or less than expected,
the system reduces engine power
and applies braking at the
appropriate wheel to try and
maintain adequate traction during
cornering.
VSA uses the same wheel speed sensor assemblies as the ABS.
Additional sensors measure steering wheel angle, lateral acceleration, and
yaw rate.
The control unit monitors the VSA circuitry while driving. If it senses a
problem, it turns off the system and illuminates the VSA System
Indicator on the instrument panel.
