Wheel-speed sensors allow excess
rear wheel spin to be detected by
the Traction Control
y
portion of
the ABS computer. Any excessive
wheel spin is controlled by
automatically applying and
releasing the rear brakes in
conjunction with engine torque
reductions. Engine torque
reduction is realized via the fully
electronic spark and fuel injection
systems. This process is very
sensitive to driving conditions and
very fast acting. The rear wheels
“search” for optimum traction
several times a second and
adjustment are made accordingly.
The Traction Control
y
system will
allow your vehicle to make better
use of available traction on
slippery surfaces. The system is a
driver aid which makes your
vehicle easier to handle primarily
on snow and ice covered roads.
During Traction Control
y
operation you may hear an electric
motor type of sound coming from
the engine compartment and the
engine will not “rev-up” when you
push further on the accelerator.
This is normal system behavior.
If you should become stuck in
snow or ice or on a very slippery
road surface, tyro switching the
Traction Control
y
system off. This
may allow excess wheel spin to
“dig” the vehicle out a enable a
successful “rocking” maneuver.
If the Traction Control
y
system is
cycled excessively, the brake
