TRACTION CONTROLY
For Traction Controly warning lights refer to Warning Lights in the
Instrument cluster chapter.
Your vehicle is equipped with a Traction Controly system (except on
commercial conversion packages). This system helps you maintain the
stability and steerability of your vehicle. It is especially useful on slippery
and/or hilly road surfaces. The system operates by detecting and
controlling wheel spin. The system borrows many of the electronic and
mechanical elements already present in the anti-lock braking system
(ABS).
Wheel-speed sensors allow excess rear wheel spin to be detected by the
Traction Controly 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
adjustments are made accordingly.
The Traction Controly 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 Controly 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.
