Traction Control System

The traction control system aids in the prevention of excessive wheel spin which will allow the vehicle to maintain traction during acceleration. This is accomplished in the same manner as anti-lock braking but also includes the use of the PCM for modulating engine torque.

ESC 

The ESC  system constantly monitors vehicle direction of travel relative to the driver's intended course and aids in keeping the vehicle traveling along that course. This is accomplished in the same manner as anti-lock braking and traction control.

When one or both of the above systems activate, the driver may notice the same operational symptoms as ABS along with the following additional symptoms:

• A small deceleration or a reduction in the acceleration of the vehicle (PCM modulating engine torque)
• The stability/traction control indicator (also known as the sliding-car icon) flashes (indicating a traction or stability event is taking place)
