Traction Control System

The traction control system, if equipped, consists of or uses the following components:
- Anti-lock brake control module.
- Powertrain Control Module (PCM).
- Front anti-lock brake sensor.
- Rear anti-lock brake sensor.
- Traction control switch.

The traction control system:
- Is operational when the ignition switch is in the RUN position.
- Can be disabled by the driver depressing the traction control switch. The traction control system will reset when the ignition switch is cycled or when the traction control switch is depressed.
- Is controlled by the anti-lock brake control module.
- Applies and releases the appropriate rear brake to reduce wheelspin and aid traction if one or both rear wheels lose traction and begin to spin during acceleration.
- Interacts with the powertrain control module to reduce engine torque if one or both rear wheels lose traction and begin to spin during acceleration.
- Automatically stops traction control system cycling if the brakes are manually applied during traction control system operation.
- If in operation continually on slippery roads, the anti-lock brake control module may disable the system to prevent overheating of the rear brakes. When the cool down time limit expires traction control is restored. (Anti-lock braking is fully functional during the cool down period.)
- When the traction control system is disabled either by the driver or by the anti-lock brake control module, both rear brake modulation and engine torque modulation are disabled.
- With the traction control system on, brake modulation to the spinning wheel is achieved by the anti-lock brake control module closing the isolation valves to the non-affected wheels and running the pump motor that provides hydraulic pressure for brake modulation to the spinning wheel.
- Engine torque modulation is achieved by the anti-lock brake control module interacting with the powertrain control module to regulate fuel and spark.
