ESP ABS and Traction Conrol
Today's electronic traction control system extends the ABS brake system and adds torque management, reducing engine power to prevent wheel spin.
The ESP Electronic Stability Program controls the ABS and the TCS. It automatically applies individual brake units when it senses the vehicle's about to bulldoze ahead or spin out of control.
The system automatically kicks into action when the steering does not match the vehicle's direction. First, the control module monitors steering, wheel speed, and yaw rate sensors. Then, if an emergency like a sudden swerve, or an over or understeer occurs, it applies brake units and reduces engine speed until the driver regains control.
The TCS Traction Control System can be disabled for driving in mud, snow, or sand. A warning light stays illuminated until the driver pushes a switch or button, reactivating the system. Deactivating the traction control program disables skid control.
