System Outline

This system is composed of the VSA modulator-control unit, the wheel sensor, the steering angle sensor, and the yaw rate-lateral acceleration sensor, and the system indicators in the gauge control module (tach). The VSA modulator-control unit controls the ABS, EBD, TCS, VSA, and brake assist with the brake pressure of each wheel and reduces engine torque to control wheel slippage if necessary.
