For 1990-2009 cars

The purpose of the Bosch 5.3 Antilock Brake System (ABS) is to minimize wheel slip during heavy braking. The Bosch 5.3 performs this function by monitoring the speed of each wheel and controlling the brake fluid pressure to each wheel independently during a braking event. This allows the driver to retain directional stability and better steering capability.

The Traction Control System (TCS) also monitors rear wheel speed and compares the speed to the speed of the front wheels. If excessive rear wheel speed is detected in either rear wheel the TCS will be activated.
