For 1990-2009 cars

The purpose of the Delco Bosch 5 Antilock Brake System (ABS) is to minimize wheel slip during heavy braking. The Delco Bosch 5 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 wheel. If excessive front wheel speed is detected in either front wheels the TCS will be activated. The TCS uses the following to improved traction and vehicle stability:

• | Fuel control

• | Timing control

• | front brake intervention
