Antilock Brake System (ABS)

ANTILOCK BRAKE SYSTEM (ABS)





This vehicle uses the Bosch� system 8 braking system. ABS is standard on all vehicles. ESP is optional.


This antilock brake system uses components of the base brake system, but also features the following components:

- Integrated Control Unit (ICU) - Includes Hydraulic Control Unit (HCU) (4) and Antilock Brake Module (ABM)
- Wheel Speed Sensors (WSS) - Four sensors (one at each wheel)
- Dynamic Sensor module (includes Yaw rate sensor and lateral acceleration sensor) if equipped with ESP
- Steering angle Sensor (part of the airbag clock spring if equipped with ESP


ABS

The purpose of the antilock brake system (ABS) is to prevent wheel lockup under braking conditions on virtually any type of road surface. Antilock braking is desirable because a vehicle that is stopped without locking the wheels retains directional stability and some steering capability. This allows the driver to retain greater control of the vehicle during braking.

ABS uses the following components to operate:

- ICU - Integrated Control Unit
- 4 wheel speed sensors
- G- Sensor (ABS 4X4 vehicles)

The ICU is mounted on the frame in the engine compartment. The Wheel speed sensors are mounted to each front and rear hub/bearing. The G- Sensor is located internally in the electronic control unit (ECU) and is not separately serviceable.
