Anti-Lock Brake System With Electronic Stability Control
NOTE:
The Electronic Stability Control (ESC) may also be referred to as Electronic Stability Program (ESP) depending on the vehicle model year and configuration. Certain components may also reference ESP, ESC, or use the traction control symbol.
This vehicle uses an electronic brake control system. The system includes ABS (Anti-lock Brake System), EVBP (Electronic Variable Brake Proportioning), TCS (Traction Control System), BAS (Brake Assist System) and ESC (Electronic Stability Control). These system work together to enhance vehicle stability and control in various driving conditions and are commonly referred to as ESC. ESC is standard on this vehicle.
Fig 1: Identifying Integrated Control Unit (ICU) - Hydraulic Control Unit (HCU) And Anti-lock Brake Module (ABM)
This electronic brake control system uses the following components to operate:
- Integrated Control Unit (ICU) - Hydraulic Control Unit (HCU) (2) and Anti-lock Brake Module (ABM) (1).
- Wheel Speed Sensors (WSS) - Four sensors (one sensor at each wheel)
- Dynamics Sensor - The Dynamics Sensor includes the Yaw Rate Sensor, Longitudinal Sensor, and the Lateral Acceleration Sensor.
- Steering Angle Sensor (SAS) - The steering angle sensor is located in the Steering Column Control Module (SCCM) mounted on the steering column.
- Brake Pressure Sensor - The brake pressure sensor is located in the HCU and is not serviceable separate from the HCU.
