Antilock Brake System With Electronic Stability Program: Notes
This vehicle uses an electronic brake control system designated MK25e. This system includes ABS (Antilock Brake System), TCS (Traction Control System), BAS (Brake Assist System), EVBP (Electronic Variable Brake Proportioning) and ESP® (Electronic Stability Program). All of these systems work together to enhance vehicle stability and control in various driving conditions and are commonly referred to as ESP.
This system uses components of the base brake system, but also features the following components:
- Integrated Control Unit (ICU) - Includes Hydraulic Control Unit (HCU) (2) and Antilock Brake Module (ABM) (1).
- Wheel Speed Sensors (WSS) - Four sensors (one at each wheel).
- Dynamics Sensor - Includes a yaw rate sensor and a lateral accelerometer.
- Steering Angle Sensor (SA) - The SAS is part of the Steering Column Control Module (SCCM).
- Brake Pressure Sensor - The brake pressure sensor is located in the HCU and is not serviceable separate from the HCU.
