    North America Customer Care at 855-228-3203. Electronic Control Unit (ECU) Figure 1.1 The ECU is the control center or “brain” of the ABS, RSC and ESC systems. It receives information from the sensors, processes data and sends signals to modulators and active braking valves to achieve different tasks.

  • Page 11: Roll Stability Control (Rsc)

    RSC uses many of the same components used by ABS/ATC including modulator valves, active braking valves and wheel speed sensors. RSC ECUs are different from ABS ECUs as they contain an internal accelerometer that measures and updates the lateral acceleration of the vehicle and compares it to a critical threshold at which rollover may occur.

    HSA Components HSA is available on ABS ECUs with E4.4 software revision or higher. Same as ESC, HSA is built from the ABS platform and uses many of the same components as ATC and RSC. HSA uses the front axle active braking valve as well as the rear active braking valve to help maintain the pressure trapped during HSA activation.
