- dSC unit and hydraulic unit are integrated for improved serviceability;
- lateral G-sensor and yaw rate sensor combined to improve maintainability;
- brake fluid pressure sensor integrated into DSC HU/CM;
- dSC HU/CM block I/O pins have been changed;
- electric brake assist is used to improve safety;
- the DSC switch is used to disable DSC operation;
- the DSC HU/CM system outputs the speed signal to the audio unit, windshield wiper and washer switch, vehicle navigation unit, cruise control actuator and the leveling-by-wire control unit, and outputs the speed signal via CAN;
- cAN communication system is used.
