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