DYNAMIC STABILITY CONTROL 04–15–11 04–15 DSC CM PART FUNCTION E5U041543750N04 • The DSC CM makes calculations using signals input from each sensor, outputs a brake fluid pressure control signal to the DSC HU to actuate DSC system functions and outputs an engine output control signal to the PCM. • The DSC HU/CM controls the following functions: Function Table Function name Contents ABS control function • Controls brake fluid pressure when braking to maintain directional stability, ensure steerability and reduce stopping distance. EBD (Electronic Brakeforce Distribution) control • Constantly controls proper distribution of brake fluid pressure to the front and rear wheels according to vehicle load, road surface and vehicle TCS control function • Controls traction to within the road surface friction limit and according to road and driving conditions to improve starting and acceleration DSC control function • Suppresses strong over-steer and under-steer tendencies when turning by controlling engine output and braking of each wheel to assure driving CAN signal function • Transmits the wheel speed signal to the PCM using CAN communication. On-board diagnostic system • A function that allows important parts of the DSC control system to perform self-diagnosis. In case a malfunction occurs, the warning lights • When a malfunction is determined as a result of the on-board diagnosis test, system control is suspended or limited to prevent any dangerous |
