DSC CM PART FUNCTION

id041500101000
• 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 | Content

ABS control function | • When braking, maintains direction stability during braking operation, secures handling and provides shortened braking distance by control of brake fluid pressure.
EBD (Electronic brakeforce distribution) control | • Prevents rear-wheel lockup through optimum control of normal brake fluid pressure distribution to front and rear wheels in response to vehicle load, condition of road surface and vehicle speed.
TCS control | • Provides improved safety of start and acceleration performance by keeping traction within limits of road surface friction in response to road and vehicle speed conditions.
DSC control | • Inhibits strong tendency of the vehicle to oversteer or understeer, by controlling engine torque and braking on each wheel to provide assured vehicle stability.
Brake assist control | • Controls the fluid of the wheel cylinder during emergency braking, provides increased fluid pressure to each wheels.
Vehicle speed output | • Outputs the vehicle speed signal to the Body Control Module (BCM). • The value of the calculation from the 4 wheel-speed sensors is output as a speed signal to CAN communication line.
Diagnostic system | • Important parts in the DSC control have a self-detection function that, in the event of any abnormality, illuminate each warning light to inform the driver of an abnormality together with recording the DTC in the DSC unit. • When occurrence of an abnormality is judged by self-detection, cancels the controls so as not to cause loss of driving safety.
