• The DSC system consists of the following components. Moreover, the function of common components in other systems as they are related to each DSC structural component is explained in terms of DSC system functions.

Part name | Function
--- | ---
DSC HU/CM | • Calculates input signal from each sensor, and controls brake fluid pressure applied to each wheel, and activates each DSC system function (ABS, EBD, TCS, and DSC). • Outputs control signal regulating the function of the TCS/DSC system and speed signal through CAN.
• Controls the diagnosis system and fail-safe function when an abnormality is detected in the DSC system.
PCM | • Controls engine torque based on the signal from DSC HU/CM. • Transmits engine conditions and tire information to DSC HU/CM through CAN.
DSC indicator light | • Notifies driver of DSC operation (Vehicle is in side slip situation). • Notifies driver of TCS operation (Drive-wheel slippage situation).
DSC OFF switch | • DSC system non-operation based on driver intention is transmitted to DSC HU/CM.
DSC OFF light | • Notifies driver of DSC system non-operation by DSC OFF switch. • Notifies driver of DSC system is forbidden by fail-safe function.
ABS wheel-speed sensor | • Detects rotation state of each wheel and transmits signal to the DSC HU/CM.
Combined sensor | • Detects lateral-G force, forward-G force (4WD) and yaw rate (vehicle cornering angle velocity) of vehicle and transmits to DSC HU/CM.
Brake fluid pressure sensor (Built-in DSC HU/CM) | • Detects fluid pressure from the master cylinder.
Steering angle sensor | • Detects steering angle and transmits to the DSC HU/CM.
