DYNAMIC STABILITY CONTROL

Components and Functions

• 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.

• Outputs speed signal to the audio unit, wiper and washer switch, car-navigation

unit, cruise actuator, and auto leveling control unit through a hard wire

• 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.

Wheel speed sensor • Detects rotation state of each wheel and transmits signal to the DSC HU/CM.

Combine sensor • Detects lateral-G force and yaw rate (vehicle cornering angle velocity) of vehicle

and transmits to DSC HU/CM.

Steering angle sensor • Detects steering angle and transmits to the DSC HU/CM.
