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 eplained in terms of DSC system
functions.
Part name
DSC HU/CM
PCM
DSC indicator light
DSC OFF switch
DSC OFF light
Wheel speed sensor
Combine sensor
Steering angle sensor
P–10
DYNAMIC STABILITY CONTROL
• 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.
• Controls engine torque based on the signal from DSC HU/CM.
• Transmits engine conditions and tire information to DSC HU/CM through CAN.
• Notifies driver of DSC operation (Vehicle is in side slip situation).
• Notifies driver of TCS operation (Drive-wheel slippage situation).
• DSC system non-operation based on driver intention is transmitted to DSC HU/
CM.
• Notifies driver of DSC system non-operation by DSC OFF switch.
• Notifies driver of DSC system is forbidden by fail-safe function.
• Detects rotation state of each wheel and transmits signal to the DSC HU/CM.
• Detects lateral-G force and yaw rate (vehicle cornering angle velocity) of vehicle
and transmits to DSC HU/CM.
• Detects steering angle and transmits to the DSC HU/CM.
