! The DSC system consists of the following parts. While each part has a regular function in other systems, only
the function during DSC control is listed.
End Of Sie
Part name Function
DSC HU/CM
! Makes calculations using input signals from each sensor, controls brake fluid pressure
to each wheel, and actuates each function (ABS, EBD, TCS and DSC) of the DSC
system.
! Outputs the vehicle speed signal to the car-navigation unit.
! Outputs the torque reduction request signal, vehicle speed signal and DSC system
warning control data via CAN lines.
! Controls the on-board diagnostic system and fail-safe function when there is a
malfunction in the DSC system.
PCM
! Controls engine output based on signals from the DSC HU/CM.
! Transmits engine speed, tire and shift position data via CAN communication to the
DSC HU/CM.
TCM (AT)
! Transmits gear/selector lever target position data via CAN communication to the DSC
HU/CM.
DSC indicator light
! Informs the driver that the DSC is operating (vehicle sideslip occurring).
! Informs the driver that the TCS is operating (drive wheel is spinning).
DSC OFF switch ! Transmits driver intention to release DSC control to the DSC HU/CM.
DSC OFF light ! Informs driver that DSC control has been released due to DSC OFF switch operation.
Wheel speed sensor ! Detects the rotation condition of each wheel and transmits it to the DSC HU/CM.
Combined sensor
! Detects the lateral-G (vehicle speed increase) and the yaw rate (vehicle turning angle)
of the vehicle and transmits them to the DSC HU/CM.
Brake fluid pressure sensor (built-
into DSC HU/CM)
! Detects the fluid pressure from the master cylinder and transmits it to the DSC HU/CM.
Steering angle sensor
! Transmits the steering angle and steering angle sensor condition via CAN lines to the
DSC HU/CM.
