• The dynamic stability control (DSC)/roll stability control (RSC) system consists of the following parts. While each part has a regular function in other systems, only the function during DSC/RSC control is listed.

Part name | Function
--- | ---
DSC/RSC HU/CM | • Makes calculations using input signals from each sensor, controls brake fluid pressure to each wheel, and actuates each function (ABS, EBD, TCS, DSC and RSC) of the DSC/RSC system. • Outputs the torque reduction request signal, vehicle speed signal and DSC/RSC 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/RSC system.
PCM | • Controls engine output based on signals from the DSC/RSC HU/CM. • Transmits engine speed, tire and shift position data via CAN communication to the DSC/RSC HU/CM.
TCM | • Transmits gear/selector lever target position data via CAN communication to the DSC/RSC HU/CM.
DSC indicator light | • Informs the driver that the RSC is operating. • Informs the driver that the DSC is operating (vehicle sideslip occurring). • Informs the driver that the TCS is operating (drive wheel is spinning).
TCS OFF switch | • Transmits driver intention to release engine TCS control to the DSC/RSC HU/CM.
TCS OFF light | • Informs driver that engine TCS control has been released due to TCS OFF switch operation.
ABS wheel-speed sensor | • Detects the rotation condition of each wheel and transmits it to the DSC/RSC HU/CM.
SAS control module | • Detects the lateral-G (vehicle lateral speed increase), the longitudinal-G (vehicle longitudinal speed increase), the yaw rate (vehicle tuning angle speed), and the roll rate (vehicle inclination angle speed), and transmits them to the DSC/RSC HU/CM via CAN communication.
Brake fluid pressure sensor (Built into DSC/RSC HU/CM) | • Detects the fluid pressure from the master cylinder and transmits it to the DSC/RSC HU/CM.
BCM | • Transmits the steering angle and steering angle sensor condition via CAN lines to the DSC/RSC HU/CM.
