DSC/RSC CONSTRUCTION

id041800817800

• 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.
