DYNAMIC STABILITY CONTROL (DSC) CONSTRUCTION

id041500100500

• 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.

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 torque reduction request signal, wheel 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.

•  Transmits gear/selector lever position data via CAN communication to the DSC HU/CM.

EPS control module

•  Transmits steering angle 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).

•  Informs the driver of DSC/TCS malfunction.

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.

ABS 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.
