DYNAMIC STABILITY CONTROL 04–15–3 04–15 End Of Sie DYNAMIC STABILITY CONTROL (DSC) STRUCTURAL VIEW E5U041500000N02 End Of Sie DYNAMIC STABILITY CONTROL (DSC) CONSTRUCTION E5U041500000N03 • 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 BRAKE BRAKE SYSTEM ABS WARNING REAR ABS WHEEL- FRONT ABS WHEEL- DSC OFF LIGHT DSC INDICATOR LIGHT STEERING ANGLE COMBINED DSC OFF SWITCH DSC HU/CM PCM TCM (AT) E5U415ZS5002 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 • 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 • 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. |
