Part name

Function

DSC HU/CM

  • Makes calculations using input signals from each sensor, controls brake fluid pressure to each wheel, and actuates function (ABS, EBD, TCS, DSC, brake assist control, roll over mitigation (ROM), hill launch assist (HLA), and TPMS) 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, engine torque, brake switch status, and accelerator pedal position data via CAN communication to the DSC HU/CM.

  • Transmits gear/shift lever position data via CAN communication to the DSC HU/CM. (MTX)

TCM (ATX)

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

EPS CM

  • Transmits steering angle data via CAN communication to the DSC HU/CM.

SAS control module

  • Detects the lateral-G (vehicle lateral acceleration speed), the yaw rate (vehicle turning angle speed), and the longitudinal-G (vehicle longitudinal acceleration speed) via CAN communication to the DSC HU/CM.

Brake system warning light

  • Notifies the driver that the parking brake is applied.

  • Notifies the driver of an ABS or EBD malfunction.

ABS warning light

  • Notifies the driver of an ABS malfunction.

TCS/DSC indicator light

  • Informs the driver that the TCS is operating (drive wheel is spinning).

  • Informs the driver that the DSC is operating (vehicle sideslip occurring).

  • Informs the driver that the Roll over mitigation (ROM) is operating.

  • Informs the driver of DSC system malfunction.

TCS OFF switch

  • Transmits driver intention to release TCS control to the DSC HU/CM.

TCS OFF indicator light

  • Informs driver that TCS control has been released due to TCS OFF switch operation.

Tire pressure monitoring system set switch

  • Data initialization after adjusting the tire pressures can be done.

Tire pressure monitoring system warning light

  • Notifies the driver that the tire pressure is not normal.

  • Notifies the driver of an TPMS malfunction.

ABS wheel-speed sensor

  • Detects the rotation condition of each wheel and transmits it to the DSC HU/CM.

Brake fluid pressure sensor (Built into DSC HU/CM)

  • Detects the fluid pressure from the master cylinder.

WARNING: If the initialization procedure is not completed, the DSC will not operate properly and it might cause an unexpected accident. Therefore, after replacing or removing the DSC HU/ ...

Ebd Control
Outline EBD control uses the ABS system to control brake fluid pressure distribution to the rear wheels so that they do not lock-up prior to the front wheels during braking, thereby preve ...
