• The DSC HU/CM sends and receives data to and from other modules via the CAN system. Refer to Section 09 for a detailed explanation of the CAN. (See CONTROLLER AREA NETWORK (CAN) SYSTEM OUTLINE.)

## Transmit Information

### Except L3 Turbo

  • Torque reduction request to PCM
  • Brake system configuration to instrument cluster
  • Brake system status to PCM
  • Wheel speed to 4WD control module and PCM
  - Front left
  - Front right
  - Rear left
  - Rear right
  • Desired coupling torque to 4WD control module

### L3 Turbo

  • Travelled distance to PCM
  • Steering wheel angle to 4WD control module
