FUNCTIONS OUTLINE
| NAME OF PART | NUMBER | OUTLINE OF FUNCTIONS | |
|---|---|---|---|
| Sensor | ABS sensor | 1 | Sends alternating current signals at frequencies which are proportional to the rotation speeds of each wheel to the TCL/ASC-ECU. |
| Stoplight switch | 2 | Sends a signal to the TCL/ASC-ECU to indicate whether the brake pedal is depressed or not. | |
| G and yaw rate sensor | 3 | It detects the lateral acceleration, the steering wheel velocity, and the longitudinal acceleration for the vehicle. Then it sends a signal through the CAN bus line to the TCL/ASC-ECU. | |
| Steering wheel sensor | 4 | Detects the steering wheel angle, and sends a signal to the TCL/ASC-ECU through the CAN bus line. | |
| Traction control-OFF switch | 5 | Sends a signal to the TCL/ASC-ECU to turn on and off the traction control. | |
| Pressure sensor | 6 | Is incorporated in the hydraulic unit, and informs the TCL/ASC-ECU of the brake fluid pressure in the master cylinder. | |
| Actuator | Hydraulic unit | 7 | Drives the solenoid valves according to signals from the TCL/ASC-ECU in order to control the brake hydraulic pressure for each wheel. |
| Traction control/Active skid control indicator light | 8 | Receives a signal from the TCL/ASC-ECU, and flashes to inform the driver that the system is operating, or illuminates to inform the driver of system overheat. | |
| Traction control-OFF indicator light | 9 | Receives a signal from the TCL/ASC-ECU, and flashes or illuminates to inform the driver that the system is not operating or defective. | |
| Data link connector | 10 | Sets the diagnostic trouble codes and allows communication with the scan tool. | |
| Powertrain control module (PCM) | 11 | Receives a signal from the TCL/ASC-ECU to control the engine output. | |
| Traction Control/Active Skid Control System control unit (TCL/ASC-ECU) | 12 | Controls actuators (described above) based on the signals coming from each sensor. | |
| Controls the self-diagnostics and fail-safe functions. | |||
| Controls the diagnostic function (scan tool compatible). | |||
