PART FUNCTION OUTLINE CHART
| NAME OF PART | NUMBER | OUTLINE OF FUNCTIONS | |
|---|---|---|---|
| Sensor | Wheel speed 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 yaw angular velocity of 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. | |
| ASC OFF switch | 5 | Sends a signal to the TCL/ASC-ECU to turn on and off the active stability control and traction control. | |
| Master cylinder 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. |
| Brake warning light | 8 | Used as the warning light for the parking brake, brake fluid level, and EBD control. Informs the driver of the system status by illuminating or turning off the warning light according to the signal from TCL/ASC-ECU. | |
| ABS warning light | 9 | Informs the driver of the system status by illuminating or turning off the warning light according to the signal from TCL/ASC-ECU. | |
| TCL/ASC indicator | 10 | Receives a signal from the TCL/ASC-ECU, and flashes (4Hz) to inform the driver that the system is operating. | |
| ASC OFF indicator | 11 | Receives a signal from the TCL/ASC-ECU, and illuminates to inform the driver that the system is not operating, and flashes (2Hz) to inform the driver of system overheat. | |
| Data link connector | 12 | Sets the diagnostic trouble codes and allows communication with the scan tool. | |
| Engine control module (ECM) <M/T> | 13 | Receives signals from the TCL/ASC-ECU to control the engine output. | |
| Powertrain control module (PCM) <A/T> | |||
| Traction Control/Active Stability Control System control unit (TCL/ASC-ECU) | 14 | 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). | |||
