COMPONENTS FUNCTION CHART
| NAME OF PART | NUMBER | OUTLINE OF FUNCTION | |
|---|---|---|---|
| Sensor | Wheel speed sensor | 1 | Sends alternating current signals at frequencies which are proportional to the rotation speeds of each wheel to the ABS/TCL-ECU. |
| Stoplight switch | 2 | Sends a signal to the ABS/TCL-ECU to indicate whether the brake pedal is depressed or not. | |
| TCL switch | 3 | Sends a signal to the ABS/TCL-ECU to indicate whether the TCL switch is pushed or not. | |
| Actuator | Hydraulic unit | 4 | Drives the solenoid valves according to signals from the ABS/TCL-ECU in order to control the brake hydraulic pressure for each wheel. |
| Brake warning light | 5 | 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 ABS/TCL-ECU. | |
| ABS warning light | 6 | Informs the driver of the system status by illuminating or turning off the warning light according to the signal from ABS/TCL-ECU. | |
| TCL indicator | 7 | Receives a signal from the ABS/TCL-ECU, and flashes to inform the driver that the system is operating. | |
| TCL OFF indicator | 8 | Illuminates when the TCL is OFF. Illuminates when the ABS/TCL-ECU is defective. |
|
| Data link connector | 9 | Outputs the diagnostic trouble codes and allows communication with the scan tool. | |
| ABS/TCL-ECU | 10 | Controls actuators (described above) based on the signals coming from each sensor. | |
| Controls the self-diagnosis and fail-safe functions. | |||
| Controls the diagnostic function (scan tool compatible). | |||
| Engine control module (ECM) < M/T > | 11 | Receives signals from ABS/TCL-ECU to control the engine output. | |
| Powertrain control module (PCM) < A/T > | Controls the self-diagnosis and fail-safe functions. | ||
| Controls the diagnostic function (scan tool compatible). | |||
