PART NUMBER 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 OFF switch | 3 | Sends a signal to the ABS/TCL-ECU to indicate whether the TCL OFF 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. |
| ABS warning light | 5 | Illuminates in response to signals from the ABS/TCL-ECU when a problem develops in the ABS/TCL system. | |
| Brake warning light | 6 | Illuminates in response to signals from the ABS/TCL-ECU when a problem develops in the EBD system. | |
| TCL indicator | 7 | Flashes when the TCL is activated. Illuminates when the ABS/TCL-ECU is defective. |
|
| 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). | |||
