COMPONENTS AND FUNCTIONS CHART
| Name of part | No. | Functional description | |||||||
|---|---|---|---|---|---|---|---|---|---|
| Sensor | Wheel speed sensor | 1 | Outputs the frequency signal in proportion to the rotation speed of each wheel to ASC-ECU. | ||||||
| Magnetic encoder for wheel speed detection | 2 | When the magnetic encoder for wheel speed detection (a plate on which north and south pole sides of the magnets are arranged alternately) rotates, the wheel speed sensor outputs frequency pulse signal in proportion to each wheel speed. | |||||||
| Stop light switch | 3 | Outputs the signal indicating whether the brake pedal is depressed or not to ASC-ECU. | |||||||
| G&yaw rate sensor | 4 | Detects the yaw rate, and longitudinal <AWD> and lateral acceleration of a vehicle, then outputs the signal to ASC-ECU via the CAN line. | |||||||
| Steering wheel sensor | 5 | Detects the steering angle of the steering wheel, and outputs signal to ASC-ECU via the CAN bus line. | |||||||
| ASC OFF switch | 6 | Outputs the ASC ON/OFF signal to ASC-ECU. | |||||||
| Brake fluid pressure sensor | 7 | Integrated into the hydraulic unit, and outputs the signal for the brake fluid pressure in the master cylinder to ASC-ECU. | |||||||
| Actuator | Hydraulic unit | 8 | Drives the solenoid valve using the signal from ASC-ECU, and controls the brake fluid pressure for each wheel. | ||||||
| ABS warning light | 9 | Informs the driver of the system status by illuminating, flashing, or turning off the ABS warning light according to the signal from ASC-ECU. | |||||||
| ABS warning display | 10 | Informs the driver of the system status by illuminating or turning off the ABS warning display according to the signal from ASC-ECU. | |||||||
| Brake warning light | 11 | Used as the brake 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 brake warning light according to the signal from ASC-ECU. | |||||||
| Brake warning display | 12 | Used as the brake warning display for the brake fluid level, and EBD control. Informs the driver of the system status by illuminating or turning off the brake warning display according to the signal from ASC-ECU. | |||||||
| ASC operation display and light(3) | 13 | Informs the driver of the system status by flashing when the system operates according to the signal from ASC-ECU. | |||||||
| ASC OFF display | 14 | Informs the driver of the system shutdown by illuminating by the signal from ASC-ECU. Informs the driver that the brake system overheats and the TCL control (brake control only) is disabled by flashing the ASC OFF display at a frequency of approximately 2 Hz. | |||||||
| ASC warning display and light(3) | 15 | TCL function and stability control function, HSA function use the same display and light(3). Depending on the signal from ASC-ECU, the ASC warning display and light(3) informs the driver of the system status by illuminating when the system has malfunction (When the ASC warning display and light(3) is illuminated, the HSA function does not operate). | |||||||
| Data link connector | 16 | Sets the diagnostic trouble code and establishes the communication with scan tool. | |||||||
| Engine control module (ECM) | 17 | Controls the engine output based on the signal from ASC-ECU. | |||||||
| TCM(2) | 18(2) | TCM performs integrated control with ASC-ECU. Output the gear position to ASC-ECU. |
|||||||
| TC-SST ECU(1) | 19(1) | TC-SST-ECU performs integrated control with ASC-ECU. Outputs the gear position to ASC-ECU. |
|||||||
| AWC ECU(1) | 20(1) | Outputs the drive status to ASC-ECU. AWC-ECU performs integrated control with ASC-ECU. |
|||||||
| ASC control unit (ASC-ECU) | 21 | Controls the actuators (hydraulic unit) based on the signals sent from sensors. | |||||||
| Controls the self-diagnostic function and fail-safe function. | |||||||||
| Controls diagnostic function (Compatible with scan tool). | |||||||||
