Functional description |
Sensor |
Wheel speed sensor |
1 |
Outputs the frequency signal in proportion to the rotation speed of each wheel to ASC-ECU. |
Sensor |
Magnetic encoder for wheel speed detection |
2 |
The wheel speed sensor is a pulse generator. When the magnetic encoder for wheel speed detection (a plate on which north and south pole sides of the magnets are arranged alternately) rotates, it outputs frequency pulse signal in proportion to each wheel speed. |
Sensor |
Stop lamp switch |
3 |
Outputs the signal indicating whether the brake pedal is depressed or not to ASC-ECU. |
Sensor |
G & yaw rate sensor |
4 |
Is integrated in the ASC-ECU, detects the yaw rate and longitudinal and lateral acceleration of a vehicle, and sends a signal to the ASC-ECU. |
Sensor |
Steering wheel sensor |
5 |
Steering wheel sensor |
Sensor |
ASC OFF switch |
6 |
Outputs the ON/OFF signal for ASC to ASC-ECU. |
Sensor |
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. |
Sensor |
Brake auto hold switch |
8*2 |
Outputs the ON/OFF signal for brake auto hold to the ASC-ECU |
Actuator |
Hydraulic unit |
9 |
Drives the solenoid valve using the signal from ASC-ECU, and controls the brake fluid pressure for each wheel. |
Actuator |
ABS warning lamp |
10 |
Informs the driver of the system status by illuminating, flashing, or turning off the ABS warning lamp according to the signal from ASC-ECU. |
Actuator |
ABS warning display |
11 |
Informs the driver of the system status by illuminating or turning off the ABS warning display according to the signal from ASC-ECU. |
Actuator |
Brake warning lamp |
12 |
Used as the brake warning lamp 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 lamp according to the signal from ASC-ECU. |
Actuator |
Brake warning display |
13 |
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. |
Actuator |
ASC operation lamp |
14 |
Informs the driver of the system status by flashing when the system operates according to the signal from ASC-ECU. |
Actuator |
ASC OFF lamp |
15 |
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 brake TCL stops by flashing the ASC OFF lamp for the duration of approximately 2 Hz. |
Actuator |
ASC warning display and lamp |
16 |
TCL function and stability control function, HSA function use the same display and lamp. Depending on the signal from ASC-ECU, the ASC warning display and lamp informs the driver of the system status by illuminating when the system has malfunction (When the ASC warning display and lamp is illuminated, the HSA function does not operate). |
Actuator |
Brake auto hold indicator lamp |
17*2 |
Informs the driver of the system operates by illuminating by the signal from ASC-ECU. |

4WD-ECU* |
- |
21*1 |
Outputs the drive status to ASC-ECU.
4WD-ECU performs integrated control with ASC-ECU. |
Electric parking brake ECU |
- |
22*2 |
Outputs the auto hold switch status to ASC-ECU. |
ASC control unit (ASC-ECU) |
- |
23 |
- 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 M.U.T.-IIISE).
