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
|
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.
|
Stop lamp switch
|
3
|
Outputs the signal indicating whether the brake pedal is depressed
or not to ASC-ECU.
|
G & yaw rate sensor
|
4
|
Detects longitudinal and lateral acceleration of a vehicle, and outputs
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 ON/OFF signal for TCL/ASC to ASC-ECU.
|
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 lamp
|
9
|
Informs the driver of the system status by illuminating, flashing,
or turning off the warning lamp according to the signal from ASC-ECU.
|
Brake warning lamp
|
10
|
Used as the warning lamp for the parking brake, brake fluid level,
and EBD control. Informs the driver of the system status by illuminating, flashing, or turning
off the warning lamp according to the signal from ASC-ECU.
|
ASC indicator lamp
|
11
|
TCL function and ASC function use the same display. Depending on
the signal from ASC-ECU, the indicator lamp informs the driver of the system status by flashing
when the system operates and by illuminating when the system has malfunction.
|
ASC OFF indicator lamp
|
12
|
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 indicator lamp for the duration of approximately 2 Hz.
|
Diagnosis connector
|
13
|
Sets the diagnosis code and establishes the communication with M.U.T.-III.
|
Engine ECU
|
14
|
Controls the engine output based on the signal from ASC-ECU.
|
4WD-ECU
|
15
|
Outputs the drive status to ASC-ECU.
|
ASC control unit (ASC-ECU)
|
16
|
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.-III).
