Cut Valve 1, Cut Valve 2
Shuts off the ordinary brake line from master cylinder, when VDC function and TCS function are activated.
Suction Valve 1, Suction Valve 2
Supplies the brake fluid from master cylinder to the pump, when VDC function and TCS function are activated.
Return Check Valve
Returns the brake fluid from brake caliper and wheel cyli nder to master cylinder by bypassing orifice of each
valve when brake is released.
Reservoir
Temporarily reserves the brake fluid drained from brake caliper, so that pressure efficiently decreases when
decreasing pressure of brake caliper and wheel cylinder.
Yaw rate/side/decel G sensor
Calculates the following information that affects the v ehicle, and transmits a signal to ABS actuator and elec-
tric unit (control unit) via communication lines:
• Vehicle rotation angular velocity (yaw rate signal)
• Vehicle lateral acceleration (side G signal) and longitudinal acceleration (decel G signal)
Pressure Sensor
Detects the brake fluid pressure and transmits signal to ABS actuator and electric unit (control unit).
Wheel Sensor and Sensor RotorINFOID:0000000012430829
NOTE:
• Wheel sensor of front wheel is installed on steering knuckle.
• Sensor rotor of front wheel is integrated in wheel hub assembly.
• Wheel sensor of rear wheel is installed on back plate of rear brake.
• Sensor rotor of rear wheel is installed on rear brake drum.
• Never measure resistance and voltage value using a tester because sensor is active sensor.
• Downsize and weight reduction is aimed. IC for detection portion
and magnet for sensor rotor are adopted.
• Power supply is supplied to detection portion so that magnetic field
line is read. Magnetic field that is detected is converted to current
signal.
• When sensor rotor rotates, magnetic field changes. Magnetic field
change is converted to current signals (rectangular wave) and is
transmitted to ABS actuator and electric unit (control unit). Change
of magnetic field is pr oportional to wheel speed.
Stop Lamp SwitchINFOID:0000000012430830
Detects the operation status of brake pedal and transmits converted electric signal to ABS actuator and elec-
tric unit (control unit).
Steering Angle SensorINFOID:0000000012430831
Detects the following information and transmits steering angle signal to ABS actuator and electric unit (control
unit) via CAN communication:
• Steering wheel rotation amount
• Steering wheel rotation angular velocity
• Steering wheel rotation direction

Front RH brake caliper
• Brake fluid is conveyed to the pump from the master cylinder through suction valve 1 and is pressurized by
the pump operation. The pressurized brake fluid is supplied to the front RH brake caliper through the ABS IN
valve. For the left caliper, brake fluid pressure is maintained because the pressurization is unnecessary. The
pressurization for the left caliper is cont rolled separately from the right caliper.
Front LH brake caliper• Brake fluid is conveyed to the pump from the master cylinder through suction valve 2 and is pressurized by
the pump operation. The pressurized brake fluid is suppl ied to the front LH brake caliper through the ABS IN
valve. For the right caliper, brake fluid pressure is maintained because the pressurization is unnecessary.
The pressurization for the right caliper is controlled separately from the left caliper.
Rear RH wheel cylinder
• Brake fluid is conveyed to the pump from the master cylinder through suction valve 2 and is pressurized by
the pump operation. The pressurized brake fluid is supplied to the rear RH wheel cylinder through the ABS
IN valve. For the left wheel cylinder, brake fluid pressure is maintained because the pressurization is unnec-
essary. The pressurization for the left wheel cylinder is controlled separately from the right wheel cylinder.
Rear LH wheel cylinder• Brake fluid is conveyed to the pump from the master cylinder through suction valve 1 and is pressurized by
the pump operation. The pressurized brake fluid is s upplied to the rear LH wheel cylinder through the ABS
IN valve. For the right wheel cylinder, brake fluid pressure is maintained because the pressurization is
unnecessary. The pressurization for the right wheel cylinder is controlled separately from the left wheel cylin-
der.
