ABS Actuator and Electric Unit (Control Unit)INFOID:0000000009463743
Electric unit (control unit) is integrated with actuator and comprehensively controls VDC function, TCS func-
tion, ABS function and EBD function.
ELECTRIC UNIT (CONTROL UNIT)
• Brake fluid pressure is controlled according to signals from each sensor.
• If malfunction is detected, t he system enters fail-safe mode.
ACTUATOR
The following components are integrated with ABS actuator.
Pump
Returns the brake fluid reserved in reservoir to master cylinder by reducing pressure.
Motor
Activates the pump according to signals from ABS actuator and electric unit (control unit).
Motor Relay
Operates the motor ON/OFF according to signals fr om ABS actuator and electric unit (control unit).
Actuator Relay (Main Relay)
Operates each valve ON/OFF according to signals fr om ABS actuator and electric unit (control unit).
ABS IN Valve
Switches the fluid pressure line to increase or hold according to signals from control unit.
ABS OUT Valve
Switches the fluid pressure line to increase, hold or decrease according to signals from control unit.
Cut Valve 1, Cut Valve 2
Shuts off the ordinary brake line from master cylinder, when VDC function and TCS function are activated.

< SYSTEM DESCRIPTION >[VDC/TCS/ABS]
COMPONENT PARTS
Suction Valve 1, Suction Valve 2
Supplies the brake fluid from master cylinder to t
he pump, when VDC function and TCS function are activated.
Return Check Valve
Returns the brake fluid from brake caliper and wheel cy linder 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 vehicle, 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:0000000009463744
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 el ectric unit (control unit). Change
of magnetic field is proportional to wheel speed.
Stop Lamp SwitchINFOID:0000000009463745
Detects the operation status of brake pedal and transmits converted electric signal to ABS actuator and elec-
tric unit (control unit).
Steering Angle SensorINFOID:0000000009463746
Detects the following information and transmits steering angl e 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
Brake Fluid Level SwitchINFOID:0000000009463747
Detects the brake fluid level in reservoir tank and transmi ts converted electric signal from combination meter to
ABS actuator and electric unit (control unit) via CAN communication.
Vacuum SensorINFOID:0000000009463748
Detects the vacuum in brake booster and transmits conver ted electric signal to ABS actuator and electric unit
(control unit).
