Wheel Sensor and Sensor Rotor

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 rear final drive.
•  Sensor rotor of rear wheel is installed on drive shaft (rear final drive side).
•  Never measure resistance and voltage value using a tester because sensor is active sensor.

• 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 proportional to wheel speed.

ABS Actuator and Electric Unit (Control Unit)

Electric unit (control unit) is integrated with actuator and comprehensively controls VDC function, TCS function, ABS function, EBD function, Brake limited slip differential (BLSD) function, Brake assist function, hill start assist function and Brake force distribution function.

ELECTRIC UNIT (CONTROL UNIT)

•  Brake fluid pressure, engine and transmission are controlled according to signals from each sensor.
•  If malfunction is detected, the 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 from ABS actuator and electric unit (control unit).

Actuator Relay

Operates each valve ON/OFF according to signals from ABS actuator and electric unit (control unit).

ABS IN Valve and ABS OUT Valve

Increases, holds or decreases the fluid pressure of each caliper according to signals from ABS actuator and electric unit (control unit).

Pressure Sensor

Detects the brake fluid pressure and transmits signal to ABS actuator and electric unit (control unit).

Cut Valve 1 (Primary Line), Cut Valve 2 (Secondary Line)

Shuts off the ordinary brake line from master cylinder, when VDC function, TCS function, Brake limited slip differential (BLSD) function, Brake assist function, hill start assist function and Brake force distribution function are activated.

Yaw Rate/Side/Decel G Sensor

Calculates the following information that affects the vehicle, and transmits a signal to ABS actuator and electric unit (control unit). [Yaw rate/side/decel G sensor is integrated in ABS actuator and electric unit (control unit).]

•  Vehicle rotation angular velocity (yaw rate signal)
•  Vehicle lateral acceleration (side G signal)
•  Vehicle longitudinal acceleration (decel G signal)

Stop Lamp Switch

Detects the operation status of brake pedal and transmits converted electric signal to ABS actuator and electric unit (control unit).

Steering Angle Sensor

Detects the following information and transmits steering angle signal to ABS actuator and electric unit (control unit) via CAN communication.

•  Steering angle sensor malfunction signal
•  Steering wheel rotation amount
•  Steering wheel rotation angular velocity
•  Steering wheel rotation direction

Brake Fluid Level Switch

Detects the brake fluid level in reservoir tank and transmits converted electric signal from combination meter to ABS actuator and electric unit (control unit) via CAN communication, when brake fluid level is the specified level or less.

Vacuum Sensor

Detects the vacuum in brake booster and transmits converted electric signal to ABS actuator and electric unit (control unit).

Parking Brake Switch

Detects the operation status of parking brake switch and transmits converted electric signal from combination meter to ABS actuator and electric unit (control unit).

VDC OFF Switch

• This is an integrated switch with switches for other functions.
•  Non-operational status or standby status of the following functions can be selected using VDC OFF switch. VDC OFF indicator lamp indicates the operation status of function. (ON: Non-operational status, OFF: Standby status)

•  VDC function
•  TCS function
•  Active trace control function

NOTE: ABS function, EBD function and Brake limited slip differential (BLSD) function control operates.

•  VDC OFF indicator lamp turns OFF (standby status) when the engine is started again after it is stopped once while VDC OFF indicator lamp is ON (non-operational status).

Hill Descent Control Switch

• The hill descent control system will help maintain vehicle speed on steeper downhill grades. Hill descent control will provide braking allowing the driver to concentrate on steering while reducing the burden and accelerator operation.
