Component Description: 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)
