NOTE:
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)
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).]
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.
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
NOTE: ABS function, EBD function and Brake limited slip differential (BLSD) function control operates.
Hill Descent Control Switch
