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.
7. Rear wheel sensor LH (RH similar) 8. VDC OFF switch 9. Steering angle sensor
(view with steering wheel removed)
10. Parking brake switch 11. Stop lamp switch 12. Combination meter
