ABS Actuator and Electric Unit (Control Unit): Actuator

WARNING: This page is about a different car, the 2019 Nissan NV3500 HD, 2019 Nissan NV2500 HD, and 2019 Nissan NV1500. However, it is still accessible from the selected car via links, so may be relevant.

The following components are integrated with ABS actuator:

Motor/Accumulator Assembly

Pump

Operates the pump drive according to signals from ABS actuator and electric unit (control unit) by the motor.

Motor

Operates the motor drive according to signals from ABS actuator and electric unit (control unit).

Accumulator

The accumulator accumulates brake fluid conveyed by the motor and pump.

Motor Relay

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

Actuator Relay (Main 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).

Cut Valve 1, Cut Valve 2

Shuts off the ordinary brake line from master cylinder to signals from ABS actuator and electric unit (control unit).

Suction Valve 1

Suction valve 1 switches the brake path to convey accumulator pressure to the front system, according to a signal transmitted from the ABS actuator and electric unit (control unit).

Suction Valve 2

Suction valve 2 releases accumulator pressure, according to a signal transmitted from the ABS actuator and electric unit (control unit).

Accumulator Pressure Sensor

The accumulator pressure sensor detects brake fluid pressure accumulated in the accumulator and conveys the detected result to the ABS actuator and electric unit (control unit).

Master Cylinder Pressure Sensor

Detects the brake fluid pressure of master cylinder part and transmits a signal to ABS actuator and electric unit (control unit).
