Nissan 47900-0B101 Anti Skid Sensor Assembly Rear

The Anti-lock Brake System (ABS) is supposed to help in maintaining vehicle steerability, the direction in which a car is moving, and the slowest rate of speed at which it loses that direction through severe braking and over rough roads through continuous measurement of the speed of each wheel and regulating brake line pressure to avoid lock up. This type includes the hydraulic actuator, the front and rear wheel velocity sensors, the ABS control unit, the motor of relay and the solenoid relay. There is the electric hydraulic pump and three solenoid operated valves in the actuator assembly to supply hydraulic pressure to the brake system and control the boost pressure of brake lines respectively during the operation. Each wheel has a speed sensor in which sine wave current is created when the toothed sensor rotors turn; this signal is converted digitally by the ABS control unit to determine wheel speed. The control unit is situated near the center console behind it and it works by receiving data from the sensors regarding pressure control and checking for anomalous behavior; this unit turns on the ABS light when the engine is switched on and conducts a preliminary diagnostic test when the vehicle's speed exceeds 4mph. This message must therefore be given attention and while identifying what is wrong might be cumbersome, a diagnostic trouble code can be retrieved by shorting a terminal and observing the patterns of the ABS light. These simple tests range from checking the brake fluid levels, electrical connections, fuses, as well as the brake parts. If the above said elements are found satisfactory then efforts can be made to clear the stored trouble codes and if the problem still remains then it is advised to consult a professional.
