How the ABS system works and its importance in the car

It is one of the modern systems in the car that is of great benefit, as many customers are keen when buying a car to have an ABS system in the car. This system prevents wheel slippage as a result of the brakes being closed, as when suddenly pressing the brake the wheel does not stop but will still crawl on the ground This means that the brakes are not completely closed, but in the case of the ABS system, it works to regulate the braking process and regulates the oil pressure reaching the brakes so that the wheel does not slip on the ground.
How the ABS system works in a car

ABS is important when the driver suddenly applies force to the brakes if something appears in front of the vehicle or approaches another vehicle while driving.
When the driver suddenly presses the brakes and this situation does not happen much in emergency cases only, this makes the driver lose control of the car and this may lead to accidents, but in the case of the ABS system, it works not to lock the wheels even while pressing the brakes Through which it is possible to control the car and not lose control of it, which makes the driver control the car, it also works to reduce the stopping distance, especially if the ground is wet or has sand.
This system mainly depends on the breakdown of the oil pressure reaching the brakes, and this fragmentation occurs within fractions of a second, leading to the driver feeling a jerk in the brake pedal. This occurs while the ABS is doing its work. ABS system components 
 

There are four main components to this system, which are:

• Speed sensitive

The number of sensors varies from one system to another, as there are systems that have two sensors on the rear wheels or four sensors on all wheels, and the function of this sensor sends a signal to the control unit when the wheels stop.

• valves

The number of valves varies from one type to another and they regulate the oil pressure that reaches the brakes 

• pump

This pump helps in the work of the valves as it works to return the oil through the valve.

• Control unit

It receives information from the sensors and through this information controls the valves.

Checking the ABS system
When the ABS system malfunctions, the driver feels a loss of control of the vehicle and the wheels creep when suddenly depressing the brake pedal. This may be due to:

Problems with the sensor itself
The sensor must be removed, cleaned, and then put back in its place.

Problems with the sensor connection wires
The wire connected to the ECU must be checked and checked for cuts, water or traces of rust.
