What is ABS? | Why Does the ABS Light Come On?

ABS ( Anti-Lock Braking System ) is an electronic system that provides control of the braking processes of vehicles. This system was developed to prevent the wheels from locking. ABS prevents the wheels from locking during vehicle braking, allowing better control of the vehicle.

The main purpose of the Anti-Lock Braking System is to prevent the driver from losing control of the steering wheel when the vehicle brakes. ABS prevents the wheels from locking during braking and the vehicle moves more safely on the road. Especially on slippery surfaces or in sudden braking situations, ABS helps to maintain control of the vehicle.

The ABS system works with sensors that constantly monitor the wheel speeds. These sensors measure the speed of each wheel and detect the difference in wheel speed that occurs during braking. If a wheel speed drops abnormally and there is a risk of locking, the ABS will activate and automatically reduce the brake pressure on that wheel. This prevents the wheel from locking up and provides better control of the vehicle.

ABS system is of great importance for vehicle safety. Especially in emergency situations when sudden braking is required, the presence of ABS provides a great advantage to the driver. Thanks to ABS, the vehicle can overcome a dangerous situation more easily and the driver has more maneuverability.

In conclusion, ABS ( Anti-Lock Braking System ) is an electronic system that prevents locking during braking operations of vehicles and provides the driver with vehicle control. This system, which increases safety for drivers and provides better braking performance, is an important safety feature added to vehicles.

Why Does the ABS Light Come On?

The ABS light comes on when there is a problem with the vehicle's ABS system and warns the driver. When this light comes on, it indicates that the ABS system is temporarily disabled and the normal braking system is active. The ABS light coming on is usually caused by sensor problems, wiring problems or faults in the electronic control unit.

Malfunction Reasons

There are a few common causes of problems that can cause the ABS light to come on. These include:

1. **ABS Sensor Malfunctions:** ABS sensors located on each wheel monitor the wheel speed and transmit this information to the ABS control unit. If the sensors are dirty, damaged or have a connection problem, the ABS system may not work properly.

2. **Wiring Problems:** The wiring between the ABS system sensors and the control unit can become worn or damaged over time. This can prevent the system from receiving accurate data and cause the ABS light to come on.

3. **ABS Control Unit Faults:** The ABS control unit works as the brain of the system and processes the data coming from the wheels. Faults occurring in the control unit may cause the ABS light to come on. These faults are usually caused by problems in the electronic circuits.

4. **Hydraulic Module Failures:** The hydraulic module of the ABS system controls the braking pressure. A failure of the module may cause the brake pressure not to be regulated properly and the ABS light to come on.

Which Parts Are Interchangeable?

When the ABS system fails, certain parts may need to be replaced. Here are some of the parts that may need to be replaced:

1. **ABS Sensors:** Faulty or damaged ABS sensors can be replaced to ensure proper operation of the system.

2. **Cable Connections:** Worn or damaged cables and connections must be replaced to ensure reliable data transmission by the ABS system.

3. **ABS Control Unit:** The faulty control unit must be replaced for the system to work properly. This should generally be done by a professional service.

4. **Hydraulic Module:** Malfunctions in the hydraulic module may require replacement to ensure proper control of braking pressure.
