The three main reasons why the ABS lights are on, the solutions that car owners must know
When the ABS light on the dashboard of your car is on, many car owners will feel confused and overwhelmed. ABS, or anti-lock braking system, is an important guarantee for the safe driving of the car. So, what exactly does it mean for the ABS light to be on? This article will analyze the three reasons why ABS lights are on in detail and provide corresponding solutions.
1. ABS sensor failure
The ABS sensor is an important part of the ABS system and is responsible for monitoring the rotational speed of the wheels. When the sensor fails, the ABS system cannot accurately obtain the wheel speed information, resulting in the ABS light illuminating. To solve this kind of problem, car owners can try the following methods:
Cleaning the sensor: Sometimes dirt or foreign objects attached to the surface of the sensor can cause it to work abnormally, and it may return to normal after cleaning the sensor.
Check the sensor circuit: check whether the circuit between the sensor and the ABS control unit is intact, and repair it in time if it is damaged or in poor contact.
Replace the faulty sensor: If the sensor is confirmed to be damaged after inspection, it needs to be replaced with a new sensor.
Second, the ABS control unit failure
The ABS control unit is the "brain" of the ABS system, which is responsible for processing the signals from the sensors and controlling the work of the braking system. When the control unit fails, it will also cause the ABS light to turn on. There are ways to deal with such problems:
Restart the vehicle: Sometimes the ABS light may be on due to a temporary failure of the control unit, which may return to normal after restarting the vehicle.
Software update: There may be bugs in the control unit software of some models, and you need to go to the 4S store to update the software.
Replace the control unit: If the control unit is confirmed to be damaged after inspection, it needs to be replaced with a new control unit.
3. Brake system failure
The braking system is the key to the safe driving of the car and is closely connected with the ABS system. When the brake system fails, such as brake fluid leakage, brake pad wear and tear, etc., it may also cause the ABS light to turn on. Solutions to such problems include:
Check the brake fluid: Regularly check the level and quality of the brake fluid, and add or replace it in time if the brake fluid is insufficient or deteriorated.
Check the brake pads: check the wear of the brake pads, and replace them in time if the wear is serious. At the same time, pay attention to check whether the brake disc is smooth, and if there are grooves or deformations, it should be dealt with in time.
Check the working conditions of other parts of the brake system: such as brake master cylinder, sub-cylinder and other components, and repair or replace them in time if there is any abnormality.
