What Causes Both the ABS and Anti-Skid Lights to Illuminate in a Car?
1 Answers
The ABS and anti-skid lights in a car illuminate due to sensor damage. It is necessary to check the wiring connections and reconnect any loose ones. Components of the ABS System: The ABS system mainly consists of four parts: wheel speed sensors, electronic control unit (ECU), hydraulic unit, and ABS warning light. The wheel speed sensors detect the motion state of the wheels and emit sinusoidal electronic pulse AC signals. These signals are then processed by a modulator, converted into digital signals, and transmitted to the electronic control unit. The electronic central control unit (ECU) receives input signals from the wheel speed sensors. Using these parameters, it calculates the wheel speed, vehicle speed, and slip rate. Based on the slip rate, it determines the wheel state and issues control commands to the hydraulic unit. The hydraulic unit adjusts the pressure in the brake lines according to the control commands. The adjustment process includes pressure maintenance, pressure increase, and pressure decrease. The ABS warning light alerts the driver to any system malfunctions. Functions of ABS: Maximize the effectiveness of the brakes, reducing braking time and distance. Effectively prevent vehicle skidding and fishtailing during emergency braking, ensuring good driving stability. Allow steering during emergency braking, providing good steering maneuverability. Avoid severe friction between the tires and the ground, reducing tire wear.
