[Ross]

Buick Excelle ABS pump common faults are as follows: 1. Voltage and fuse issues: The battery voltage is too low or the fuse is blown. 2. Wire breakage and loosening problems: ABS system wires are broken, plugs are loose, or relay connections are not secure. 3. In-vehicle device issues: Poor wheel speed sensor; poor hydraulic regulation device; poor electronic control device, etc. The following is an introduction to ABS: 1. Introduction: The braking system on a car is a very important part. Sometimes the ABS system on the car may fail. After a failure occurs, the ABS indicator light will illuminate to alert the driver. When the anti-lock braking system fails, although the car's brake pedal can still be used, the braking performance will deteriorate, the braking distance will increase, and the handling performance during braking will also worsen. 2. Function: The ABS on a car is used to improve driving safety. When the car encounters an emergency braking situation while driving, it is easy for the wheels to lock up. After the wheels lock up, the friction between the car tires and the ground will decrease. If the front wheels lock up, the car's direction will be very difficult to control. If the rear wheels lock up, the car may experience side skidding during braking.
