What are the potential failures of the electronically controlled anti-lock brake (ABS) system?

Answer: 1) The malfunction of the chip CPU of the electronic control unit (EBCM).

2) The wheel speed sensor that generates the control command signal is faulty.

3) The failure of the solenoid valve of the actuator that executes the control command.

4) Switching system line pressure and pressure, the hydraulic brake system brake liquid level, the power supply voltage level, the parking brake is released, and other switching faults.

The above possible faults are often indicated by the flashing of the yellow and red lights to give a warning signal to the driver. Some faults (such as the brake fluid level is too low, the parking brake is not released in time, etc.) can be excluded by visual inspection.
