ABS alarm lights and brake alarm lights occasionally shine

Many car owners will react to the OCCASIONAL alarm lights and brake alarm lights on the car occasionally shining, so what are the main reasons for this phenomenon?

(1) Where the ABS line plug is loose, the contact is poor or there is a line wear and tear.

(2) The speed sensor is faulty and the correct speed signal cannot be transmitted to the ABS control unit.

(3) The wheel bearing is loose, so that the gap between the gear ring and the speed sensor changes, and the correct speed signal cannot be sensed.

(4) There is air in the brake pipeline, which affects the normal operation of ABS.

(5) The brake sub-pump operation is poor, although the ABS control unit issues the correct instructions, but the brake sub-pump works poorly, and the speed signal sent back by the speed sensor indicates that the brake deceleration cannot meet the requirements.

ABS fault light flashes, indicating that ABS is faulty; The brake alarm light is always on, indicating that the parking brake switch is damaged or the liquid level of the brake fluid is reduced; Two lights are flashed at the same time, indicating that one or more of the control units, speed sensors, hydraulic regulation devices and electronically controlled brake distribution devices in the ABS have failed; The two lights occasionally shine, and the ABS is working normally, indicating that the main devices of the ABS are working normally, which may be due to poor line contact or mechanical loosening
