What are the reasons for frequent ABS intervention during low-speed braking?

[McElliot]

The reasons for ABS misintervention during low-speed braking are as follows: Reason 1: The sensing part of the ABS speed sensor is covered by mud, sludge, or other contaminants, affecting the sensor's ability to detect the corresponding vehicle speed signal. This prevents the ABS computer from determining the vehicle speed and the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt on the speed sensor and adjust the gap between the speed sensor and the signal gear ring to restore normal function. Reason 2: Poor signal quality due to loose connections between system lines or poor contact of the ABS relay can cause system malfunctions. The most common issue is a loose speed sensor connector, which leads to faults. In such cases, the ABS computer's fault memory will also display a poor speed sensor signal. Solution: Check the line connections and reconnect any loose parts.
