What Causes Frequent ABS Intervention During Low-Speed Braking?

[McDominic]

Low-speed braking ABS false intervention reasons are as follows: Reason 1: The ABS speed sensor's sensing part is covered by mud, sludge, or other contaminants, affecting the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from determining the vehicle speed and calculating the wheel slip rate, thus failing to issue appropriate commands to regulate braking. Solution: Clean the dirt from 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 in the system wiring or poor contact in 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: Inspect the wiring connections and reconnect any loose parts.
