What is the fault when the ABS light is on in the Fit?

[DelAdriel]

The reasons for the ABS light being on in the Fit are as follows: Reason 1: The sensing part of the ABS speed sensor is covered by dirt, mud, 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 the wheel slip rate, thus failing to issue appropriate commands to adjust 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 operation. Reason 2: Poor signal due to loose connections between system lines or poor contact in the ABS relay, leading to system failure. The most common issue is a loose connection in the speed sensor wiring, which causes the fault. In such cases, the ABS computer's fault memory will also display a poor speed sensor signal. Solution: Check the wiring connections and reconnect any loose parts.
