Why does the ABS light come on?

[StGriffin]

ABS light comes on due to weakened signals or loose wiring. The solution is to clean the sensors thoroughly and reinstall the wiring. When the sensing part of the ABS speed sensor is covered by dirt, mud, or other contaminants, it affects the sensor's ability to detect the corresponding speed signal. This prevents the ABS computer from identifying the vehicle speed and determining 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 ring to restore normal operation. System malfunctions can also occur due to poor signal quality caused by loose connections between system lines or poor contact in ABS relays. The most common issue is a loose speed sensor wire connection, which will also show as a poor speed sensor signal in the ABS computer's fault memory. Solution: Check all wiring connections, reconnect any loose parts, and verify if the fault is resolved.
