How to resolve the illuminated ABS light on a Buick Excelle?
1 Answers
Supplementing sufficient brake fluid is required to eliminate the warning light. Below are the reasons for the ABS warning light illumination: 1. System malfunction caused by loose connections between system circuits: The most common scenario is a loose speed sensor wire connector triggering the fault. This condition will also display a poor speed sensor signal in the ABS computer's fault memory. 2. ABS speed sensor sensing area being obstructed: This affects the sensor's ability to detect corresponding speed signals, preventing the ABS computer from determining vehicle speed or calculating wheel slip rates, thus failing to issue appropriate commands to adjust braking. Simply cleaning the obstruction on the speed sensor will restore normal functionality.
