What Causes the Vehicle Anti-lock Braking System Light to Illuminate?

[DavidAnn]

Here are the specific reasons why a vehicle's ABS (Anti-lock Braking System) warning light may illuminate: 1. ABS pump malfunction or power/ground circuit failure in the ABS pump. 2. Loose sensor connectors or failure of a specific sensor. 3. Related fuse blown or burned out. 4. Blocked system signal transmission. 5. False alarm due to system misreporting. Below is extended information about the ABS system: 1. Function of ABS system: ABS is the vehicle's anti-lock braking system, which belongs to the active safety systems of automobiles. When the ABS light comes on, it indicates that the vehicle's computer has detected a fault in the ABS system. 2. Reasons for ABS light illumination: Under normal driving conditions, the ABS remains dormant. It only activates during emergency braking situations, such as hard braking at high speeds, when the vehicle's computer determines that ABS intervention is necessary. When the ABS light illuminates, it is often due to the wheel speed sensors not functioning properly. The ABS computer cannot detect the driving conditions of each tire or compare the slippage amounts of individual wheels, resulting in the ABS system's inability to operate correctly.
