Why would anti lock brakes be on all the time?

Anti-lock brakes (ABS) may remain engaged continuously due to a malfunction or a fault in the ABS control module, wheel speed sensors, or hydraulic system. This could cause the ABS warning light to illuminate on the dashboard. In some cases, environmental factors like a faulty connection or moisture can also lead to persistent activation. If ABS is always on, it is essential to have the vehicle inspected by a professional to ensure safe operation.
