How to Replace an ABS Controller in a Toyota Corolla

The anti-lock braking system (ABS) controller for the Toyota Corolla reduces the braking force to any wheel that is rotating significantly more slowly than the others. This helps prevent the brakes from locking during an emergency stop. Your vehicle is not necessarily unsafe to drive if the ABS warning light comes on, but it may mean that you need to replace the ABS.
