When either break light illuminates, it indicates a problem with the braking system that needs to be fixed as soon as possible. A warning light could indicate a sensor problem, some fluid blockage, a fluid leak, a loose wire or a damaged brake component. Faulty brakes can cause a vehicle not to stop or skid when the brakes are applied.

To reset the ABS brake warning light, manually, the key needs to be in the ignition switch and turned forward to the run position, which is located directly before the start position. Loosen the negative cable connection on the battery post with a 10 millimeter box wrench, and remove it.

Leave the cable off for about five minutes to allow the system to reset before reattaching. This resets all of the vehicle's systems, including the clock. Reattach the cable, and tighten the clamp snugly. Check the instrument cluster to confirm the ABS light is extinguished.
