Most injuries cause focal brain damage, damage confined to a small area of the brain. The focal damage is most often at the point where the head hits an object or where an object, such as a bullet, enters the brain. In addition to focal damage, closed head injuries frequently cause diffuse brain injuries or damage to several other areas of the brain.
As the wheel speed sensor is located very close to the braking system, the high heat generated by the brakes cause the wheel speed sensor to be more susceptible to damage. This in turn makes it one of the more common causes of the ABS light coming on. Unresponsive Hydraulic Pump or Valve.
ABS is malfunctioning: Traction control and ABS (anti-lock braking system) often share the same control module and internal self-diagnostics system. As a result, sometimes an issue in the ABS can trigger the traction control light. If this is the case, then both the ABS and Traction Control lights will be on. Broken wheel speed sensors: Wheel speed sensors are usually in the wheel bearing assembly, and determine the rate at which each wheel is moving.
