Wheel Speed Sensor

When the car is stationary the values in the wheel sensor boxes should both be zero. The car should be driven for a short distance. While driving, a number should be displayed in the left wheel sensor box. The value in the box should be proportional to the speed of the vehicle - i.e. the value will increase as the speed increases. As the speed becomes more constant, just the left box should display a value - this indicates the speed signal from the front left ABS sensor (buffered and averaged through the vehicle BeCM).
