- A fault is detected if noise of the wheel speed sensor signal is detected.
- A fault is detected if the wheel speed sensor signal is lost, or the wheel speed sensor signal continuously indicates significantly low speed by calculating the difference between maximum speed and minimum speed among the four wheels.
- A fault is detected if the wheel speed sensor signal continuously indicates excessively high or low speed.
- A fault is detected if the wheel speed sensor signal changes irregularly.
- A fault is detected if the wheel speed sensor signal drops cyclically.
