·

The speed sensor signal is excessively noisy.

·

The calculated change in wheel speed is more than 980 m/s2 for 5*1 or 20*2 seconds or more.

·

The calculated change in wheel speed fluctuates between more than 500 m/s2 and less than -500 m/s2 for 5*1 or 20*2 seconds or more.

·

When the vehicle speed is low, excessive noise in the speed sensor pulse signal is detected 3 times or more within 0.005 seconds for 5*1 or 20*2 seconds or more.
