Measure the output voltage between the terminal of the wheel speed sensor and the body ground.
In order to protect the wheel speed sensor, when measuring output voltage, a 100 Ω resister must be used as shown.

2.
Compare the change of the output voltage of the wheel speed sensor to the normal change of the output voltage as shown below.

V_low : 0.59V ~ 0.84V
V_high : 1.18V ~ 1.68V
Frequency range : 1 ~ 2,500Hz
