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 100Ω resistor must be used as shown.
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 : 0.59 V ~ 0.84 V
V_high : 1.18 V ~ 1.68 V
Frequency range : 1~2,500 Hz
